  • BOXED WARNING (What is this?)

    WARNING: SUICIDAL THOUGHTS AND BEHAVIORS

    Antidepressants increased the risk of suicidal thoughts and behaviors in pediatric and youngadult 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)]. Mirtazapine tablets is not approved for use in pediatric patients [see Use in Specific Populations (8.4)].

  • 1 INDICATIONS AND USAGE

    Mirtazapine Tablets 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 for mirtazapine tablets is 15 mg/day, administered in a single dose, 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)].

    2.3 Screen for Bipolar Disorder Prior to Starting Mirtazapine Tablets

    Prior to initiating treatment with mirtazapine tablets 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 mirtazapine tablets. In addition, at least 14 days must elapse after stopping mirtazapine tablets 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 mirtazapine tablets may be needed with concomitant strong CYP3A inducer (e.g., carbamazepine, phenytoin, rifampin) use. Conversely, a decrease in dosage of mirtazapine tablets may be needed if the CYP3A inducer is discontinued [see Drug Interactions (7)].

    Strong CYP3A Inhibitors

    A decrease in dosage of mirtazapine tablets may be needed with concomitant use of strong CYP3A4 inhibitors (e.g., ketoconazole, clarithromycin). Conversely, an increase in dosage of mirtazapine tablets may be needed if the CYP3A inducer is discontinued [see Drug Interactions (7)].

    Cimetidine

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

    2.6 Discontinuation of Mirtazapine Tablets Treatment

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

  • 4 CONTRAINDICATIONS

    Mirtazapine tablets are contraindicated in patients:

    • Taking, or within 14 days of stopping, MAOIs (including the MAOIs linezolid and intravenous methylene blue) because of an increased risk of serotonin syndrome [see Warnings and Precautions (5.3), Drug Interactions (7)], Drug Interactions (7)].

    • With a known hypersensitivity to mirtazapine or to any of the excipients in mirtazapine tablets. Severe skin reactions, including Stevens-Johnson syndrome, bullous dermatitis, erythema multiforme and toxic epidermal necrolysis have been reported following the use of mirtazapine tablets [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
    Age RangeDrug-placebo Difference in Number of Cases of Suicidality per 1,000 Patients Treated
    Increases Compared to Placebo
    <1814 additional cases
    18 to 245 additional cases
    Decreases Compared to Placebo
    25 to 641 fewer case
    ≥656 fewer cases

    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 mirtazapine tablets, 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 mirtazapine tablets 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 mirtazapine tablets were 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 mirtazapine tablets should be discontinued and the patient should be closely monitored.

    5.3 Serotonin Syndrome

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

    Monitor all patients taking mirtazapine tablets for the emergence of serotonin syndrome. Discontinue treatment with mirtazapine tablets and any concomitant serotonergic agents immediately if the above symptoms occur and initiate supportive symptomatic treatment. If concomitant use of mirtazapine tablets with other serotonergic drugs is clinically warranted, inform patients of the increased risk for serotonin syndrome and monitor for symptoms., 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 mirtazapine tablets, may trigger an angle-closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy.

    5.5 QT Prolongation and Torsades de Pointes

    The effect of mirtazapine tablets 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 mirtazapine tablets 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 mirtazapine tablets, 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 mirtazapine tablets discontinued for weight gain.

    In an 8-week-long pediatric clinical trial of doses between 15 to 45 mg/day, 49% of mirtazapine tablets-treated pediatric patients had a weight gain of at least 7%, compared to 5.7% of placebo-treated patients. The safety and effectiveness of mirtazapine tablets 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 mirtazapine tablets, compared to 18% for placebo. In these studies, somnolence resulted in discontinuation for 10.4% of mirtazapine tablets-treated patients, compared to 2.2% for placebo. It is unclear whether tolerance develops to the somnolent effects of mirtazapine tablets. Because of the potentially significant effects of mirtazapine tablets 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 mirtazapine does not affect them adversely. The concomitant use of benzodiazepines and alcohol with mirtazapine tablets should be avoided [see Drug Interactions (7)].

    5.8 Activation of Mania or Hypomania

    In patients with bipolar disorder, treating a depressive episode with mirtazapine tablets 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 mirtazapine tablets. Prior to initiating treatment with mirtazapine tablets, screen patients for any personal or family history of bipolar disorder, mania, or hypomania.

    5.9 Seizures

    Mirtazapine tablets 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 mirtazapine tablets. Mirtazapine tablets 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 mirtazapine tablets, compared to 7% for placebo. In these same studies, nonfasting triglyceride increases to ≥500 mg/dL were observed in 6% of patients treated with mirtazapine tablets, compared to 3% for placebo.

    5.11 Hyponatremia

    Hyponatremia may occur as a result of treatment with serotonergic antidepressants, includingmirtazapine tablets. Cases with serum sodium lower than 110 mmol/L have been reported.mirtazapine tablets. 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 mirtazapine tablets 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 mirtazapine tablets 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 mirtazapine treatment.Mirtazapine tablets 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 mirtazapine tablets (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

    Mirtazapine tablets have not been systematically evaluated or used to any appreciable extentin patients with a recent history of myocardial infarction or other significant heart disease. Mirtazapine tablets were 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)]. Mirtazapine tablets 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).

    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 mirtazapine tablets were 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 mirtazapine tablets in US 6-week controlled clinical trials discontinued treatment due to an adverse experience, compared to 7% of the 361 placebo-treated patients in those studies. The most common events (≥1%) associated with discontinuation and considered to be drug related (i.e., those events associated with dropout at a rate at least twice that of placebo) are included in Table 2.

  • 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 during pregnancy. Healthcare providers are encouraged to register patients by calling theNational Pregnancy Registry for Antidepressants at 1-844-405-6185 or visiting online at https://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/antidepressants/.

    Risk Summary

    Prolonged experience with mirtazapine in pregnant women, based on published observational studiesand postmarketing reports, has not reliably identified a drug-associated risk of major birth defects,miscarriage or adverse maternal or fetal outcomes. There are risks associated with untreated depressionin pregnancy (see Clinical Considerations).

    In animal reproduction studies, oral administration of mirtazapine to pregnant rats and rabbits during theperiod of organogenesis revealed no evidence of teratogenic effects up to 20 and 17 times the maximum recommended human dose (MRHD) of 45 mg, respectively, based on mg/m2 body surface area.However, in rats, there was an increase in post implantation loss at 20 times the MRHD based on mg/m2body surface area. Oral administration of mirtazapine to pregnant rats during pregnancy and lactation resulted in an increase in pup deaths and a decrease in pup birth weights at doses 20 times the MRHDbased on mg/m2 body surface area (see Data).

    The estimated background risk of major birth defects and miscarriage for the indicated population 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 ofmajor depression than women who continue antidepressants. This finding is from a prospective,longitudinal study that followed 201 pregnant women with a history of major depressive disorder whowere euthymic and taking antidepressants at the beginning of pregnancy. Consider the risk of untreateddepression when discontinuing or changing treatment with antidepressant medication during pregnancyand postpartum.

    Data

    Animal Data

    Mirtazapine was administered orally to pregnant rats and rabbits during the period of organogenesis atdoses of 2.5, 15, and 100 mg/kg/day and 2.5, 10, and 40 mg/kg/day, respectively, which are up to 20 and17 times the maximum recommended human dose (MRHD) of 45 mg based on mg/m2 body surface area,respectively. No evidence of teratogenic effects was observed. However, in rats, there was an increase inpost implantation loss in dams treated with mirtazapine at 100 mg/kg/day which is 20 times the MRHDbased on mg/m2 body surface area. Oral administration of mirtazapine at doses of 2.5, 15, and 100mg/kg/day to pregnant rats during pregnancy and lactation resulted in an increase in pup deaths duringthe first 3 days of lactation and a decrease in pup birth weights at 20 times the MRHD based on mg/m2body surface area. The cause of these deaths is not known. The no effect dose level is 3 times theMRHD based on mg/m2 body surface area.

    8.2 Lactation

    Risk Summary

    Data from published literature report the presence of mirtazapine in human milk at low levels with relativeinfant doses for mirtazapine ranging between 0.6 and 2.8% of the maternal weight-adjusted dose (seeData). No adverse effects on the breastfed infant have been reported in most cases of maternal use ofData). No adverse effects on the breastfed infant have been reported in most cases of maternal use ofmirtazapine. There are no data on the effects of mirtazapine on milk production.

    The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for mirtazapine and any potential adverse effects on the breastfed infant from mirtazapine or from the underlying maternal condition.

    Data

    In a published pooled analysis of 8 breastfeeding mother-infant pairs, the mean (min, max) total relativeinfant doses for mirtazapine and its desmethyl metabolite were 1.5% (0.6%, 2.8%) and 0.4% (0.1%,0.7%) of the maternal weight-adjusted dose (median (min, max) dose of 38 mg (30 mg, 120 mg),respectively). No adverse drug effects were reported for any of the infants.

    8.4 Pediatric Use

    The safety and effectiveness of mirtazapine tablets have not been established in pediatric patients with MDD. Two placebo-controlled trials in 258 pediatric patients with MDD have been conducted with mirtazapine tablets, and the data were insufficient to establish the safety and effectiveness of mirtazapine tablets 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 mirtazapine tablets-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 mirtazapine tablets-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 mirtazapine tablets. Mirtazapine tablets are 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 mirtazapine tablets, may cause confusion and over-sedation in the elderly. Elderly patients may be at greater risk of developing hyponatremia. Caution is indicated when administering mirtazapine tablets 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 mirtazapine tablets 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)].

  • 10 OVERDOSAGE

    Human Experience

    In premarketing clinical studies, there were reports of mirtazapine tablets 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 andTorsades 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.

  • 11 DESCRIPTION

    Mirtazapine tablets contain mirtazapine. Mirtazapine has a tetracyclic chemical structure and belongs to the piperazino-azepine group of compounds. It is designated 1,2,3,4,10,14b-hexahydro-2­ methylpyrazino [2,1-a] pyrido [2,3-c][2] benzazepine and has the empirical formula of C17H19N3. Its molecular weight is 265.35. The structural formula is the following and it is the racemic mixture:

    structure

    Mirtazapine is a white to creamy white crystalline powder which is practically insoluble in water.

    Mirtazapine tablets are available for oral administration as scored film-coated tablets containing 15 or 30 mg of mirtazapine. Each tablet contains the following inactive ingredients: colloidal silicon dioxide anhydrous, corn starch, ferric oxide (yellow), hydroxypropyl cellulose, hypromellose, magnesium stearate, lactose monohydrate, polyethylene glycol 8000, and titanium dioxide. The 30 mg tablets also contain ferric oxide (red).

  • 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 auto-receptors and heteroreceptors and enhancing central noradrenergic and serotonergic activity.

    12.2 Pharmacodynamics

    In preclinical studies, mirtazapine acts as an antagonist at α2-adrenergic inhibitory auto-receptors 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 mirtazapine tablets on QTc interval was assessed in healthy subjects. At a dose of 75 mg (1.67 times the maximum recommended dosage), mirtazapine tablets do 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.

    Absorbtion

    Mirtazapine has an absolute bioavailability of about 50% following oral administration. Peak plasma concentrations of mirtazapine are reached within about 2 hours post dose.0% 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 to10 mcg/mL.

    Elimination

    Mirtazapine has a half-life of about 20 to 40 hours following oral administration of mirtazapine tablets -life of about 20 to 40 hours following oral administration of mirtazapine tablets

    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 presentin 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 mirtazapine 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 mirtazapine tablets.

    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 mirtazapine tablets, 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 theInternational 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 single30 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 to3 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 mirtazapine tablets 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 mirtazapine tablets 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, and200 mg/kg/day to mice and 2, 20, and 60 mg/kg/day to rats. The highest doses used are approximately20 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 mirtazapine tablets 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 mirtazapine tablets 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 mirtazapine tablets 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 mirtazapine tablets 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 mirtazapine tablets were randomized to continuation of mirtazapine tablets 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 mirtazapine tablets 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.

    Angle-Closure Glaucoma

    Patients should be advised that taking mirtazapine 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).]
