Mirtazapine Tablets are indicated for the treatment of major depressive disorder.

The efficacy of Mirtazapine in the treatment of major depressive disorder was established in 6-week controlled trials of outpatients whose diagnoses corresponded most closely to the Diagnostic and Statistical Manual of Mental Disorders- 3rd edition (DSM-III) category of major depressive disorder

A major depressive episode (DSM-IV) implies a prominent and relatively persistent (nearly every day for at least 2 weeks) depressed or dysphoric mood that usually interferes with daily functioning, and includes at least 5 of the following 9 symptoms: depressed mood, loss of interest in usual activities, significant change in weight and/or appetite, insomnia or hypersomnia, psychomotor agitation or retardation, increased fatigue, feelings of guilt or worthlessness, slowed thinking or impaired concentration, a suicide attempt, or suicidal ideation.

The effectiveness of Mirtazapine in hospitalized depressed patients has not been adequately studied.

The efficacy of Mirtazapine in maintaining a response in patients with major depressive disorder for up to 40 weeks following 8 to 12 weeks of initial open-label treatment was demonstrated in a placebo-controlled trial. Nevertheless, the physician who elects to use Mirtazapine for extended periods should periodically re-evaluate the long-term usefulness of the drug for the individual patient

Atypical anti-depressant drugs

Mirtazapine, a piperazinoazepine tetracyclic antidepressant, enhances noradrenergic and serotonergic activity through blockade of central presynaptic adrenergic α2-receptors.

Adult: Initially, 15 mg daily; may be increased gradually depending on clinical response. Change dose at intervals of at least 1-2 wk. Usual effective dose: 15-45 mg daily given as single dose, preferably at bedtime, or in 2 divided doses.

Children: Safety and efficacy not established.

Geriatric: Use with caution.

Mirtazapine potentiates sedative effects with alcohol or benzodiazepines, increased plasma levels with potent CYP3A4 inhibitors (e.g. HIV-protease inhibitors, azole antifungals including ketoconazole, erythromycin, nefazodone), reduced plasma levels with carbamazepine and other inducers of CYP3A4 and increased bioavailability with cimetidine.

Mirtazapine is contraindicated in patients with hypersensitivity. Do not use with or within 2 weeks of stopping an MAOI; at least 1 week should elapse between discontinuing mirtazapine and initiating any drug which may provoke a serious reaction (e.g. phenelzine)

The most commonly reported adverse effects with mirtazapine are increase in appetite, weight gain, edema, drowsiness or sedation, dizziness, headache etc.

Mirtazapine Should not be used during pregnancy and lactation.
