Final answer:
Antipsychotic drugs block dopamine receptors to reduce symptoms of schizophrenia.
Step-by-step explanation:
Schizophrenia is a serious mental illness that is associated with overactive dopamine neurotransmission. Antipsychotic drugs are used to treat these symptoms by blocking dopamine receptors, which prevents dopamine from signaling information to adjacent neurons. By reducing dopamine activity, these drugs can help alleviate psychotic symptoms such as hallucinations and delusions.
