Problem:
LP, 35-year-old obese woman with a body mass index (BMI) of 32.4 kg/m2 and uncontrolled type 2 diabetes is starting on an atypical antipsychotic today for the management of schizophrenia. The pharmacist receives a call from LP's psychiatric nurse practitioner (NP), who has questions about drug selection. The NP mentions that LP's drug formulary lists aripiprazole, haloperidol, olanzapine, and quetiapine as tier 1, preferred options. The NP wants the pharmacist's opinion on which atypical antipsychotic may be most appropriate to prescribe. The NP would assume the pharmacist would recommend which medication?
