  ►    Mechanism of Drug Drug Interaction :  Mirtazapine should not be used with or within 2 weeks of stopping an MAOI; at least one week should elapse between stopping mirtazapine and starting any drug liable to provoke a serious reaction (e.g. phenelzine). Use of mirtazapine with alcohol or benzodiazepines may potentiate sedative effects. The cytochrome P450 isoenzyme CYP3A4 is involved in the metabolism of mirtazapine and caution is advised when mirtazapine is given with potent inhibitors of this isoenzyme such as HIV-protease inhibitors, azole antifungals including ketoconazole, erythromycin, and nefazodone; raised plasma levels of mirtazapine have been noted after use with ketoconazole. Conversely, carbamazepine and other inducers of CYP3A4 increased the clearance of mirtazapine and the dose of mirtazapine may need to be increased when given with these drugs. Cimetidine, which inhibits a range of cytochrome P450 isoenzymes, has more than doubled the bioavailability of mirtazapine; the dose of mirtazapine may need to be reduced if given with cimetidine.,
