Final answer:
The cause of acute extrapyramidal symptoms (EPS) in a schizophrenic patient taking Haldol 10 (haloperidol) is likely due to the medication's effect on dopamine neurotransmission in the brain.
Step-by-step explanation:
The cause of acute extrapyramidal symptoms (EPS) in a schizophrenic patient taking Haldol 10 (haloperidol) is likely due to the medication's effect on dopamine neurotransmission in the brain. Haldol is an antipsychotic medication that works by blocking dopamine receptors, leading to a decrease in dopamine neurotransmission. However, this decrease in dopamine can cause side effects, such as EPS, which are similar to the symptoms seen in Parkinson's disease.
