Ans: c (Moclobemide) Ref: Ahuja, 6th ed,p. Katzung Pharmacology, 10th ed,p. 475Moclobemide is a reversible and selective MAO-A inhibitor.MAO is a mitochondrial enzyme involved in oxidative deamination of biogenic amines(Adr,NA,DA,5-HT)ADVERSE EFFECTSHeadache, drowsiness, dry mouth, weight gain, postural hypotension, sexual disturbances, interactions with tyramine containing foods.Serotonin syndrome- It is a condition precipitated when MAO inhibitors are given with serotonin agonists, especially antidepressants of the selective serotonin reuptake inhibitor class (SSRIs). It occurs when overdose with a single drug, or concurrent use of several drugs, results in excess serotonergic activity in the central nervous system .Clinical features are hypertension, hyperreflexia, tremor, clonus, hyperthermia, hyperactive bowel sounds, diarrhoea, mydriasis, agitation, coma.Classification of anti-depressants1.TRICYCLIC ANTIDEPRESSANTS (TCAS)Imipramine, Amitriptyline, Clomipramine, Nortriptyline, Mianserin, Amoxapine2.
