Loxapine is being rediscovered as a well-tolerated first-generation antipsychotic (FGA).

Iloperidone is not recommended as a first-choice antipsychotic due to twice-daily dosing, slow titration requirements, QT prolongation (similar to ziprasidone), dizziness, moderate weight gain, increased blood sugar, and overall weaker efficacy compared to other agents.

Cobenfy is a novel antipsychotic that acts through the muscarinic acetylcholine system rather than the traditional dopamine pathways.

Tried and true, risperidone’s moderate side effect profile has led to its wide use, and many clinicians consider it their antipsychotic of choice for first-episode psychotic disorders. 

Many consider olanzapine to be more effective than other antipsychotics and just below clozapine in overall efficacy. Its strong effectiveness, once-daily dosing, and low QT-prolongation risk are appealing.
