Question

Quizplus · Accepted Answer

Many effective antischizophrenic drugs are D2 blockers, which means they block dopamine receptors in the brain. This action helps to reduce the hyperactivity in the dopamine system that is thought to contribute to schizophrenia symptoms. There is no evidence to suggest that these drugs are effective against Parkinson's disease, and they are not D2 agonists (which would stimulate dopamine receptors rather than block them). Therefore, option C is the best choice.
