  • BOXED WARNING (What is this?)

    WARNING: SUICIDAL THOUGHTS AND BEHAVIORS

    Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric and young adult patients in short-term studies. Closely monitor all antidepressant-treated patients for clinical worsening, and for emergence of suicidal thoughts and behaviors [see Warnings and Precautions (5.1)]. REMERON/REMERONSolTab is not approved for use in pediatric patients [see Use in Specific Populations (8.4)].

  • 1 INDICATIONS AND USAGE

    REMERON/REMERONSolTab are indicated for the treatment of major depressive disorder (MDD) in adults [see Clinical Studies (14)].

  • 2 DOSAGE AND ADMINISTRATION

    2.1 Recommended Dosage

    The recommended starting dose of REMERON/REMERONSolTab is 15 mg once daily, administered orally, preferably in the evening prior to sleep. If patients do not have an adequate response to the initial 15 mg dose, increase the dose up to a maximum of 45 mg per day. Dose changes should not be made in intervals of less than 1 to 2 weeks to allow sufficient time for evaluation of response to a given dose [see Clinical Pharmacology (12.3)].

    2.2 Administration of REMERONSolTab

    • The tablet should remain in the blister pack until the patient is ready to take it.
    • The patient or caregiver should use dry hands to open the blister.
    • As soon as the blister is opened, the tablet should be removed and placed on the patient's tongue.
    • Use REMERONSolTab immediately after removal from its blister; once removed, it cannot be stored.
    • The whole tablet should be placed on the tongue and allowed to disintegrate without chewing or crushing. Do not attempt to split the tablet.
    • The tablet will disintegrate in saliva so that it can be swallowed.

    2.3 Screen for Bipolar Disorder Prior to Starting REMERON/REMERONSolTab

    Prior to initiating treatment with REMERON/REMERONSolTab or another antidepressant, screen patients for a personal or family history of bipolar disorder, mania, or hypomania [see Warnings and Precautions (5.8)].

    2.4 Switching Patients to or from a Monoamine Oxidase Inhibitor Antidepressant

    At least 14 days must elapse between discontinuation of a monoamine oxidase inhibitor (MAOI) antidepressant and initiation of REMERON/REMERONSolTab. In addition, at least 14 days must elapse after stopping REMERON/REMERONSolTab before starting an MAOI antidepressant [see Contraindications (4) and Warnings and Precautions (5.3)].

    2.5 Dosage Modifications Due to Drug Interactions

    Strong CYP3A Inducers

    An increase in dosage of REMERON/REMERONSolTab may be needed with concomitant strong CYP3A inducer (e.g., carbamazepine, phenytoin, rifampin) use. Conversely, a decrease in dosage of REMERON/REMERONSolTab may be needed if the CYP3A inducer is discontinued [see Drug Interactions (7)].

    Strong CYP3A Inhibitors

    A decrease in dosage of REMERON/REMERONSolTab may be needed with concomitant use of strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin). Conversely, an increase in dosage of REMERON/REMERONSolTab may be needed if the CYP3A4 inhibitor is discontinued [see Drug Interactions (7)].

    Cimetidine

    A decrease in dosage of REMERON/REMERONSolTab may be needed with concomitant use of cimetidine. Conversely, an increase in dosage of REMERON/REMERONSolTab may be needed if cimetidine is discontinued [see Drug Interactions (7)].

    2.6 Discontinuation of REMERON/REMERONSolTab Treatment

    Adverse reactions may occur upon discontinuation or dose reduction of REMERON/REMERONSolTab [see Warnings and Precautions (5.13)]. Gradually reduce the dosage of REMERON/REMERONSolTab rather than stopping abruptly whenever possible.

    • With a known hypersensitivity to mirtazapine or to any of the excipients in REMERON/REMERONSolTab. Severe skin reactions, including Stevens-Johnson syndrome, bullous dermatitis, erythema multiforme and toxic epidermal necrolysis have been reported following the use of REMERON/REMERONSolTab [see Adverse Reactions 6.2].
  • 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 1000 patients treated are provided in Table 1.

    Table 1: Risk Differences of the Number of Patients with Suicidal Thoughts and Behavior in the Pooled Placebo-Controlled Trials of Antidepressants in Pediatric and Adult Patients
    Age RangeDrug-Placebo Difference in Number of Patients with Suicidal Thoughts or Behaviors per 1000 Patients Treated
    Increases Compared to Placebo
    <18 years old14 additional patients
    18–24 years old5 additional patients
    Decreases Compared to Placebo
    25–64 years old1 fewer patient
    ≥65 years old6 fewer patients

    It is unknown whether the 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 of 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 REMERON/REMERONSolTab, in patients whose depression is persistently worse, or who are experiencing emergent suicidal thoughts or behaviors.

    5.2 Agranulocytosis

    In premarketing clinical trials, 2 (1 with Sjögren's Syndrome) out of 2796 patients treated with REMERON developed agranulocytosis [absolute neutrophil count (ANC) <500/mm3 with associated signs and symptoms, e.g., fever, infection, etc.] and a third patient developed severe neutropenia (ANC <500/mm3 without any associated symptoms). For these 3 patients, onset of severe neutropenia was detected on days 61, 9, and 14 of treatment, respectively. All 3 patients recovered after REMERON was stopped. If a patient develops a sore throat, fever, stomatitis, or other signs of infection, along with a low white blood cell (WBC) count, treatment with REMERON/REMERONSolTab should be discontinued and the patient should be closely monitored.

    5.3 Serotonin Syndrome

    Serotonergic antidepressants, including REMERON/REMERONSolTab, 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)]. 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 REMERON/REMERONSolTab with MAOIs is contraindicated. In addition, do not initiate REMERON/REMERONSolTab 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 REMERON/REMERONSolTab, discontinue REMERON/REMERONSolTab before initiating treatment with the MAOI [see Contraindications (4), Drug Interactions (7)].

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

    5.4 Angle-Closure Glaucoma

    The pupillary dilation that occurs following use of many antidepressant drugs, including REMERON/REMERONSolTab, may trigger an angle-closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy.

    5.5 QTc Prolongation and Torsades de Pointes

    The effect of REMERON (mirtazapine) on QTc interval was assessed in a clinical randomized trial with placebo and positive (moxifloxacin) controls involving 54 healthy volunteers using exposure response analysis. This trial showed a positive relationship between mirtazapine concentrations and prolongation of the QTc interval. However, the degree of QT prolongation observed with both 45 mg and 75 mg (1.67 times the maximum recommended daily dose) doses of mirtazapine was not at a level generally considered to be clinically meaningful. During postmarketing use of mirtazapine, cases of QT prolongation, Torsades de Pointes, ventricular tachycardia, and sudden death, have been reported [see Adverse Reactions (6.1, 6.2)]. The majority of reports occurred in association with overdose or in patients with other risk factors for QT prolongation, including concomitant use of QTc-prolonging medicines [see Drug Interactions (7) and Overdosage (10)]. Exercise caution when REMERON/REMERONSolTab is prescribed in patients with known cardiovascular disease or family history of QT prolongation, and in concomitant use with other drugs thought to prolong the QTc interval.

    5.6 Increased Appetite and Weight Gain

    In U.S. controlled clinical studies, appetite increase was reported in 17% of patients treated with REMERON, compared to 2% for placebo. In these same trials, weight gain of ≥7% of body weight was reported in 7.5% of patients treated with mirtazapine, compared to 0% for placebo. In a pool of premarketing U.S. clinical studies, including many patients for long-term, open-label treatment, 8% of patients receiving REMERON discontinued for weight gain.

    In an 8-week-long pediatric clinical trial of doses between 15 to 45 mg/day, 49% of REMERON-treated pediatric patients had a weight gain of at least 7%, compared to 5.7% of placebo-treated patients. The safety and effectiveness of REMERON/REMERONSolTab in pediatric patients with MDD have not been established [see Use in Specific Populations (8.4)].

    5.7 Somnolence

    In U.S. controlled studies, somnolence was reported in 54% of patients treated with REMERON, compared to 18% for placebo. In these studies, somnolence resulted in discontinuation for 10.4% of REMERON-treated patients, compared to 2.2% for placebo. It is unclear whether tolerance develops to the somnolent effects of REMERON/REMERONSolTab. Because of the potentially significant effects of REMERON/REMERONSolTab on impairment of performance, caution patients about engaging in activities that require alertness, including operating hazardous machinery and motor vehicles, until they are reasonably certain that REMERON/REMERONSolTab does not affect them adversely. The concomitant use of benzodiazepines and alcohol with REMERON/REMERONSolTab should be avoided [see Drug Interactions (7)].

    5.8 Activation of Mania or Hypomania

    In patients with bipolar disorder, treating a depressive episode with REMERON/REMERONSolTab or another antidepressant may precipitate a mixed/manic episode. In controlled clinical trials, patients with bipolar disorder were generally excluded; however, symptoms of mania or hypomania were reported in 0.2% of patients treated with REMERON. Prior to initiating treatment with REMERON/REMERONSolTab, screen patients for any personal or family history of bipolar disorder, mania, or hypomania.

    5.9 Seizures

    REMERON/REMERONSolTab has not been systematically evaluated in patients with seizure disorders. In premarketing clinical trials, 1 seizure was reported among the 2796 U.S. and non-U.S. patients treated with REMERON. REMERON/REMERONSolTab should be prescribed with caution in patients with a seizure disorder.

    5.10 Elevated Cholesterol and Triglycerides

    In U.S. controlled studies, nonfasting cholesterol increases to ≥20% above the upper limits of normal were observed in 15% of patients treated with REMERON, compared to 7% for placebo. In these same studies, nonfasting triglyceride increases to ≥500 mg/dL were observed in 6% of patients treated with REMERON, compared to 3% for placebo.

    5.11 Hyponatremia

    Hyponatremia may occur as a result of treatment with serotonergic antidepressants, including REMERON/REMERONSolTab. 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 may lead to falls. Signs and symptoms associated with more severe 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 REMERON/REMERONSolTab and institute appropriate medical intervention. Elderly patients, patients taking diuretics, and those who are volume-depleted may be at greater risk of developing hyponatremia [see Use in Specific Populations (8.5)].

    5.12 Transaminase Elevations

    Clinically significant ALT (SGPT) elevations (≥3 times the upper limit of the normal range) were observed in 2.0% (8/424) of patients treated with REMERON in a pool of short-term, U.S. controlled trials, compared to 0.3% (1/328) of placebo patients. While some patients were discontinued for the ALT increases, in other cases, the enzyme levels returned to normal despite continued REMERON treatment. REMERON/REMERONSolTab should be used with caution in patients with impaired hepatic function [see Use in Specific Populations (8.6), Clinical Pharmacology (12.3)].

    5.13 Discontinuation Syndrome

    There have been reports of adverse reactions upon the discontinuation of REMERON/REMERONSolTab (particularly when abrupt), including but not limited to the following: dizziness, abnormal dreams, sensory disturbances (including paresthesia and electric shock sensations), agitation, anxiety, fatigue, confusion, headache, tremor, nausea, vomiting, and sweating, or other symptoms which may be of clinical significance.

    A gradual reduction in the dosage, rather than an abrupt cessation, is recommended [see Dosage and Administration (2.6)].

    5.14 Use in Patients with Concomitant Illness

    REMERON/REMERONSolTab has not been systematically evaluated or used to any appreciable extent in patients with a recent history of myocardial infarction or other significant heart disease. REMERON was associated with significant orthostatic hypotension in early clinical pharmacology trials with normal volunteers. Orthostatic hypotension was infrequently observed in clinical trials with depressed patients [see Adverse Reactions (6.1)]. REMERON/REMERONSolTab should be used with caution in patients with known cardiovascular or cerebrovascular disease that could be exacerbated by hypotension (history of myocardial infarction, angina, or ischemic stroke) and conditions that would predispose patients to hypotension (dehydration, hypovolemia, and treatment with antihypertensive medication).

    5.15 Risks in Patients with Phenylketonuria

    Phenylalanine can be harmful to patients with phenylketonuria (PKU). REMERONSolTab contains phenylalanine, a component of aspartame. REMERONSolTab contains the following amount of phenylalanine: 2.6 mg in 15 mg orally disintegrating tablet, 5.2 mg in 30 mg orally disintegrating tablet, and 7.8 mg in 45 mg orally disintegrating tablet. Before prescribing REMERONSolTab to a patient with PKU, consider the combined daily amount of phenylalanine from all sources, including REMERONSolTab.

  • 6 ADVERSE REACTIONS

    The following adverse reactions are described in more detail in other sections of the prescribing information:

    6.1 Clinical Trial 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 trials of another drug and may not reflect the rates observed in practice.

    The data described below are from clinical trials in which REMERON/REMERONSolTab was administered to 2796 patients in phase 2 and 3 clinical studies. The trials consisted of double-blind controlled and open-label studies, inpatient and outpatient studies, fixed dose, and titration studies.

    Adverse Reactions Leading to Discontinuation of Treatment

    Approximately 16% of the 453 patients who received REMERON in U.S. 6-week placebo-controlled clinical trials discontinued treatment due to an adverse reaction, compared to 7% of the 361 placebo-treated patients in those studies. The most common reactions leading to discontinuation (≥1% and at a rate at least twice that of placebo) are included in Table 2.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Reproduction studies in pregnant rats and rabbits at doses up to 100 mg/kg and 40 mg/kg, respectively [20 and 17 times the maximum recommended human dose (MRHD) on an mg/m2 basis, respectively], have revealed no evidence of teratogenic effects. However, in rats, there was an increase in post-implantation losses in dams treated with mirtazapine. There was an increase in pup deaths during the first 3 days of lactation and a decrease in pup birth weights. The cause of these deaths is not known. The effects occurred at doses that were 20 times the MRHD, but not at 3 times the MRHD, on an mg/m2 basis. There are no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, REMERON/REMERONSolTab should be used during pregnancy only if clearly needed.

    8.3 Nursing Mothers

    Mirtazapine may be excreted in breast milk. Exercise caution when administering REMERON/REMERONSolTab to nursing women.

    8.4 Pediatric Use

    The safety and effectiveness of REMERON/REMERONSolTab have not been established in pediatric patients with MDD. Two placebo-controlled trials in 258 pediatric patients with MDD have been conducted with REMERON, and the data were insufficient to establish the safety and effectiveness of REMERON/REMERONSolTab in pediatric patients with MDD.

    Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric patients [see Boxed Warning and Warnings and Precautions (5.1)].

    In an 8-week-long clinical trial in pediatric patients receiving doses between 15 to 45 mg per day, 49% of REMERON-treated patients had a weight gain of at least 7%, compared to 5.7% of placebo-treated patients. The mean increase in weight was 4 kg (2 kg SD) for REMERON-treated patients versus 1 kg (2 kg SD) for placebo-treated patients [see Warnings and Precautions (5.6)].

    8.5 Geriatric Use

    Approximately 190 patients ≥65 years of age participated in clinical studies with REMERON. REMERON/REMERONSolTab is known to be substantially excreted by the kidney (75%), and the risk of decreased clearance of this drug is greater in patients with impaired renal function. Pharmacokinetic studies revealed a decreased clearance of mirtazapine in the elderly [see Clinical Pharmacology (12.3)].

    Sedating drugs, including REMERON/REMERONSolTab, may cause confusion and over-sedation in the elderly. Elderly patients may be at greater risk of developing hyponatremia. Caution is indicated when administering REMERON/REMERONSolTab to elderly patients [see Warnings and Precautions (5.11), (5.14) and Clinical Pharmacology (12.3)]. In general, dose selection for an elderly patient should be conservative, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

    8.6 Renal or Hepatic Impairment

    The clearance of mirtazapine is reduced in patients with moderate to severe renal or hepatic impairment. Consequently, plasma mirtazapine levels may be increased in these patient groups, compared to levels observed in patients without renal or hepatic impairment. Dosage decrease may be necessary when administering REMERON/REMERONSolTab to patients with moderate to severe renal or hepatic impairment [see Warnings and Precautions (5.12), Use in Specific Populations (8.5), and Clinical Pharmacology (12.3)].

    8.7 Patients with Phenylketonuria

    REMERONSolTab contains phenylalanine, a component of aspartame. REMERONSolTab contains the following amount of phenylalanine: 2.6 mg in 15 mg orally disintegrating tablet, 5.2 mg in 30 mg orally disintegrating tablet, and 7.8 mg in 45 mg orally disintegrating tablet [see Warnings and Precautions (5.15)].

  • 10 OVERDOSAGE

    Human Experience

    In premarketing clinical studies, there were reports of REMERON overdose alone or in combination with other pharmacological agents. Signs and symptoms reported in association with overdose included disorientation, drowsiness, impaired memory, and tachycardia.

    Based on postmarketing reports, serious outcomes (including fatalities) may occur at dosages higher than the recommended doses, especially with mixed overdoses. In these cases, QT prolongation and Torsades de Pointes have also been reported [see Warnings and Precautions (5.5), Adverse Reactions (6.2), and Drug Interactions (7)].

    Overdose Management

    No specific antidotes for mirtazapine are known.

    Contact Poison Control (1-800-222-1222) for the latest recommendations.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    The mechanism of action of mirtazapine for the treatment of major depressive disorder, is unclear. However, its efficacy could be mediated through its activity as an antagonist at central presynaptic α2-adrenergic inhibitory autoreceptors and heteroreceptors and enhancing central noradrenergic and serotonergic activity.

    12.2 Pharmacodynamics

    In preclinical studies, mirtazapine acts as an antagonist at α2-adrenergic inhibitory autoreceptors and heteroreceptors and as an antagonist at serotonin 5-HT2 and 5-HT3 receptors. Mirtazapine has no significant affinity for the 5-HT1A and 5-HT1B receptors.

    Mirtazapine also acts as an antagonist of histamine (H1) receptors, peripheral α1-adrenergic receptors, and muscarinic receptors. Actions at these receptors may explain some of the other clinical effects of mirtazapine (e.g., its prominent somnolent effects and orthostatic hypotension may be explained by its inhibition of histamine (H1) receptors and peripheral α1-adrenergic receptors, respectively).

    Cardiac Electrophysiology

    The effect of REMERON (mirtazapine) on QTc interval was assessed in healthy subjects. At a dose of 75 mg (1.67 times the maximum recommended dosage), REMERON does not prolong the QTc interval to a clinically meaningful extent.

    12.3 Pharmacokinetics

    Plasma levels of mirtazapine are linearly related to dose over a dose range of 15 to 80 mg (1.78 times the maximum recommended dose). Steady state plasma levels of mirtazapine are attained within 5 days, with about 50% accumulation (accumulation ratio=1.5). The (–) enantiomer has an elimination half-life that is approximately twice as long as the (+) enantiomer and therefore achieves plasma levels that are about 3 times as high as that of the (+) enantiomer.

    Absorption

    Mirtazapine has an absolute bioavailability of about 50% following oral administration. Peak plasma concentrations of mirtazapine are reached within about 2 hours post dose.

    Food Effect

    The presence of food in the stomach has a minimal effect on both the rate and extent of absorption.

    Distribution

    Mirtazapine is approximately 85% bound to plasma proteins over a concentration range of 0.01 to 10 mcg/mL.

    Elimination

    Mirtazapine has a half-life of about 20 to 40 hours following oral administration of REMERON or REMERONSolTab.

    Metabolism

    Mirtazapine is extensively metabolized after oral administration. Major pathways of bio-transformation are demethylation and hydroxylation followed by glucuronide conjugation. In vitro data from human liver microsomes indicate that CYP2D6 and CYP1A2 are involved in the formation of the 8-hydroxy metabolite of mirtazapine, whereas CYP3A is considered to be responsible for the formation of the N-desmethyl and N-oxide metabolite. Several unconjugated metabolites possess pharmacological activity but are present in the plasma at very low levels.

    Excretion

    Mirtazapine and its metabolites are eliminated predominantly (75%) via urine with 15% in feces.

    Specific Populations

    Geriatric Patients

    Following oral administration of REMERON Tablets 20 mg/day for 7 days to subjects of varying ages (range 25 to 74 years old), oral clearance of mirtazapine was reduced in the elderly compared to the younger subjects. The clearance in elderly males was 40% lower compared to younger males, while the clearance was 10% lower in elderly females compared to younger females [see Warnings and Precautions (5.14), Use in Specific Populations (8.5)].

    Male and Female Patients

    The mean elimination half-life of mirtazapine after oral administration ranges from approximately 20 to 40 hours across age and gender subgroups, with females of all ages exhibiting significantly longer elimination half-lives than males (mean half-life of 37 hours for females vs. 26 hours for males).

    Race

    There have been no clinical studies to evaluate the effect of race on the pharmacokinetics of REMERON.

    Patients with Renal Impairment

    When compared to subjects with normal renal function, total body clearance of mirtazapine was reduced approximately 30% in renal impaired patients with GFR=11–39 mL/min/1.73 m2 and approximately 50% in renal impaired patients with GFR=<10 mL/min/1.73 m2) [see Warnings and Precautions (5.14), Use in Specific Populations (8.6)].

    Patients with Hepatic Impairment

    Following a single 15-mg oral dose of REMERON, the oral clearance of mirtazapine in patients with hepatic impairment was decreased by approximately 30%, compared to subjects with normal hepatic function [see Warnings and Precautions (5.12, 5.14), Use in Specific Populations (8.6)].

    Drug Interactions Studies

    Warfarin

    Mirtazapine (30 mg daily) at steady state caused a statistically significant increase (0.2) in the International Normalized Ratio (INR) in subjects treated with warfarin [see Drug Interactions (7)].

    QTc-Prolonging Drugs

    The risk of QT prolongation and/or ventricular arrhythmias (e.g., Torsades de Pointes) may be increased with concomitant use of medicines which prolong the QTc interval (e.g., some antipsychotics and antibiotics) and in mirtazapine overdose [see Warnings and Precautions (5.5), Adverse Reactions (6.1, 6.2), Drug Interactions (7), and Overdosage (10)].

    Phenytoin

    In healthy male subjects (n=18), phenytoin (200 mg daily, at steady state) increased mirtazapine (30 mg daily, at steady state) clearance about 2-fold, resulting in a decrease in average plasma mirtazapine concentrations of 45% [see Drug Interactions (7)]. Mirtazapine did not significantly affect the pharmacokinetics of phenytoin.

    Carbamazepine

    In healthy male subjects (n=24), carbamazepine (400 mg twice a day, at steady state) increased mirtazapine (15 mg twice a day, at steady state) clearance about 2-fold, resulting in a decrease in average plasma mirtazapine concentrations of 60% [see Drug Interactions (7)].

    Cimetidine

    In healthy male subjects (n=12), when cimetidine, a weak inhibitor of CYP1A2, CYP2D6, and CYP3A4, given at 800 mg b.i.d. at steady state was coadministered with mirtazapine (30 mg daily) at steady state, the Area Under the Curve (AUC) of mirtazapine increased more than 50% [see Drug Interactions (7)]. Mirtazapine did not cause relevant changes in the pharmacokinetics of cimetidine.

    Ketoconazole

    In healthy male Caucasian subjects (n=24), coadministration of the strong CYP3A4 inhibitor ketoconazole (200 mg b.i.d. for 6.5 days) increased the peak plasma levels and the AUC of a single 30 mg dose of mirtazapine by approximately 40% and 50%, respectively [see Drug Interactions (7)].

    Amitriptyline

    In healthy, CYP2D6 extensive metabolizer patients (n=32), amitriptyline (75 mg daily), at steady state, did not cause relevant changes to the pharmacokinetics of steady state mirtazapine (30 mg daily); mirtazapine also did not cause relevant changes to the pharmacokinetics of amitriptyline.

    Paroxetine

    In healthy CYP2D6 extensive metabolizer subjects (n=24), mirtazapine (30 mg/day), at steady state, did not cause relevant changes in the pharmacokinetics of steady state paroxetine (40 mg/day), a CYP2D6 inhibitor.

    Lithium

    No relevant clinical effects or significant changes in pharmacokinetics have been observed in healthy male subjects on concurrent treatment with lithium 600 mg/day for 10 days at steady state and a single 30 mg dose of mirtazapine. The effects of higher doses of lithium on the pharmacokinetics of mirtazapine are unknown.

    Risperidone

    Mirtazapine (30 mg daily) at steady state did not influence the pharmacokinetics of risperidone (up to 3 mg twice a day) in subjects (n=6) in need of treatment with an antipsychotic and antidepressant drug.

    Alcohol

    Concomitant administration of alcohol (equivalent to 60 g) had a minimal effect on plasma levels of mirtazapine (15 mg) in 6 healthy male subjects. However, the impairment of cognitive and motor skills produced by REMERON were shown to be additive with those produced by alcohol.

    Diazepam

    Concomitant administration of diazepam (15 mg) had a minimal effect on plasma levels of mirtazapine (15 mg) in 12 healthy subjects. However, the impairment of motor skills produced by REMERON has been shown to be additive with those caused by diazepam.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Carcinogenesis

    Carcinogenicity studies were conducted with mirtazapine given in the diet at doses of 2, 20, and 200 mg/kg/day to mice and 2, 20, and 60 mg/kg/day to rats. The highest doses used are approximately 20 and 12 times the maximum recommended human dose (MRHD) of 45 mg/day, based on body surface area (mg/m2) in mice and rats, respectively. There was an increased incidence of hepatocellular adenoma and carcinoma in male mice at the high dose. In rats, there was an increase in hepatocellular adenoma in females at the mid and high doses and in hepatocellular tumors and thyroid follicular adenoma/cystadenoma and carcinoma in males at the high dose.

    Mutagenesis

    Mirtazapine was not mutagenic or clastogenic and did not induce general DNA damage as determined in several genotoxicity tests: Ames test, in vitro gene mutation assay in Chinese hamster V 79 cells, in vitro sister chromatid exchange assay in cultured rabbit lymphocytes, in vivo bone marrow micronucleus test in rats, and unscheduled DNA synthesis assay in HeLa cells.

    Impairment of Fertility

    In a fertility study in rats, mirtazapine was given at doses up to 100 mg/kg [20 times the maximum recommended human dose (MRHD), based on body surface area (mg/m2)]. Mating and conception were not affected by the drug, but estrous cycling was disrupted at doses that were 3 or more times the MRHD, and pre-implantation losses occurred at 20 times the MRHD.

  • 14 CLINICAL STUDIES

    The efficacy of REMERON as a treatment for major depressive disorder was established in 4 placebo-controlled, 6-week trials in adult outpatients meeting DSM-III criteria for major depressive disorder. Patients were titrated with REMERON from a dose range of 5 mg to 35 mg/day. The mean mirtazapine dose for patients who completed these 4 studies ranged from 21 to 32 mg/day. Overall, these studies demonstrated REMERON to be superior to placebo on at least 3 of the following 4 measures: 21-Item Hamilton Depression Rating Scale (HDRS) total score; HDRS Depressed Mood Item; CGI Severity score; and Montgomery and Asberg Depression Rating Scale (MADRS). Superiority of REMERON over placebo was also found for certain factors of the HDRS, including anxiety/somatization factor and sleep disturbance factor.

    Examination of age and gender subsets of the population did not reveal any differential responsiveness on the basis of these subgroupings.

    In a longer-term study, patients meeting (DSM-IV) criteria for major depressive disorder who had responded during an initial 8 to 12 weeks of acute treatment on REMERON were randomized to continuation of REMERON or placebo for up to 40 weeks of observation for relapse. Response during the open phase was defined as having achieved a HAM-D 17 total score of ≤8 and a CGI-Improvement score of 1 or 2 at 2 consecutive visits beginning with week 6 of the 8 to 12 weeks in the open-label phase of the study. Relapse during the double-blind phase was determined by the individual investigators. Patients receiving continued REMERON treatment experienced significantly lower relapse rates over the subsequent 40 weeks compared to those receiving placebo. This pattern was demonstrated in both male and female patients.

  • 17 PATIENT COUNSELING INFORMATION

    Advise the patient to read the FDA-approved patient labeling (Medication Guide).

    Suicidal Thoughts and Behaviors

    Advise patients and caregivers to look for the emergence of suicidality, especially early during treatment and when the dosage is adjusted up or down, and instruct them to report such symptoms to the healthcare provider [see Boxed Warning and Warnings and Precautions (5.1)].

    Agranulocytosis

    Advise patients to contact their physician if they experience fever, chills, sore throat, mucous membrane ulceration, flu-like complaints, or other symptoms that might suggest infection [see Warnings and Precautions (5.2)].

    Serotonin Syndrome

    Caution patients about the risk of serotonin syndrome, particularly with the concomitant use of REMERON/REMERONSolTab with other serotonergic drugs including triptans, tricyclic antidepressants, fentanyl, lithium, tramadol, tryptophan, buspirone, amphetamines, St. John's Wort, and with drugs that impair metabolism of serotonin (in particular, MAOIs, both those intended to treat psychiatric disorders and also others, such as linezolid). Advise patients to contact their healthcare provider or report to the emergency room if they experience signs or symptoms of serotonin syndrome [see Dosage and Administration (2.4), Contraindications (4), Warnings and Precautions (5.3), Drug Interactions (7)].

    QTc Prolongation and Torsades de Pointes

    Inform patients to consult their physician immediately if they feel faint, lose consciousness, or have heart palpitations [see Warnings and Precautions (5.5), Drug Interactions (7), Overdosage (10)]. Advise patients to inform physicians that they are taking REMERON/REMERONSolTab before any new drug is taken.

    Somnolence

    Advise patients that REMERON/REMERONSolTab may impair judgment, thinking, and particularly, motor skills, because of its prominent sedative effect. Caution patients about performing activities requiring mental alertness, such as operating hazardous machinery or operating a motor vehicle, until they are reasonably certain that REMERON/REMERONSolTab therapy does not adversely affect their ability to engage in such activities. [see Warnings and Precautions (5.7)].

    Alcohol

    Advise patients to avoid alcohol while taking REMERON/REMERONSolTab [see Warnings and Precautions (5.7), Drug Interactions (7)].

    Activation of Mania/Hypomania

    Advise patients and their caregivers to observe for signs of activation of mania/hypomania and instruct them to report such symptoms to the healthcare provider [see Warnings and Precautions (5.8)].

    Discontinuation Syndrome

    Advise patients not to abruptly discontinue REMERON/REMERONSolTab and to discuss any tapering regimen with their healthcare provider. Adverse reactions can occur when REMERON/REMERONSolTab is discontinued [see Dosage and Administration (2.6), Warnings and Precautions (5.13)].

    Allergic Reactions

    Advise patients to notify their healthcare provider if they develop an allergic reaction such as rash, hives, swelling, or difficulty breathing [see Contraindications (4), Adverse Reactions (6.2)].

    Pregnancy

    Advise patients to notify their physician if they become pregnant or intend to become pregnant during REMERON/REMERON SolTab therapy [see Use in Specific Populations (8.1)].

    Nursing

    Advise patients to notify their physician if they are breastfeeding an infant [see Use in Specific Populations (8.3)].

    Angle-Closure Glaucoma

    Patients should be advised that taking REMERON can cause mild pupillary dilation, which in susceptible individuals, can lead to an episode of angle-closure glaucoma. Pre-existing glaucoma is almost always open-angle glaucoma because angle-closure glaucoma, when diagnosed, can be treated definitively with iridectomy. Open-angle glaucoma is not a risk factor for angle-closure glaucoma. Patients may wish to be examined to determine whether they are susceptible to angle-closure, and have a prophylactic procedure (e.g., iridectomy), if they are susceptible [see Warnings and Precautions (5.4).]

    Patients with Phenylketonuria

    Inform patients with phenylketonuria that REMERONSolTab contains phenylalanine [see Warnings and Precautions (5.15)].
