Quizplus · Accepted Answer

Chlorpromazine is a typical antipsychotic drug that can cause extrapyramidal side effects, which are a group of movement disorders that include dystonia, akathisia, Parkinsonism, and tardive dyskinesia. The addition of an antiparkinsonian drug, such as benztropine or trihexyphenidyl, may be necessary to alleviate these symptoms. Antihypertensive drugs are used to treat high blood pressure, anticonvulsant drugs to treat seizures, and antiemetic drugs to treat nausea and vomiting.
