  • BOXED WARNING (What is this?)

    WARNING: SUICIDAL THOUGHTS AND BEHAVIORS

    Antidepressants increased the risk of suicidal thoughts and behavior in pediatric and young adult patients in short-term studies. Closely monitor all antidepressant-treated patients for clinical worsening, and emergence of suicidal thoughts and behaviors [see Warnings and Precautions (5.1)].

    Venlafaxine hydrochloride extended-release capsules is not approved for use in pediatric patients [see Use in Specific Populations (8.4)].

  • 1 INDICATIONS AND USAGE

    Venlafaxine hydrochloride extended-release capsules is indicated in adults for the treatment of:

  • 2 DOSAGE AND ADMINISTRATION

    2.1 General Administration Information

    Administer Venlafaxine hydrochloride extended-release capsules in as a single dose with food, either in the morning or in the evening at approximately the same time each day [see Clinical Pharmacology (12.3)].

    Swallow capsules whole with fluid. Do not divide, crush, chew, or place in water.

    The capsule may also be administered by carefully opening the capsule and sprinkling the entire contents on a spoonful of applesauce. This drug/food mixture should be swallowed immediately without chewing and followed with a glass of water to ensure complete swallowing of the pellets (spheroids).

    2.2 Major Depressive Disorder

    For most patients, the recommended starting dose for Venlafaxine hydrochloride extended-release capsules are 75 mg per day, administered in a single dose. For some patients, it may be desirable to start at 37.5 mg per day for 4 to 7 days to allow new patients to adjust to the medication before increasing to 75 mg per day. Patients not responding to the initial 75 mg per day dose may benefit from dose increases to a maximum of 225 mg per day. Dose increases should be in increments of up to 75 mg per day, as needed, and should be made at intervals of not less than 4 days. In the clinical studies establishing efficacy, upward titration was permitted at intervals of 2 weeks or more.

    2.3 Generalized Anxiety Disorder

    For most patients, the recommended starting dose for Venlafaxine hydrochloride extended-release capsules is 75 mg per day, administered in a single dose. For some patients, it may be desirable to start at 37.5 mg per day for 4 to 7 days to allow new patients to adjust to the medication before increasing to 75 mg per day. Patients not responding to the initial 75 mg per day dose may benefit from dose increases to a maximum of 225 mg per day. Dose increases should be in increments of up to 75 mg per day, as needed, and should be made at intervals of not less than 4 days days.

    2.4 Social Anxiety Disorder (Social Phobia)

    The recommended dose is 75 mg per day, administered in a single dose. There was no evidence that higher doses confer any additional benefit.

    2.5 Panic Disorder

    The recommended starting dose is 37.5 mg per day of Venlafaxine hydrochloride extended-release capsules for 7 days. Patients not responding to 75 mg per day may benefit from dose increases to a maximum of approximately 225 mg per day. Dose increases should be in increments of up to 75 mg per day, as needed, and should be made at intervals of not less than 7 days.

    2.6 Screen for Bipolar Disorder Prior to Starting Venlafaxine hydrochloride extended-release capsules

    Prior to initiating treatment with Venlafaxine hydrochloride extended-release capsules, screen patients for a personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions (5.6)]. 

    2.7 Switching Patients from Venlafaxine Hydrochloride Tablets

    Patients with depression who are currently being treated with venlafaxine hydrochloride tablets may be switched to Venlafaxine hydrochloride extended-release capsules at the nearest equivalent dose (mg per day), e.g., 37.5 mg venlafaxine twice a day to 75 mg Venlafaxine hydrochloride extended-release capsules once daily. However, individual dosage adjustments may be necessary.

    2.8 Dosage Recommendations for Patients with Hepatic Impairment

    Reduce the Venlafaxine hydrochloride extended-release capsules total daily dose by 50% in patients with mild (Child-Pugh Class A) to moderate (Child-Pugh Class B) hepatic impairment. Reduce the total daily dose by 50% or more in patients with severe hepatic impairment (Child-Pugh Class C) or hepatic cirrhosis [see Use in Specific Populations (8.6)].

    2.9 Dosage Recommendations for Patients with Renal Impairment

    Reduce the Venlafaxine hydrochloride extended-release capsules total daily dose by 25% to 50% in patients with mild (CLcr 60-89 mL/min) or moderate (CLcr 30-59 mL/min) renal impairment. Reduce the total daily dose by 50% or more in patients undergoing hemodialysis or with severe renal impairment (CLcr < 30 mL/min). Because there was much individual variability in clearance between patients with renal impairment, individualization of dosage is recommended in some patients [see Use in Specific Populations (8.7)].

    2.10 Discontinuing Treatment with Venlafaxine hydrochloride extended-release capsules

    A gradual reduction in the dose, rather than abrupt cessation, is recommended when discontinuing therapy with Venlafaxine hydrochloride extended-release capsules. In clinical studies with Venlafaxine hydrochloride extended-release capsules, tapering was achieved by reducing the daily dose by 75 mg at one-week intervals. Individualization of tapering may be necessary. In some patients, discontinuation may need to occur over a period of several months [see Warnings and Precautions (5.7)].

    2.11 Switching Patients to or from a Monoamine Oxidase Inhibitor (MAOI) Antidepressant

    At least 14 days must elapse between discontinuation of an MAOI antidepressant and initiation of Venlafaxine hydrochloride extended-release capsules. In addition, at least 7 days must elapse after stopping Venlafaxine hydrochloride extended-release capsules before starting an MAOI antidepressant [see Contraindications (4), Warnings and Precautions (5.2), and Drug Interactions (7.1)].

    Venlafaxine hydrochloride extended-release capsules is contraindicated in patients:

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Suicidal Thoughts and Behaviors in Adolescents, and Young Adults

    In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients and 4,500 pediatric patients, the incidence of suicidal thoughts and behaviors in antidepressant-treated patients age 24 years and younger was greater than in placebo-treated patients. There was considerable variation in risk of suicidal thoughts and behaviors among drugs, but there was an increased risk identified in young patients for most drugs studied. There were differences in absolute risk of suicidal thoughts and behaviors across the different indications, with the highest incidence in patients with MDD. The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1,000 patients treated are provided in Table 1.

    Table 1: Risk Differences of the Number of Patients of Suicidal Thoughts and Behaviors in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric* and Adult Patients
    *
    Venlafaxine hydrochloride extended-release capsules is not approved in pediatric patients.

    Age Range
    Drug-Placebo Difference in Number of Patients of Suicidal Thoughts and Behaviors per 1,000 Patients Treated
    Increases Compared to Placebo
    <18 years old
    14 additional patients
    18-24 years old
    5 additional patients

    Decreases Compared to Placebo
    25-64 years old
    1 fewer patient
    ≥65 years old
    6 fewer patients

    It is unknown whether risk of suicidal thoughts and behaviors in children, adolescents, and young adults extends to longer-term use, i.e., beyond four months. However, there is substantial evidence from placebo-controlled maintenance trials in adults with MDD that antidepressants delay the recurrence of depression and that depression itself is a risk factor for suicidal thoughts and behaviors.

    Monitor all antidepressant-treated patients for any indication for clinical worsening and emergence of suicidal thoughts and behaviors, especially during the initial few months of drug therapy, and at times of dosage changes. Counsel family members or caregivers of patients to monitor for changes in behavior and to alert the healthcare provider. Consider changing the therapeutic regimen, including possibly discontinuing Venlafaxine hydrochloride extended-release capsules, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.

    5.2 Serotonin Syndrome

    Serotonin-norepinephrine reuptake inhibitors (SNRIs), including Venlafaxine hydrochloride extended-release capsules, can precipitate serotonin syndrome, a potentially life-threatening condition. The risk is increased with concomitant use of other serotonergic drugs (including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, and St. John's wort) and with drugs that impair metabolism of serotonin particular, i.e., MAOIs [see Contraindications (4), Drug Interactions (7.1)]. Serotonin syndrome can also occur when these drugs are used alone.

    Serotonin syndrome signs and symptoms may include mental status changes (e.g., agitation, hallucinations, delirium, coma), autonomic instability (e.g., tachycardia, labile blood pressure, dizziness, diaphoresis, flushing, hyperthermia), neuromuscular symptoms (e.g., tremor, rigidity, myoclonus, hyperreflexia, incoordination);, seizures, and gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).

    The concomitant use of Venlafaxine hydrochloride extended-release capsules with MAOIs is contraindicated. In addition, do not initiate Venlafaxine hydrochloride extended-release capsules in a patient being treated with MAOIs such as linezolid or intravenous methylene blue. No reports involved the administration of methylene blue by other routes (such as oral tablets or local tissue injection). If it is necessary to initiate treatment with an MAOI such as linezolid or intravenous methylene blue in a patient taking Venlafaxine hydrochloride extended-release capsules, discontinue Venlafaxine hydrochloride extended-release capsules before initiating treatment with the MAOI [see Contraindications (4), Drug Interactions (7.1)].

    Monitor all patients taking Venlafaxine hydrochloride extended-release capsules for the emergence of serotonin syndrome. Discontinue treatment with Venlafaxine hydrochloride extended-release capsules and any concomitant serotonergic agents immediately if the above symptoms occur, and initiate supportive symptomatic treatment. If concomitant use of Venlafaxine hydrochloride extended-release capsules with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms.

    5.3 Elevated Blood Pressure

    In controlled trials, there were dose-related increases in systolic and diastolic blood pressure, as well as cases of sustained hypertension [see Adverse Reactions (6.1)].

    Monitor blood pressure before initiating treatment with Venlafaxine hydrochloride extended-release capsules and regularly during treatment. Control pre-existing hypertension before initiating treatment with Venlafaxine hydrochloride extended-release capsules. Use caution in treating patients with pre-existing hypertension or cardiovascular or cerebrovascular conditions that might be compromised by increases in blood pressure. Sustained blood pressure elevation can lead to adverse outcomes. Cases of elevated blood pressure requiring immediate treatment have been reported with Venlafaxine hydrochloride extended-release capsules. Consider dose reduction or discontinuation of treatment for patients who experience a sustained increase in blood pressure.

    Across all clinical studies with venlafaxine hydrochloride tablets, 1.4% of patients in the Venlafaxine hydrochloride extended-release capsules treated groups experienced a ≥15 mm Hg increase in supine diastolic blood pressure (SDBP) ≥105 mm Hg, compared to 0.9% of patients in the placebo groups. Similarly, 1% of patients in the Venlafaxine hydrochloride extended-release capsules treated groups experienced a ≥20 mm Hg increase in supine systolic blood pressure (SSBP) with blood pressure ≥180 mm Hg, compared to 0.3% of patients in the placebo groups [see Table 10 in Adverse Reactions (6.1)]. Treatment with Venlafaxine hydrochloride extended-release capsules was associated with sustained hypertension (defined as treatment-emergent SDBP ≥90 mm Hg and ≥10 mm Hg above baseline for three consecutive on-therapy visits [see Adverse Reactions (6.1)]. An insufficient number of patients received mean doses of venlafaxine hydrochloride extended-release capsule over 300 mg per day in clinical studies to fully evaluate the incidence of sustained increases in blood pressure at these higher doses.

    5.4 Increased Risk of Bleeding

    Drugs that interfere with serotonin reuptake inhibition, including venlafaxine hydrochloride extended-release capsule, may increase the risk of bleeding events, ranging from ecchymoses, hematomas, epistaxis, petechiae, and gastrointestinal hemorrhage to life-threatening hemorrhage. Concomitant use of aspirin, Nonsteroidal Anti-Inflammatory Drugs (NSAIDs), warfarin, and other anti-coagulants or other drugs known to affect platelet function may add to this risk. Case reports and epidemiological studies (case-control and cohort design) have demonstrated an association between use of drugs that interfere with serotonin reuptake and the occurrence of gastrointestinal bleeding.

    Inform patients about the risk of bleeding associated with the concomitant use of venlafaxine hydrochloride extended-release capsule and nonsteroidal anti-inflammatory drugs (NSAIDs), aspirin, or other drugs that affect coagulation. For patients taking warfarin, carefully monitor coagulation indices when initiating, titrating, or discontinuing venlafaxine hydrochloride extended-release capsule.

    5.5 Angle-Closure Glaucoma

    The pupillary dilation that occurs following use of many antidepressant drugs including Venlafaxine hydrochloride extended-release capsules may trigger an angle closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy. Avoid use of antidepressants, including venlafaxine hydrochloride extended-release capsule, in patients with untreated anatomically narrow angles.

    5.6 Activation of Mania or Hypomania

    In patients with bipolar disorder, treating a depressive episode with Venlafaxine hydrochloride extended-release capsules or another antidepressant may precipitate a mixed/manic episode. Mania or hypomania was reported in Venlafaxine hydrochloride extended-release capsules treated patients in the premarketing studies in MDD, SAD, and PD (see Table 2). Prior to initiating treatment with Venlafaxine hydrochloride extended-release capsules, screen for any personal or family history of bipolar disorder, mania, or hypomania.

    5.7 Discontinuation Syndrome

    Discontinuation symptoms have been systematically evaluated in patients taking venlafaxine, including prospective analyses of clinical studies in GAD and retrospective surveys of studies in MDD and SAD. Abrupt discontinuation or dose reduction of venlafaxine at various doses has been found to be associated with the appearance of new symptoms, the frequency of which increased with increased dose level and with longer duration of treatment. Reported symptoms include agitation, anorexia, anxiety, confusion, impaired coordination and balance, diarrhea, dizziness, dry mouth, dysphoric mood, fasciculation, fatigue, flu-like symptoms, headaches, hypomania, insomnia, nausea, nervousness, nightmares, sensory disturbances (including shock-like electrical sensations), somnolence, sweating, tremor, vertigo, and vomiting.

    There have been postmarketing reports of serious discontinuation symptoms which can be protracted and severe. Completed suicide, suicidal thoughts, aggression and violent behavior have been observed in patients during reduction in Venlafaxine hydrochloride extended-release capsules dosage, including during discontinuation. Other postmarketing reports describe visual changes (such as blurred vision or trouble focusing) and increased blood pressure after stopping or reducing the dose of Venlafaxine hydrochloride extended-release capsules.

    During marketing of Venlafaxine hydrochloride extended-release capsules, other SNRIs, and SSRIs, there have been reports of adverse events occurring upon discontinuation of these drugs, particularly when abrupt, including the following: irritability, lethargy, emotional lability, tinnitus, and seizures.

    Patients should be monitored for these symptoms when discontinuing treatment with Venlafaxine hydrochloride extended-release capsules. A gradual reduction in the dose, rather than abrupt cessation, is recommended. If intolerable symptoms occur following a decrease in the dose or upon discontinuation of treatment, then resuming the previously prescribed dose may be considered. Subsequently, the healthcare provider may continue decreasing the dose, but at a more gradual rate. In some patients, discontinuation may need to occur over a period of several months. [see Dosage and Administration (2.10)].

    5.8 Seizures

    Cases of seizure have been reported with venlafaxine therapy. Venlafaxine hydrochloride extended-release capsules has not been systematically evaluated in patients with seizure disorder. Venlafaxine hydrochloride extended-release capsules should be prescribed with caution in patients with a seizure disorder.

    5.9 Hyponatremia

    Hyponatremia can occur as a result of treatment with SNRIs, including Venlafaxine hydrochloride extended-release capsules. In many cases, the hyponatremia appears to be the result of the Syndrome of Inappropriate Antidiuretic Hormone (SIADH) secretion. Cases with serum sodium lower than 110 mmol/L have been reported. Elderly patients may be at greater risk of developing hyponatremia with SNRIs. Also, patients taking diuretics, or those who are otherwise volume-depleted, may be at greater risk [see Use in Specific Populations (8.5) and Clinical Pharmacology (12.3)]. Consider discontinuation of Venlafaxine hydrochloride extended-release capsules in patients with symptomatic hyponatremia, and institute appropriate medical intervention.

    Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which may lead to falls. Signs and symptoms associated with more severe and/or acute cases have included hallucination, syncope, seizure, coma, respiratory arrest, and death.

    5.10 Weight and Height Changes in Pediatric Patients

    Weight Changes                                  

    The average change in body weight and incidence of weight loss (percentage of patients who lost 3.5% or more) in the placebo-controlled pediatric studies in MDD, GAD, and SAD are shown in Tables 3 and 4.

    Weight loss was not limited to patients with anorexia [see Warnings and Precautions (5.11)].

    The risks associated with longer term Venlafaxine hydrochloride extended-release capsules use were assessed in an open-label MDD study of children and adolescents who received Venlafaxine hydrochloride extended-release capsules for up to six months. The children and adolescents in the study had increases in weight that were less than expected, based on data from age-and sex-matched peers. The difference between observed weight gain and expected weight gain was larger for children (<12 years old) than for adolescents (≥12 years old).

    Height Changes

    Table 5 shows the average height increase in pediatric patients in the short-term, placebo-controlled MDD, GAD, and SAD studies. The differences in height increases in GAD and MDD studies were most notable in patients younger than 12 years old.

    In the six-month, open-label MDD study, children and adolescents had height increases that were less than expected, based on data from age-and sex-matched peers. The difference between observed and expected growth rates was larger for children (<12 years old) than for adolescents (≥12 years old) [see Use in Specific Populations (8.4)].

    5.11 Appetite Changes in Pediatric Patients

    Decreased appetite (reported as anorexia) was more commonly observed in Venlafaxine hydrochloride extended-release capsules treated patients versus placebo-treated patients in the premarketing evaluation of Venlafaxine hydrochloride extended-release capsules for MDD, GAD, and SAD (see Table 6).

    Venlafaxine hydrochloride extended-release capsules is not approved for use in pediatric patients [see Use in Specific Populations (8.4)].

    5.12 Interstitial Lung Disease and Eosinophilic Pneumonia

    Interstitial lung disease and eosinophilic pneumonia associated with venlafaxine therapy have been rarely reported. The possibility of these events should be considered in venlafaxine-treated patients who present with progressive dyspnea, cough or chest discomfort. Such patients should undergo a prompt medical evaluation, and discontinuation of venlafaxine hydrochloride extended-release should be considered.

    5.13 Sexual Dysfunction

    Use of SNRIs, including Venlafaxine hydrochloride extended-release capsules, may cause symptoms of sexual dysfunction [see Adverse Reactions (6.1)]. In male patients, SNRI use may result in ejaculatory delay or failure, decreased libido, and erectile dysfunction. In female patients, SNRI use may result in decreased libido and delayed or absent orgasm. It is important for prescribers to inquire about sexual function prior to initiation of Venlafaxine hydrochloride extended-release capsules and to inquire specifically about changes in sexual function during treatment, because sexual function may not be spontaneously reported. When evaluating changes in sexual function, obtaining a detailed history (including timing of symptom onset) is important because sexual symptoms may have other causes, including the underlying psychiatric disorder. Discuss potential management strategies to support patients in making informed decisions about treatment.

  • 6 ADVERSE REACTIONS

    The following adverse reactions are discussed in more detail in other sections of the labeling:

    6.1 Clinical Studies Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in clinical practice.

    Most Common Adverse Reactions

    The most commonly observed adverse reactions in the clinical study database in Venlafaxine hydrochloride extended-release capsules treated patients in MDD, GAD, SAD, and PD (incidence ≥5% and at least twice the rate of placebo) were: nausea (30.0%), somnolence (15.3%), dry mouth (14.8%), sweating (11.4%), abnormal ejaculation (9.9%), anorexia (9.8%), constipation (9.3%), impotence (5.3%) and decreased libido (5.1%).

    Adverse Reactions Reported as Reasons for Discontinuation of Treatment

    Combined across short-term, placebo-controlled premarketing studies for all indications, 12% of the 3,558 patients who received Venlafaxine hydrochloride extended-release capsules (37.5-225 mg) discontinued treatment due to an adverse experience, compared with 4% of the 2,197 placebo-treated patients in those studies.

    The most common adverse reactions leading to discontinuation in ≥1% of the Venlafaxine hydrochloride extended-release capsules treated patients in the short-term studies (up to 12 weeks) across indications are shown in Table 7.

    Common Adverse Reactions in Placebo-controlled Studies

    The number of patients receiving multiple doses of Venlafaxine hydrochloride extended-release capsules during the premarketing assessment for each approved indication is shown in Table 8. The conditions and duration of exposure to venlafaxine in all development programs varied greatly, and included (in overlapping categories) open and double-blind studies, uncontrolled and controlled studies, inpatient (venlafaxine hydrochloride tablets only) and outpatient studies, fixed-dose, and titration studies.

    Table 8: Patients Receiving Venlafaxine Hydrochloride Extended-release Capsulesin Premarketing Clinical Studies

    Vital Sign Changes

    In placebo-controlled premarketing studies, there were increases in mean blood pressure (see Table 10). Across most indications, a dose-related increase in mean supine systolic and diastolic blood pressure was evident in patients treated with Venlafaxine hydrochloride extended-release capsules. Across all clinical studies in MDD, GAD, SAD and PD, 1.4% of patients in the Venlafaxine hydrochloride extended-release capsules groups experienced an increase in SDBP of ≥15 mm Hg along with a blood pressure ≥105 mm Hg, compared to 0.9% of patients in the placebo groups. Similarly, 1% of patients in the Venlafaxine hydrochloride extended-release capsules groups experienced an increase in SSBP of ≥20 mm Hg with a blood pressure ≥180 mm Hg, compared to 0.3% of patients in the placebo groups.

    Venlafaxine hydrochloride extended-release capsules treatment for up to 12 weeks in premarketing placebo-controlled trials for major depressive disorder was associated with a mean final on-therapy increase in serum cholesterol concentration of approximately 1.5 mg/dL compared with a mean final decrease of 7.4 mg/dL for placebo. Venlafaxine hydrochloride extended-release capsules treatment for up to 8 weeks and up to 6 months in premarketing placebo-controlled GAD trials was associated with mean final on-therapy increases in serum cholesterol concentration of approximately 1.0 mg/dL and 2.3 mg/dL, respectively while placebo subjects experienced mean final decreases of 4.9 mg/dL and 7.7 mg/dL, respectively. Venlafaxine hydrochloride extended-release capsules treatment for up to 12 weeks and up to 6 months in premarketing placebo-controlled Social Anxiety Disorder trials was associated with mean final on-therapy increases in serum cholesterol concentration of approximately 7.9 mg/dL and 5.6 mg/dL, respectively, compared with mean final decreases of 2.9 and 4.2 mg/dL, respectively, for placebo. Venlafaxine hydrochloride extended-release capsules treatment for up to 12 weeks in premarketing placebo-controlled panic disorder trials was associated with mean final on-therapy increases in serum cholesterol concentration of approximately 5.8 mg/dL compared with a mean final decrease of 3.7 mg/dL for placebo.

    Patients treated with venlafaxine hydrochloride tablets (immediate release) for at least 3 months in placebo-controlled 12-month extension trials had a mean final on-therapy increase in total cholesterol of 9.1 mg/dL compared with a decrease of 7.1 mg/dL among placebo-treated patients. This increase was duration dependent over the study period and tended to be greater with higher doses. Clinically relevant increases in serum cholesterol, defined as 1) a final on-therapy increase in serum cholesterol ≥50 mg/dL from baseline and to a value ≥261 mg/dL, or 2) an average on-therapy increase in serum cholesterol ≥50 mg/dL from baseline and to a value ≥261 mg/dL, were recorded in 5.3% of venlafaxine-treated patients and 0.0% of placebo-treated patients.

    Serum Triglycerides

    6.2 Postmarketing Experience

    The following adverse reactions have been identified during postapproval use of Venlafaxine hydrochloride extended-release capsules. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

    Body as a whole – Anaphylaxis, angioedema

    Cardiovascular system – QT prolongation, ventricular fibrillation, ventricular tachycardia (including torsade de pointes), takotsubo cardiomyopathy

    Digestive system – Pancreatitis

    Image

    7.1 Drugs Having Clinically Important Interactions with Venlafaxine hydrochloride extended-release capsules

    Table 15: Clinically Important Drug Interactions with Venlafaxine hydrochloride extended-release capsules
    Monoamine Oxidase Inhibitors (MAOI)
    Clinical Impact
    The concomitant use of SNRIs, including Venlafaxine hydrochloride extended-release capsules, with MAOIs increases the risk of serotonin syndrome.
    Intervention
    Concomitant use of Venlafaxine hydrochloride extended-release capsules is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue [see Dosage and Administration (2.11), Contraindications (4) and Warnings and Precautions (5.2)]
    Other Serotonergic Drugs
    Clinical Impact
    Concomitant use of Venlafaxine hydrochloride extended-release capsules with other serotonergic drugs increases the risk of serotonin syndrome.
    Intervention
    Monitor for symptoms of serotonin syndrome when Venlafaxine hydrochloride extended-release capsules is used concomitantly with other drugs that may affect the serotonergic neurotransmitter systems. If serotonin syndrome occurs, consider discontinuation of Venlafaxine hydrochloride extended-release capsules and/or concomitant serotonergic drugs [see Dosage and Administration (2.11) and Warnings and Precautions (5.2)].
    Drugs that Interfere with Hemostasis
    Clinical Impact
    Concomitant use of Venlafaxine hydrochloride extended-release capsules with an antiplatelet or anticoagulant drug may potentiate the risk of bleeding. This may be due to the effect of Venlafaxine hydrochloride extended-release capsules on the release of serotonin by platelets.
    Intervention
    Closely monitor for bleeding for patients receiving an antiplatelet or anticoagulant drug when Venlafaxine hydrochloride extended-release capsules is initiated or discontinued [see Warnings and Precautions (5.4)] .
    Effect of CYP3A Inhibitors
    Clinical Impact
    Concomitant use of a CYP3A inhibitor increases the Cmax and AUC of venlafaxine and O-desmethylvenlafaxine (ODV) [see Clinical Pharmacology (12.3)] , which may increase the risk of toxicity of Venlafaxine hydrochloride extended-release capsules
    Intervention
    Consider reducing the dose of Venlafaxine hydrochloride extended-release capsules.
    CYP2D6 Substrates
    Clinical Impact
    Concomitant use of Venlafaxine hydrochloride extended-release capsules increases Cmax and AUC of a CYP2D6 substrate, which may increase the risk of toxicity of the CYP2D6 substrate [see Clinical Pharmacology (12.3)] .
    Intervention
    Consider reduction in dose of concomitant CYP2D6 substrates.

    7.2 Other Drug Interactions with Venlafaxine hydrochloride extended-release capsules

    Central Nervous System (CNS)-Active Drugs

    The risk of using venlafaxine concomitantly with other CNS-active drugs (including alcohol) has not been systematically evaluated. Consequently, caution is advised when Venlafaxine hydrochloride extended-release capsules is taken concomitantly in combination with other CNS-active drugs.

    Weight Loss Agents

    Concomitant use of Venlafaxine hydrochloride extended-release capsules and weight loss agents is not recommended. The safety and efficacy of venlafaxine therapy in combination with weight loss agents, including phentermine, have not been established. Venlafaxine hydrochloride extended-release capsules is not indicated for weight loss alone or in combination with other products.

    Laboratory Test Interference

    False-positive urine immunoassay screening tests for phencyclidine (PCP) and amphetamine have been reported in patients taking venlafaxine due to lack of specificity of the screening tests. False positive test results may be expected for several days following discontinuation of venlafaxine therapy. Confirmatory tests, such as gas chromatography/mass spectrometry, will distinguish venlafaxine from PCP and amphetamine.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Pregnancy Exposure Registry

    There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to antidepressants, including Venlafaxine hydrochloride extended-release capsules, during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Antidepressants at 1-844-405-6185 or visiting online at https://womensmentalhealth.org/clinical-and-researchprograms/ pregnancyregistry/antidepressants/.

    Risk Summary

    Available data from published epidemiologic studies on venlafaxine use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage or adverse fetal outcomes (see Data). Available data from observational studies with venlafaxine have identified a potential increased risk for preeclampsia when used during mid to late pregnancy; exposure to SNRIs near delivery may increase the risk for postpartum hemorrhage (see Clinical Considerations). There are risks associated with untreated depression in pregnancy and poor neonatal adaptation in newborns with exposure to SNRIs, including Venlafaxine hydrochloride extended-release capsules, during pregnancy (see Clinical Considerations).

    In animal studies, there was no evidence of malformations or fetotoxicity following administration of venlafaxine during organogenesis at doses up to 2.5 times (rat) or 4 times (rabbit) the maximum recommended human daily dose on a mg/m2 basis. Postnatal mortality and decreased pup weights were observed following venlafaxine administration to pregnant rats during gestation and lactation at 2.5 times (mg/m2) the maximum human daily dose.

    The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

    Clinical Considerations

    Disease-Associated Maternal and/or Embryo/Fetal Risk

    Women who discontinue antidepressants during pregnancy are more likely to experience a relapse of major depression than women who continue antidepressants. This finding is from a prospective, longitudinal study that followed 201 pregnant women with a history of major depression who were euthymic and taking antidepressants at the beginning of pregnancy. Consider the risk of untreated depression when discontinuing or changing treatment with antidepressant medication during pregnancy and postpartum.

    Maternal Adverse Reactions

    Exposure to venlafaxine in mid to late pregnancy may increase the risk for preeclampsia, and exposure to SNRIs near delivery may increase the risk for postpartum hemorrhage.

    Fetal/Neonatal Adverse Reactions

    Neonates exposed to SNRIs late in the third trimester have developed complications requiring prolonged hospitalization, respiratory support, and tube feeding. Such complications can arise immediately upon delivery. Reported clinical findings have included respiratory distress, cyanosis, apnea, seizures, temperature instability, feeding difficulty, vomiting, hypoglycemia, hypotonia, hypertonia, hyperreflexia, tremors, jitteriness, irritability, and constant crying. These findings are consistent with either a direct toxic effect of SNRIs or possibly a drug discontinuation syndrome. It should be noted that, in some cases, the clinical picture is consistent with serotonin syndrome [see Warnings and Precautions (5.2)]. Monitor neonates who were exposed to Venlafaxine hydrochloride extended-release capsules in the third trimester of pregnancy for drug discontinuation syndrome (see Data).

    Data

    Human Data

    Published epidemiological studies of pregnant women exposed to venlafaxine have not established an increased risk of major birth defects, miscarriage or other adverse developmental outcomes.

    Methodological limitations may both fail to identify true findings and also identify findings that are not true.

    Retrospective cohort studies based on claims data have shown an association between venlafaxine use and preeclampsia, compared to depressed women who did not take an antidepressant during pregnancy. One study that assessed venlafaxine exposure in the second trimester or first half of the third trimester and preeclampsia showed an increased risk compared to unexposed depressed women (adjusted [adj] RR 1.57, 95% confidence interval [CI] 1.29-1.91). Preeclampsia was observed at venlafaxine doses equal to or greater than 75 mg per day and a duration of treatment >30 days. Another study that assessed venlafaxine exposure in gestational weeks 10-20 and preeclampsia showed an increased risk at doses equal to or greater than 150 mg per day. Available data are limited by possible outcome misclassification and possible confounding due to depression severity and other confounders.

    Retrospective cohort studies based on claims data have suggested an association between venlafaxine use near the time of delivery or through delivery and postpartum hemorrhage. One study showed an increased risk for postpartum hemorrhage when venlafaxine exposure occurred through delivery, compared to unexposed depressed women (adj RR 2.24 [95% CI 1.69-2.97]). There was no increased risk in women who were exposed to venlafaxine earlier in pregnancy. Limitations of this study include possible confounding due to depression severity and other confounders. Another study showed an increased risk for postpartum hemorrhage when SNRI exposure occurred for at least 15 days in in the last month of pregnancy or through delivery, compared to unexposed women (adj RR 1.64-1.76). The results of this study may be confounded by the effects of depression.

    Animal Data

    Venlafaxine did not cause malformations in offspring of rats or rabbits given doses up to 2.5 times (rat) or 4 times (rabbit) the maximum recommended human daily dose on a mg/m2 basis. However, in rats, there was a decrease in pup weight, an increase in stillborn pups, and an increase in pup deaths during the first 5 days of lactation, when dosing began during pregnancy and continued until weaning. The cause of these deaths is not known. These effects occurred at 2.5 times (mg/m2) the maximum human daily dose. The no effect dose for rat pup mortality was 0.25 times the human dose on a mg/m2 basis.

    When desvenlafaxine succinate, the major metabolite of venlafaxine, was administered orally to pregnant rats and rabbits during the period of organogenesis at doses up to 300 mg/kg/day and 75 mg/kg/day, respectively, no fetal malformations were observed. These doses were associated with a plasma exposure (AUC) 19 times (rats) and 0.5 times (rabbits) the AUC exposure at an adult human dose of 100 mg per day. However, fetal weights were decreased and skeletal ossification was delayed in rats in association with maternal toxicity at the highest dose, with an AUC exposure at the no-effect dose that is 4.5-times the AUC exposure at an adult human dose of 100 mg per day.

    8.2 Lactation

    Risk Summary

    Data from published literature report the presence of venlafaxine and its active metabolite in human milk and have not shown adverse reactions in breastfed infants (see Data). There are no data on the effects of venlafaxine on milk production.

    The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Venlafaxine hydrochloride extended-release capsules and any potential adverse effects on the breastfed child from Venlafaxine hydrochloride extended-release capsules or from the underlying maternal condition.

    Data

    In a lactation study conducted in 11 breastfeeding women (at a mean of 20.1 months post-partum) who were taking a mean daily dose of 194.3 mg of venlafaxine and in a lactation study conducted in 6 breastfeeding women who were taking a daily dose of 225 mg to 300 mg of venlafaxine (at a mean of 7 months post-partum), the estimated mean relative infant dose was 8.1 % and 6.4% based on the sum of  venlafaxine and its major metabolite, desvenlafaxine. No adverse reactions were seen in the infants.

    8.4 Pediatric Use

    Safety and effectiveness of Venlafaxine hydrochloride extended-release capsules in pediatric patients have not been established.

    Two placebo-controlled trials in 766 pediatric patients with MDD and two placebo-controlled trials in 793 pediatric patients with GAD have been conducted with Venlafaxine hydrochloride extended-release capsules, and the data were not sufficient to support use in pediatric patients.

    In the studies conducted in pediatric patients ages 6 to17 years, the occurrence of blood pressure and cholesterol increases was considered to be clinically relevant in pediatric patients and was similar to that observed in adult patients [see Warnings and Precautions (5.3), Adverse Reactions (6.1)]. The following adverse reactions were also observed in pediatric patients: abdominal pain, agitation, dyspepsia, ecchymosis, epistaxis, and myalgia.

    Although no studies have been designed to primarily assess Venlafaxine hydrochloride extended-release capsules's impact on the growth,

    development, and maturation of children and adolescents, the studies that have been done suggest that Venlafaxine hydrochloride extended-release capsules may adversely affect weight and height

    [see Warnings and Precautions (5.10, 5.11)].

    Decreased appetite and weight loss were observed in placebo-controlled studies of pediatric patients 6 to 17 years.

    In pediatric clinical studies, the adverse reaction, suicidal ideation, was observed. Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric patients [see Boxed Warning, Warnings and Precautions (5.1)].

    8.5 Geriatric Use

    The percentage of patients in clinical studies for Venlafaxine hydrochloride extended-release capsules for MDD, GAD, SAD, and PD who were 65 years of age or older are shown in Table 16.

    Table 16: Percentage (and Number of Patients Studied) of Patients 65 Years of Age and Older by Indicationa

    aIn addition, in the premarketing assessment of venlafaxine hydrochloride (immediate release), 12% (357/2,897) of patients were ≥65 years of age.

    Indication

    4 (14/357)
    6 (77/1,381)
    1 (10/819)
    2 (16/1,001)

    No overall differences in effectiveness or safety were observed between geriatric patients and younger patients, and other reported clinical experience generally has not identified differences in response between the elderly and younger patients. However, greater sensitivity of some older individuals cannot be ruled out. SSRIs and SNRIs, including Venlafaxine hydrochloride extended-release capsules, have been associated with cases of clinically significant hyponatremia in elderly patients, who may be at greater risk for this adverse event [see Warnings and Precautions (5.9)].

    The pharmacokinetics of venlafaxine and ODV are not substantially altered in the elderly [see Clinical Pharmacology (12.3) (see Figure 1)]. No dose adjustment is recommended for the elderly on the basis of age alone, although other clinical circumstances, some of which may be more common in the elderly, such as renal or hepatic impairment, may warrant a dose reduction [see Dosage and Administration (2.8, 2.9)]. 

    8.6 Hepatic Impairment

    Dosage adjustment is recommended in patients with mild (Child-Pugh Class A), moderate (Child-Pugh Class B), or severe (Child-Pugh Class C) hepatic impairment or hepatic cirrhosis [see Dosage and Administration (2.8) and Clinical Pharmacology (12.3)].

    8.7 Renal Impairment

    Dosage adjustment is recommended in patients with mild (CLcr= 60-89 mL/min), moderate (CLcr= 30-59 mL/min), or severe (CLcr < 30 mL/min) renal impairment, and in patients undergoing hemodialysis [see Dosage and Administration (2.9) and Clinical Pharmacology (12.3)].

  • 9 DRUG ABUSE AND DEPENDENCE

    9.1 Controlled Substance

    Venlafaxine hydrochloride extended-release capsules contains venlafaxine which is not a controlled substance.

    9.2 Abuse

    Abuse is the intentional, non-therapeutic use of a drug, even once, for its desirable psychological or physiological effects.

    While venlafaxine has not been systematically studied in clinical studies for its potential for abuse, there was no indication of drug-seeking behavior in the clinical studies. However, it is not possible to predict on the basis of premarketing experience the extent to which a CNS-active drug will be misused, diverted, and/or abused once marketed. Consequently, providers should carefully evaluate patients for history of drug abuse and follow such patients closely, observing them for signs of misuse or abuse of venlafaxine (e.g., development of tolerance, incrementation of dose, drug-seeking behavior).

    9.3 Dependence

    Physical dependence is a state that develops as a result of physiological adaptation in response to repeated drug use, manifested by withdrawal signs and symptoms after abrupt discontinuation or a significant dose reduction of a drug.

    In vitro studies revealed that venlafaxine has virtually no affinity for opiate, benzodiazepine, phencyclidine (PCP), or N-methyl-D-aspartic acid (NMDA) receptors.

    Venlafaxine was not found to have any significant CNS stimulant activity in rodents. In primate drug discrimination studies, venlafaxine showed no significant stimulant or depressant abuse liability. Discontinuation effects have been reported in patients receiving venlafaxine [see Dosage and Administration (2.10) and Warnings and Precautions (5.7)]. 

  • 10 OVERDOSAGE

    Human Experience

    During the premarketing evaluations of Venlafaxine hydrochloride extended-release capsules  for MDD, GAD, SAD, and PD) and venlafaxine hydrochloride tablets (for MDD), there were twenty reports of acute overdosage with venlafaxine hydrochloride tablets (6 and 14 reports in Venlafaxine hydrochloride extended-release capsules and venlafaxine hydrochloride tablets patients, respectively), either alone or in combination with other drugs and/or alcohol.

    Somnolence was the most commonly reported symptom. Among the other reported symptoms were paresthesia of all four limbs, moderate dizziness, nausea, numb hands and feet, and hot-cold spells 5 days after the overdose. In most cases, no signs or symptoms were associated with overdose. The majority of the reports involved ingestion in which the total dose of venlafaxine taken was estimated to be no more than several-fold higher than the usual therapeutic dose. One patient who ingested 2.75 g of venlafaxine was observed to have two generalized convulsions and a prolongation of QTc to 500 msec, compared with 405 msec at baseline. Mild sinus tachycardia was reported in two of the other patients.

    Actions taken to treat the overdose included no treatment, hospitalization and symptomatic treatment, and hospitalization plus treatment with activated charcoal. All patients recovered.

    In postmarketing experience, overdose with venlafaxine has occurred predominantly in combination with alcohol and/or other drugs. The most commonly reported events in overdosage include tachycardia, changes in level of consciousness (ranging from somnolence to coma), mydriasis, seizures, and vomiting. Electrocardiogram changes (e.g., prolongation of QT interval, bundle branch block, QRS prolongation), ventricular tachycardia, bradycardia, hypotension, rhabdomyolysis, vertigo, liver necrosis, serotonin syndrome, and death have been reported.

    Published retrospective studies report that venlafaxine overdosage may be associated with an increased risk of fatal outcomes compared to that observed with SSRI antidepressant products, but lower than that for tricyclic antidepressants. Epidemiological studies have shown that venlafaxine-treated patients have a higher preexisting burden of suicide risk factors than SSRI-treated patients. The extent to which the finding of an increased risk of fatal outcomes can be attributed to the toxicity of venlafaxine in overdosage, as opposed to some characteristic(s) of venlafaxine-treated patients, is not clear. Prescriptions for Venlafaxine hydrochloride extended-release capsules should be written for the smallest quantity of capsules consistent with good patient management, in order to reduce the risk of overdose.

    Management of Overdosage

    No specific antidotes for Venlafaxine hydrochloride extended-release capsules are known. In managing overdosage, consider the possibility of multiple drug involvement. Consider contacting a Poison Center (1-800-222-1222) or a medical toxicologist for overdosage management recommendations for Venlafaxine hydrochloride extended-release capsules.

  • 11 DESCRIPTION

    Venlafaxine hydrochloride extended-release capsules, USP is an extended-release capsule for once-a-day oral administration that contains venlafaxine hydrochloride, a serotonin and norepinephrine reuptake inhibitor (SNRI).

    Venlafaxine is designated (R/S)-1-[2-(dimethylamino)-1-(4-methoxyphenyl)ethyl] cyclohexanol hydrochloride or (±)-1-[α-[(dimethylamino)methyl]-p-methoxybenzyl] cyclohexanol hydrochloride and has the empirical formula of C17H27NO2 HCl. Its molecular weight is 313.86. The structural formula is shown as follows:

    Image

    Venlafaxine hydrochloride is a white to off-white crystalline solid, with a solubility of 572 mg/mL in water (adjusted to ionic strength of 0.2 M with sodium chloride). Its octanol:water(0.2 M sodium chloride) partition coefficient is 0.43.

The 150 mg capsules also contain iron oxide red and iron oxide yellow.

    The 37.5 mg, 75 mg and 150 mg capsules are imprinted with black and grey ink which contains iron black oxide, butyl alcohol, dehydrated alcohol, isopropyl alcohol, potassium hydroxide, propylene glycol, purified water, shellac and strong ammonia solution. Grey ink also contains titanium dioxide.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    The mechanism of action of venlafaxine the treatment of MDD, GAD, SAD, and PD is unclear, but is thought to be related to the potentiation of serotonin and norepinephrine in the central nervous system, through inhibition of their reuptake.

    12.2 Pharmacodynamics

    In-vitro studies have demonstrated that venlafaxine and its active metabolite, O-desmethylvenlafaxine (ODV), are potent and selective inhibitors of neuronal serotonin and norepinephrine reuptake and weak inhibitors of dopamine reuptake. Venlafaxine and ODV have no significant affinity for muscarinic-cholinergic, H1-histaminergic, or α1-adrenergic receptors in vitro. Pharmacologic activity at these receptors is hypothesized to be associated with the various anticholinergic, sedative, and cardiovascular effects seen with other psychotropic drugs. Venlafaxine and ODV do not possess monoamine oxidase (MAO) inhibitory activity.

    Cardiac Electrophysiology

    The effect of venlafaxine on the QT interval was evaluated in a randomized, double-blind, placebo- and positive-controlled three-period crossover thorough QT study in 54 healthy adult subjects. No significant. QT prolongation effect of venlafaxine at 450 mg (2 times the maximum recommended dosage) was detected.

    12.3 Pharmacokinetics

    Venlafaxine and ODV steady-state concentrations are reached within 3 days. Venlafaxine and ODV exhibited linear kinetics over the dosage range of 75 to 450 mg per day (0.33 to 2 times the maximum recommended dosage). Time of administration (AM versus PM) did not affect the pharmacokinetics of venlafaxine and ODV from the 75 mg Venlafaxine hydrochloride extended-release capsules capsule.

    Absorption

    Venlafaxine is well absorbed

    On the basis of mass balance studies, at least 92% of a single oral dose of venlafaxine is absorbed. The absolute bioavailability of venlafaxine is approximately 45%.

    Administration of Venlafaxine hydrochloride extended-release capsules (150 mg once daily) generally resulted in lower Cmax and later Tmax values than for venlafaxine hydrochloride tablets administered twice daily (Table 17). When equal daily doses of venlafaxine were administered as either an immediate-release tablet or the extended-release capsule, the exposure to both venlafaxine and ODV was similar for the two treatments, and the fluctuation in plasma concentrations was slightly lower with the Venlafaxine hydrochloride extended-release capsules. Therefore, Venlafaxine hydrochloride extended-release capsules provides a slower rate of absorption, but the same extent of absorption compared with the immediate-release tablet.

    Effect of Food

    Food did not affect the bioavailability of venlafaxine or its active metabolite, ODV

    Distribution

    Venlafaxine is 27% and ODV is 30% bound to plasma proteins. The apparent volume of distribution at steady-state is 7.5 ± 3.7 L/kg for venlafaxine and 5.7 ± 1.8 L/kg for ODV.

    Elimination

    Mean ± SD plasma apparent clearance at steady-state is 1.3 ± 0.6 L/h/kg for venlafaxine and

    0.4 ± 0.2 L/h/kg for ODV. The apparent elimination half-life is 5 ± 2 hours for venlafaxine and 11 ± 2 hours for ODV.

    Metabolism

    Following absorption, venlafaxine undergoes extensive presystemic metabolism in the liver, primarily to ODV, but also to N-desmethylvenlafaxine, N,O-didesmethylvenlafaxine, and other minor metabolites. In vitro studies indicate that the formation of ODV is catalyzed by CYP2D6; this has been confirmed in a clinical study showing that patients with low CYP2D6 levels (poor metabolizers) had increased levels of venlafaxine and reduced levels of ODV compared to people with normal CYP2D6 levels (extensive metabolizers) (see Figure 1).

    Excretion

    Approximately 87% of a venlafaxine dose is recovered in the urine within 48 hours as unchanged venlafaxine (5%), unconjugated ODV (29%), conjugated ODV (26%), or other minor inactive metabolites (27%).

    Specific Populations

    The effect of intrinsic patient factors on the pharmacokinetics of venlafaxine and its active metabolite ODV is presented in Figure 1.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenesis

    Tumors were not increased by venlafaxine treatment in mice or rats. Venlafaxine was given by oral gavage to mice for 18 months at doses up to 120 mg/kg per day, which was 1.7 times the maximum recommended human dose on a mg/m2basis. Venlafaxine was also given to rats by oral gavage for 24 months at doses up to 120 mg/kg per day. In rats receiving the 120 mg/kg dose, plasma concentrations of venlafaxine at necropsy were 1 times (male rats) and 6 times (female rats) the plasma concentrations of patients receiving the maximum recommended human dose. Plasma levels of the ODV were lower in rats than in patients receiving the maximum recommended dose. ODV, the major human metabolite of venlafaxine, administered by oral gavage to mice and rats for 2 years did not increase the incidence of tumors in either study. Mice received ODV at dosages up to 500/300 mg/kg/day (dosage lowered after 45 weeks of dosing). The exposure at the 300 mg/kg/day dose is 9 times that of a human dose of 225 mg/day. Rats received ODV at dosages up to 300 mg/kg/day (males) or 500 mg/kg/day (females). The exposure at the highest dose is approximately 8 (males) or 11 (females) times that of a human dose of 225 mg/day.

    Mutagenesis

    Venlafaxine and the major human metabolite, ODV, were not mutagenic in the Ames reverse mutation assay in Salmonella bacteria or the Chinese hamster ovary/HGPRT mammalian cell forward gene mutation assay. Venlafaxine was also not mutagenic or clastogenic in the in vitro BALB/c-3T3 mouse cell transformation assay, the sister chromatid exchange assay in cultured Chinese hamster ovary cells, or in the in vivo chromosomal aberration assay in rat bone marrow. ODV was not clastogenic in the in vitro Chinese hamster ovary cell chromosomal aberration assay or in the in vivo chromosomal aberration assay in rats.

    Impairment of Fertility

    Reproduction and fertility studies of venlafaxine in rats showed no adverse effects of venlafaxine on male or female fertility at oral doses of up to 2 times the maximum recommended human dose of 225 mg/day on a mg/m2 basis. However, when desvenlafaxine succinate, the major human metabolite of venlafaxine, was administered orally to male and female rats, fertility was reduced at the high dose of 300 mg/kg/day, which is 10 (males) and 19 (females) times the AUC exposure at an adult human dose of 100 mg per day.

    There was no effect on fertility at 100 mg/kg/day, which is 3 (males) or 5 (females) times the AUC exposure at an adult human dose of 100 mg per day. These studies did not address reversibility of the effect on fertility. The relevance of these findings to humans is not known.

  • 14 CLINICAL STUDIES

    14.1 Major Depressive Disorder

    The efficacy of Venlafaxine hydrochloride extended-release capsules as a treatment for Major Depressive Disorder (MDD) was established in two placebo-controlled, short-term (8 weeks for study 1; 12 weeks for study 2), flexible-dose studies, with doses starting at 75 mg per day and ranging to 225 mg per day in adult outpatients meeting DSM-III-R or DSM-IV criteria for MDD. In moderately depressed outpatients, the initial dose of venlafaxine was 75 mg per day. In both studies, Venlafaxine hydrochloride extended-release capsules demonstrated superiority over placebo on the primary efficacy measure defined as change from baseline in the HAM-D-21 total score to the endpoint visit, Venlafaxine hydrochloride extended-release capsules also demonstrated superiority over placebo on the key secondary efficacy endpoint, the Clinical Global Impressions (CGI) Severity of Illness scale. Examination of gender subsets of the population studied did not reveal any differential responsiveness on the basis of gender.

    A 4-week study of inpatients meeting DSM-III-R criteria for MDD with melancholia utilizing venlafaxine hydrochloride tablets in a range of 150 to 375 mg per day (divided in a three-times-a-day schedule) demonstrated superiority of venlafaxine hydrochloride tablets over placebo based on the HAM-D-21 total score. The mean dose in completers was 350 mg per day (study 3).

    In a longer-term study, adult outpatients with MDD who had responded during an 8-week open-label study on Venlafaxine hydrochloride extended-release capsules (75, 150, or 225 mg, once daily every morning) were randomized to continuation of their same Venlafaxine hydrochloride extended-release capsules dose or to placebo, for up to 26 weeks of observation for relapse. Response during the open-label phase was defined as a CGI Severity of Illness item score of ≤3 and a HAM-D-21 total score of ≤10 at the day 56 evaluation. Relapse during the double-blind phase was defined as follows: (1) a reappearance of major depressive disorder as defined by DSM-IV criteria and a CGI Severity of Illness item score of ≥4 (moderately ill), (2) 2 consecutive CGI Severity of Illness item scores of ≥4, or (3) a final CGI Severity of Illness item score of ≥4 for any patient who withdrew from the study for any reason. Patients receiving continued Venlafaxine hydrochloride extended-release capsules treatment experienced statistically significantly lower relapse rates over the subsequent 26 weeks compared with those receiving placebo (study 4).

    In a second longer term trial, adult outpatients with MDD, recurrent type, who had responded (HAM-D-21 total score ≤ 12 at the day 56 evaluation) and continued to be improved [defined as the following criteria being met for days 56 through 180: (1) no HAM-D-21 total score ≥20; (2) no more than 2 HAM-D-21 total scores >10, and (3) no single CGI Severity of Illness item score ≥4 (moderately ill)] during an initial 26 weeks of treatment on venlafaxine hydrochloride tablets[100 to 200 mg per day, on a twice daily schedule] were randomized to continuation of their same venlafaxine hydrochloride tablets dose or to placebo. The follow-up period to observe patients for relapse, defined as a CGI Severity of Illness item score ≥4, was for up to 52 weeks. Patients receiving continued venlafaxine hydrochloride tablets treatment experienced statistically significantly lower relapse rates over the subsequent 52 weeks compared with those receiving placebo (study 5).

    14.2 Generalized Anxiety Disorder

    The efficacy of Venlafaxine hydrochloride extended-release capsules as a treatment for Generalized Anxiety Disorder (GAD) was established in two 8-week, placebo-controlled, fixed-dose studies (75 to 225 mg per day), one 6-month, placebo-controlled, flexible-dose study (75 to 225 mg per day), and one 6-month, placebo-controlled, fixed-dose study (37.5, 75, and 150 mg per day) in adult outpatients meeting DSM-IV criteria for GAD.

    In one 8-week study, Venlafaxine hydrochloride extended-release capsules demonstrated superiority over placebo for the 75, 150, and 225 mg per day doses as measured by the Hamilton Rating Scale for Anxiety (HAM-A) total score, both the HAM-A anxiety and tension items, and the Clinical Global Impressions (CGI) scale. However, the 75 and 150 mg per day doses were not as consistently effective as the highest dose (study 1). A second 8-week study evaluating doses of 75 and 150 mg per day and placebo showed that both doses were more effective than placebo on some of these same outcomes; however, the 75 mg per day dose was more consistently effective than the 150 mg per day dose (study 2). A dose-response relationship for effectiveness in GAD was not clearly established in the 75 to 225 mg per day dose range studied.

    Two 6-month studies, one evaluating Venlafaxine hydrochloride extended-release capsules doses of 37.5, 75, and 150 mg per day (study 3) and the other evaluating Venlafaxine hydrochloride extended-release capsules doses of 75 to 225 mg per day (study 4), showed that daily doses of 75 mg or higher were more effective than placebo on the HAM-A total, both the HAM-A anxiety and tension items, and the CGI scale during 6 months of treatment. While there was also evidence for superiority over placebo for the 37.5 mg per day dose, this dose was not as consistently effective as the higher doses.

    Examination of gender subsets of the population studied did not reveal any differential responsiveness on the basis of gender.

    14.3 Social Anxiety Disorder (also known as Social Phobia)

    The efficacy of Venlafaxine hydrochloride extended-release capsules as a treatment for Social Anxiety Disorder (SAD) was established in four double-blind, parallel-group, 12-week, multicenter, placebo-controlled, flexible-dose studies (studies 1-4) and one double-blind, parallel-group, 6-month, placebo-controlled, fixed/flexible-dose study, which included doses in a range of 75 to 225 mg per day in adult outpatients meeting DSM-IV criteria for SAD (study 5).

    In these five studies, Venlafaxine hydrochloride extended-release capsules were statistically significantly more effective than placebo on change from baseline to endpoint on the Liebowitz Social Anxiety Scale (LSAS) total score. There was no evidence for any greater effectiveness of the 150 to 225 mg per day group compared to the 75 mg per day group in the 6-month study.

    Examination of subsets of the population studied did not reveal any differential responsiveness on the basis of gender. There was insufficient information to determine the effect of age or race on outcome in these studies.

    14.4 Panic Disorder

    The efficacy of Venlafaxine hydrochloride extended-release capsules as a treatment for Panic Disorder (PD) was established in two double-blind, 12-week, multicenter, placebo-controlled studies in adult outpatients meeting DSM-IV criteria for PD, with or without agoraphobia. Patients received fixed doses of 75 or 150 mg per day in one study (study 1) and 75 or 225 mg per day in the other study (study 2).

    Efficacy was assessed on the basis of outcomes in three variables: (1) percentage of patients free of full-symptom panic attacks on the Panic and Anticipatory Anxiety Scale (PAAS); (2) mean change from baseline to endpoint on the Panic Disorder Severity Scale (PDSS) total score; and (3) percentage of patients rated as responders (much improved or very much improved) on the Clinical Global Impressions (CGI) Improvement scale. In these two studies, Venlafaxine hydrochloride extended-release capsules were statistically significantly more effective than placebo (for each fixed dose) on all three endpoints, but a dose-response relationship was not clearly established.

    Examination of subsets of the population studied did not reveal any differential responsiveness on the basis of gender. There was insufficient information to determine the effect of age or race on outcome in these studies.

    In a longer term study (study 3), adult outpatients meeting DSM-IV criteria for PD who had responded during a 12-week open phase with Venlafaxine hydrochloride extended-release capsules (75 to 225 mg per day) were randomly assigned to continue the same Venlafaxine hydrochloride extended-release capsules dose (75, 150, or 225 mg) or switch to placebo for observation for relapse under double-blind conditions. Response during the open phase was defined as ≤ 1 full-symptom panic attack per week during the last 2 weeks of the open phase and a CGI Improvement score of 1 (very much improved) or 2 (much improved). Relapse during the double-blind phase was defined as having 2 or more full-symptom panic attacks per week for 2 consecutive weeks or having discontinued due to loss of effectiveness as determined by the investigators during the study. Randomized patients were in response status for a mean time of 34 days prior to being randomized. In the randomized phase following the 12 week open-label period, patients receiving continued Venlafaxine hydrochloride extended-release capsules experienced a statistically significantly longer time to relapse.
