Question

Quizplus · Accepted Answer

Medications used to treat extrapyramidal side effects from antipsychotic medications and drugs for Parkinson's disease work by increasing the amount of dopamine at the receptor sites in the basal ganglia. This compensates for the dopamine deficiency seen in Parkinson's disease and counteracts the dopamine blockade caused by antipsychotic medications, which can lead to extrapyramidal symptoms.
