Abstract:
Research on psychoactive drugs: antianxiety, antidepressant, and antipsychotic was reviewed. The drug families and their usual side effects were described. Proliferation of drug use, polypharmacy, and tardive dyskinesia were seen as areas of concern; advances in biological explanations of schizophrenia and manic-depressive disorders, and increasing knowledge about the brain's neurotransmitters brightened the investigative efforts.
