Atypical anti-psychotics:
Risperidone – 5-HT antagonist. SE: extrapyramidal adverse effects (in particular akathisia). Some weight gain, hyperprolactinemia. Patients switching from traditional antipsychotics may undergo cholinergic rebound (influenza-like symptoms). (First line drug)
Olanzapine – SE: drowsiness, weight gain, and dizziness. Temporary liver enzyme increases.
Quetiapine – Low potency, low risk of extrapyramidal adverse effects. SE: dizziness, dry mouth, and hypotension
Clozapine – SE: 2~3% neutropenia, 1% agranulocytosis, sedation, hypersalivation, weight gain, severe constipation, myoclonus and epileptic seizures. (Last line)
ECT can be used for psychotic depression when the patient fails to respond to pharmacotherapy.
