Olanzapine 75% was most common antipsychotic drug prescribed followed by risperidone 10.7%. Haloperidol 9.6%, fluphenazine 3.7% and chlorpromazine 1% were the other antipsychotics prescribed. Atypical antipsychotics 85.7% were commonly prescribed than conventional ones 4.3%. Concomitant drugs prescribed were anticholinergics, antihistaminics, sedative-hypnotics, antidepressants, mood stabilizers, antiulcer drugs and vitamin B complexes.
