antipsychotics Flashcards
(PH-1) List the prototype antipsychotic drugs for the following classes of drugs: phenothiazines, thioxanthenes, and butyrophenones. (PH-2) Describe the mechanism of action of the prototype phenothiazine, thioxanthene, and butyrophenone drugs, categorize them according to potency, and describe their clinical uses and side effects. (PH-3) Describe the motor fluctuations seen both early and late during treatment with the first generation (Typical) antipsychotics. (PH-4) List the prototype atypi
