  • 1 INDICATIONS AND USAGE

    Trazodone hydrochloride tablets are indicated for the treatment of major depressive disorder (MDD) in adults.

    Close
  • 2 DOSAGE AND ADMINISTRATION

    2.1 Dose Selection

    An initial dose of 150 mg/day in divided doses is suggested. The dosage should be initiated at a low-dose and increased gradually, noting the clinical response and any evidence of intolerance. Occurrence of drowsiness may require the administration of a major portion of the daily dose at bedtime or a reduction of dosage.

    The dose may be increased by 50 mg/day every 3 to 4 days. The maximum dose for outpatients usually should not exceed 400 mg/day in divided doses. Inpatients (i.e., more severely depressed patients) may be given up to but not in excess of 600 mg/day in divided doses.

    Once an adequate response has been achieved, dosage may be gradually reduced, with subsequent adjustment depending on therapeutic response.

    2.2 Improtant Administration Instructions

    Trazodone hydrochloride tablets can be swallowed whole or administered as a half tablet by breaking the tablet along the score line.

    Trazodone hydrochloride tablets should be taken shortly after a meal or light snack.

    2.3 Screen for Bipolar Disorder Prior to Starting Trazodone

    Prior to initiating treatment with trazodone hydrochloride tablets or another antidepressant, screen patients for a personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions (5.7)].

    2.4 Switchning to or from Monoamine Oxidase Inhibitor Antidepressant

    At least 14 days must elapse between discontinuation of a monoamine oxidase inhibitor (MAOI) antidepressant and initiation of trazodone hydrochloride tablets. In addition, at

    least 14 days must elapse after stopping trazodone hydrochloride tablets before starting an MAOI antidepressant [see Contraindications (4), Warnings and Precautions (5.2)].

    2.5 Dosage Recommendations for Concomitant Use with Strong CYP3A4 Inhibitors or Inducers

    Coadministration with Strong CYP3A4 Inhibitors

    Consider reducing trazodone dose based on tolerability when trazodone is coadministered with a strong CYP3A4 inhibitor [see Drug Interactions (7.1)].

    Coadministration with Strong CYP3A4 Inducers

    Consider increasing trazodone dose based on therapeutic response when trazodone is coadministered with a strong CYP3A4 inducer [see Drug Interactions (7.1)].

    2.6 Discontinuation of Treatment with Trazodone

    Adverse reactions may occur upon discontinuation of trazodone [See Warnings and Precautions (5.8)]. Gradually reduce the dosage rather than stopping trazodone abruptly whenever possible.

  • 4 CONTRAINDICATIONS

    Trazodone hydrochloride tablets are contraindicated in:

    •   Patients taking, or within 14 days of stopping, monoamine oxidase inhibitors (MAOIs), including MAOIs such as linezolid or intravenous methylene blue, because of an increased risk of serotonin syndrome [see Warnings and Precautions (5.2), Drug Interactions (7.1)].
    Close
  • 5 WARNINGS AND PRECAUTIONS

    5.1 Suicidal Thoughts and Behaviors in Pediatric and Young Adult Patients

    In pooled analyses of placebo-controlled trials of antidepressant drugs (SSRIs and other antidepressant classes) that included approximately 77,000 adult patients and over 4,400 pediatric patients, the incidence of suicidal thoughts and behaviors in pediatric and young adult patients was greater in antidepressant-treated patients than in placebo-treated patients. The drug-placebo differences in the number of cases of suicidal thoughts and behaviors per 1,000 patients treated are provided in Table 1.

    No suicides occurred in any of the pediatric studies. There were suicides in the adult studies, but the number was not sufficient to reach any conclusion about antidepressant drug effect on suicide.

    It is unknown whether the risk of suicidal thoughts and behaviors in pediatric and young adult patients 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.

    Monitor all antidepressant-treated patients 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 trazodone, 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) and SSRIs, including trazodone, 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, 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, and 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 trazodone with MAOIs is contraindicated. In addition, do not initiate trazodone 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 trazodone, discontinue trazodone before initiating treatment with the MAOI [see Contraindications (4), Drug Interactions (7.1)].

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

    5.3 Cardiac Arrhythmias

    Clinical studies indicate that trazodone hydrochloride may be arrhythmogenic in patients with preexisting cardiac disease. Arrhythmias identified include isolated PVCs, ventricular couplets, tachycardia with syncope, and torsade de pointes. Postmarketing events, including torsade de pointes have been reported at doses of 100 mg or less with the immediate-release form of trazodone. Trazodone should also be avoided in patients with a history of cardiac arrhythmias, as well as other circumstances that may increase the risk of the occurrence of torsade de pointes and/or sudden death, including symptomatic bradycardia, hypokalemia or hypomagnesemia, and the presence of congenital prolongation of the QT interval. Trazodone is not recommended for use during the initial recovery phase of myocardial infarction. Caution should be used when administering trazodone to patients with cardiac disease and such patients should be closely monitored, since antidepressant drugs (including trazodone) may cause cardiac arrhythmias [see Adverse Reactions (6.2)].

    Trazodone prolongs the QT/QTc interval. The use of trazodone should be avoided in patients with known QT prolongation or in combination with other drugs that are inhibitors of CYP3A4 (e.g., itraconazole, clarithromycin, voriconazole), or known to prolong QT interval including Class 1A antiarrhythmics (e.g., quinidine, procainamide) or Class 3 antiarrhythmics (e.g., amiodarone, sotalol), certain antipsychotic medications (e.g., ziprasidone, chlorpromazine, thioridazine), and certain antibiotics (e.g., gatifloxacin). Concomitant administration of drugs may increase the risk of cardiac arrhythmia [see Drug Interactions (7.1)].

    5.4 Orthostatic Hypotension and Syncope

    Hypotension, including orthostatic hypotension and syncope has been reported in patients receiving trazodone hydrochloride. Concomitant use with an antihypertensive may require a reduction in the dose of the antihypertensive drug.

    5.5 Increased Risk of Bleeding

    Drugs that interfere with serotonin reuptake inhibition, including trazodone, increase the risk of bleeding events. Concomitant use of aspirin, nonsteroidal anti-inflammatory drugs (NSAIDS), other antiplatelet drugs, warfarin, and other anticoagulants 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. Bleeding events related to drugs that interfere with serotonin reuptake have ranged from ecchymosis, hematoma, epistaxis, and petechiae to life-threatening hemorrhages.

    Inform patients about the risk of bleeding associated with the concomitant use of trazodone and antiplatelet agents or anticoagulants. For patients taking warfarin, carefully monitor coagulation indices when initiating, titrating, or discontinuing trazodone.

    5.6 Priapism

    Cases of priapism (painful erections greater than 6 hours in duration) have been reported in men receiving trazodone. Priapism, if not treated promptly, can result in irreversible damage to the erectile tissue. Men who have an erection lasting greater than 4 hours, whether painful or not, should immediately discontinue the drug and seek emergency medical attention [see Adverse Reactions (6.2), Overdosage (10)].

    Trazodone should be used with caution in men who have conditions that might predispose them to priapism (e.g., sickle cell anemia, multiple myeloma, or leukemia), or in men with anatomical deformation of the penis (e.g., angulation, cavernosal fibrosis, or Peyronie's disease).

    5.7 Activation of Mania or Hypomania

    In patients with bipolar disorder, treating a depressive episode with trazodone or another antidepressant may precipitate a mixed/manic episode. Activation of mania/hypomania has been reported in a small proportion of patients with major affective disorder who were treated with antidepressants. Prior to initiating treatment with trazodone, screen patients for any personal or family history of bipolar disorder, mania, or hypomania [see Dosage and Administration (2.3)].

    5.8 Discontinuation Syndrome

    Adverse reactions after discontinuation of serotonergic antidepressants, particularly after abrupt discontinuation, include: nausea, sweating, dysphoric mood, irritability, agitation, dizziness, sensory disturbances (e.g., paresthesia, such as electric shock sensations), tremor, anxiety, confusion, headache, lethargy, emotional lability, insomnia, hypomania, tinnitus, and seizures. A gradual reduction in dosage rather than abrupt cessation is recommended whenever possible [See Dosage and Administration (2.6)].

    5.9 Potential for Cognitive and Motor Impairment

    Trazodone may cause somnolence or sedation and may impair the mental and/or physical ability required for the performance of potentially hazardous tasks. Patients should be cautioned about operating hazardous machinery, including automobiles, until they are reasonably certain that the drug treatment does not affect them adversely.

    5.10 Angle-Closure Glaucoma

    The pupillary dilation that occurs following use of many antidepressant drugs including trazodone 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 trazodone, in patients with untreated anatomically narrow angles.

    5.11 Hyponatremia

    Hyponatremia may occur as a result of treatment with SNRIs and SSRIs, including trazodone. Cases with serum sodium lower than 110 mmol/L have been reported. Signs and symptoms of hyponatremia include headache, difficulty concentrating, memory impairment, confusion, weakness, and unsteadiness, which can lead to falls. Signs and symptoms associated with more severe and/or acute cases have included hallucination, syncope, seizure, coma, respiratory arrest, and death. In many cases, this hyponatremia appears to be the result of the syndrome of inappropriate antidiuretic hormone secretion (SIADH).

    In patients with symptomatic hyponatremia, discontinue trazodone and institute appropriate medical intervention. Elderly patients, patients taking diuretics, and those who are volume-depleted may be at greater risk of developing hyponatremia with SSRIs and SNRIs [see Use in Specific Populations (8.5)].

    Other adverse reactions occurring at an incidence of <2% with the use of trazodone hydrochloride in the controlled clinical studies: akathisia, allergic reaction, anemia, chest pain, delayed urine flow, early menses, flatulence, hallucinations/delusions, hematuria, hypersalivation, hypomania, impaired memory, impaired speech, impotence, increased appetite, increased libido, increased urinary frequency, missed periods, muscle twitches, numbness, paresthesia, retrograde ejaculation, shortness of breath, and tachycardia/palpitations. Occasional sinus bradycardia has occurred in long-term studies.

    6.2 Postmarketing Experience

    The following adverse reactions have been identified during post-approval use of trazodone. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to estimate their frequency or establish a causal relationship to drug exposure:

    Cardiac disorders: cardiospasm, congestive heart failure, conduction block, orthostatic hypotension and syncope, palpitations, bradycardia, atrial fibrillation, myocardial infarction, cardiac arrest, arrhythmia, ventricular ectopic activity, including ventricular tachycardia and QT prolongation. Prolonged QT interval, torsade de pointes, and ventricular tachycardia have been reported at doses of 100 mg per day or less [see Warnings and Precautions (5.3)].

    Endocrine disorders: inappropriate ADH syndrome

    Eye disorders: diplopia

    Gastrointestinal disorders: increased salivation, nausea/vomiting

  • 7 DRUG INTERACTIONS

    MAOIs

    MAOIs should not be used within 14 days of trazodone [see Warnings and Precautions ( 5.8)].

    Central Nervous System (CNS) Depressants

    Trazodone may enhance the response to alcohol, barbiturates, and other CNS depressants.

    Cytochrome P450 3A4 Inhibitors

    In vitro drug metabolism studies suggest that there is a potential for drug interactions when trazodone is given with cytochrome P450 3A4 (CYP3A4) inhibitors. The effect of short-term administration of ritonavir (200 mg twice daily, 4 doses) on the pharmacokinetics of a single dose of trazodone (50 mg) has been studied in 10 healthy subjects. The C max of trazodone increased by 34%, the AUC increased 2.4 fold, the half-life increased by 2.2 fold, and the clearance decreased by 52%. Adverse effects including nausea, hypotension, and syncope were observed when ritonavir and trazodone were coadministered. It is likely that ketoconazole, indinavir, and other CYP3A4 inhibitors such as itraconazole may lead to substantial increases in trazodone plasma concentrations with the potential for adverse effects. If trazodone is used with a potent CYP3A4 inhibitor, the risk of cardiac arrhythmia may be increased [see Warnings and Precautions ( 5.4)] and a lower dose of trazodone should be considered.

    Cytochrome P450 Inducers (e.g., Carbamazepine)

    Carbamazepine induces CYP3A4. Following coadministration of carbamazepine 400 mg per day with trazodone 100 mg to 300 mg daily, carbamazepine reduced plasma concentrations of trazodone and m-chlorophenlypiperazine (an active metabolite) by 76% and 60% respectively, compared to pre-carbamazepine values. Patients should be closely monitored to see if there is a need for an increased dose of trazodone when taking both drugs.

    Digoxin and Phenytoin

    Increased serum digoxin or phenytoin levels have been reported in patients receiving trazodone concurrently with either of these drugs. Monitor serum levels and adjust dosages as needed.

    Serotonergic Drugs

    Based on the mechanism of action of trazodone and the potential for serotonin syndrome, caution is advised when trazodone is coadministered with other drugs that may affect the neurotransmitter systems [ see Warnings and Precautions ( 5.2) ].

    NSAIDs, Aspirin, or Other Drugs Affecting Coagulation or Bleeding

    Due to a possible association between serotonin modulating drugs and gastrointestinal bleeding, patients should be monitored for and cautioned about the potential risk of bleeding associated with the concomitant use of trazodone and NSAIDs, aspirin, or other drugs that affect coagulation or bleeding [s ee Warnings and Precautions ( 5.7) ].

    Warfarin

    There have been reports of altered (either increased or decreased) prothrombin times in taking both warfarin and trazodone.

    7.1 Drugs Having Clinically Important Interactions with Trazodone

    Table 3 Clinically Important Drug Interactions with Trazodone
    Monoamine Oxidase Inhibitors (MAOIs)
    Clinical Impact:
    The concomitant use of MAOIs and serotonergic drugs including trazodone increases the risk of serotonin syndrome.
    Intervention:

    Trazodone is contraindicated in patients taking MAOIs, including MAOIs such as linezolid or intravenous methylene blue [see Contraindications (4), Dosage and Administration (2.3, 2.4), and Warnings and Precautions (5.2)].
    Examples:
    isocarboxazid, moclobemide, phenelzine, selegiline, tranylcypromine
    Other Serotonergic Drugs
    Clinical Impact:

    The concomitant use of serotonergic drugs including trazodone and other serotonergic drugs increases the risk of serotonin syndrome.
    Intervention:

    Monitor patients for signs and symptoms of serotonin syndrome, particularly during trazodone initiation. If serotonin syndrome occurs, consider discontinuation of trazodone and/or concomitant serotonergic drugs [see Warnings and Precautions (5.2)].
    Examples:

    triptans, antidepressants (tricyclic and serotonin uptake inhibitors), fentanyl, lithium, tramadol, tryptophan, buspirone, and St. John's Wort
    Antiplatelet Agents and Anticoagulants
    Clinical Impact:

    Serotonin release by platelets plays an important role in hemostasis. The concurrent use of an antiplatelet agent or anticoagulant with trazodone may potentiate the risk of bleeding.
    Intervention:

    Inform patients of the increased risk of bleeding with the concomitant use of trazodone and antiplatelet agents and anticoagulants. For patients taking warfarin, carefully monitor the international normalized ratio (INR) when initiating or discontinuing trazodone [see Warnings and Precautions (5.5)].
    Examples:
    warfarin, rivaroxaban, dabigatran, clopidogrel
    Strong CYP3A4 Inhibitors
    Clinical Impact:
    The concomitant use of trazodone and strong CYP3A4 inhibitors increased the exposure of trazodone compared to the use of trazodone alone .
    Intervention:

    If trazodone is used with a potent CYP3A4 inhibitor, the risk of adverse reactions, including cardiac arrhythmias, may be increased and a lower dose of trazodone should be considered [see Dosage and Administration (2.5), Warnings and Precautions (5.3)].
    Examples:
    itraconazole, ketoconazole, clarithromycin, indinavir
    Strong CYP3A4 Inducers
    Clinical Impact:

    The concomitant use of trazodone and strong CYP3A4 inducers decreased the exposure of trazodone compared to the use of trazodone alone .
    Intervention:

    Patients should be closely monitored to see if there is a need for an increased dose of trazodone when taking CYP3A4 inducers [see Dosage and Administration (2.5)].
    Examples:
    rifampin, carbamazepine, phenytoin, St. John's wort
    Digoxin and Phenytoin
    Clinical Impact:

    Digoxin and phenytoin are narrow therapeutic index drugs. Concomitant use of trazodone can increase digoxin or phenytoin concentrations.
    Intervention:

    Measure serum digoxin or phenytoin concentrations before initiating concomitant use of trazodone. Continue monitoring and reduce digoxin or phenytoin dose as necessary.
    Examples:
    digoxin, phenytoin
    Central Nervous System (CNS) Depressants
    Clinical Impact:
    Trazodone may enhance the response CNS depressants.
    Intervention:

    Patients should be counseled that trazodone may enhance the response to alcohol, barbiturates, and other CNS depressants.
    Examples:
    alcohol, barbiturates
    QT Interval Prolongation
    Clinical Impact:

    Concomitant use of drugs that prolong the QT interval may add to the QT effects of trazodone and increase the risk of cardiac arrhythmia.
    Intervention:

    Avoid the use of trazodone in combination with other drugs known to prolong QTc [see Warnings and Precautions (5.3)] .
    Examples:

    Class 1A antiarrhythmics: quinidine, procainamide, disopyramide; Class 3 antiarrhythmics: amiodarone, sotalol;
    Antipsychotics: ziprasidone, chlorpromazine, thioridazine; Antibiotics: gatifloxacin

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Teratogenic Effects

    Pregnancy Category C

    Trazodone hydrochloride has been shown to cause increased fetal resorption and other adverse effects on the fetus in the rat when given at dose levels approximately 6 to 9 times the maximum recommended human dose (MRHD) of 400 mg/day on mg/m 2in adolescents. There is also an increase in congenital anomalies in the rabbit at approximately 6 to 17 times the MRHD  on mg/m 2 basis in adolescents. There are no adequate and well-controlled studies in pregnant women. Trazodone hydrochloride should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

    Animal Data

    No teratogenic effects were observed when trazodone was given to pregnant rats and rabbits during the period of organogenesis at oral doses up to 450 mg/kg/day. This dose is 9 and 17 times, in rats and rabbits, respectively, the maximum recommended human dose (MRHD) of 400 mg/day on mg/m 2 basis in adolescents. Increased fetal resorption and other adverse effects on the fetus in rats at 6 to 9 times the MRHD and increase in congenital anomalies in rabbits at 6 to 17 times the MRHD on mg/m 2 basis in adolescents were observed.

    8.3 Nursing Mothers

    Trazodone and/or its metabolites have been found in the milk of lactating rats, suggesting that the drug may be secreted in human milk. Caution should be exercised when trazodone is administered to a nursing woman.

    8.4 Pediatric Use

    Safety and effectiveness in the pediatric population have not been established.  Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric patients [ see Boxed Warning, Warnings and Precautions ( 5.1) ].

    8.5 Geriatric Use

    Reported clinical literature and experience with trazodone has not identified differences in responses between elderly and younger patients. However, as experience in the elderly with trazodone hydrochloride is limited, it should be used with caution in geriatric patients.

    Serotonergic antidepressants have been associated with cases of clinically significant hyponatremia in elderly patients who may be at greater risk for this adverse reaction [ see Warnings and Precautions (5.11)].

    8.6 Renal Impairment

    Trazodone has not been studied in patients with renal impairment. Trazodone should be used with caution in this population.

    8.7 Hepatic Impairment

    Trazodone has not been studied in patients with hepatic impairment. Trazodone should be used with caution in this population.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    The mechanism of trazodone's antidepressant action is not fully understood, but is thought to be related to its enhancement of serotonergic activity in the CNS. Trazodone is both a selective serotonin reuptake inhibitor (SSRI) and a 5HT2 receptor antagonist and the net result of this action on serotonergic transmission and its role in trazodone's antidepressant effect is unknown.

    12.2 Pharmacodynamics

    Preclinical studies have shown that trazodone selectively inhibits neuronal reuptake of serotonin (Ki = 367 nM) and acts as an antagonist at 5-HT-2A (Ki = 35.6 nM) serotonin receptors. Trazodone is also an antagonist at several other monoaminergic receptors including 5-HT2B (Ki = 78.4 nM), 5-HT2C (Ki = 224 nM), α1A (Ki = 153 nM), α2C (Ki = 155 nM) receptors and it is a partial agonist at 5HT1A (Ki = 118 nM) receptor.

    Trazodone antagonizes alpha 1-adrenergic receptors, a property which may be associated with postural hypotension.

    12.3 Pharmacokinetics

    Absorption

    In humans, trazodone hydrochloride is absorbed after oral administration without selective localization in any tissue. When trazodone hydrochloride is taken shortly after ingestion of food, there may be an increase in the amount of drug absorbed, a decrease in maximum concentration and a lengthening in the time to maximum concentration. Peak plasma levels occur approximately one hour after dosing when trazodone hydrochloride is taken on an empty stomach or 2 hours after dosing when taken with food.

    Metabolism

    In vitro studies in human liver microsomes show that trazodone is metabolized, via oxidative cleavage, to an active metabolite, m-chlorophenylpiperazine (mCPP) by CYP3A4. Other metabolic pathways that may be involved in the metabolism of trazodone have not been well characterized. Trazodone is extensively metabolized; less than 1% of an oral dose is excreted unchanged in the urine.

    Elimination

    In some patients trazodone may accumulate in the plasma.

    Protein Binding

    Trazodone is 89 to 95% protein bound in vitro at concentrations attained with therapeutic doses in humans.

  • 13 NONCLINICAL TOXICOLOGY

    Carcinogenesis

    No drug- or dose-related occurrence of carcinogenesis was evident in rats receiving trazodone in daily oral doses up to7.3 times the maximum recommended human dose (MRSD) of 400 mg/day on mg/m 2 basis.

    Mutagenesis

    No genotoxicity studies were conducted with trazodone.
