Antipsychotic agents: a clinical update.

Antipsychotic agents have many indications and are frequently used. All physicians, regardless of their subspecialty, will most likely treat patients who receive these drugs. This article is designed to help nonpsychiatric physicians use antipsychotics appropriately. The indications, recommended dosages, side effects, and drug interactions of antipsychotic medications are reviewed. Receptor binding data are used to help predict the side-effect profile of these agents. Knowledge of these side effects and of the patient's medical condition helps the physician select a drug that the patient can tolerate. Management of overdose situations is discussed.
