## **Core Concept**
The question tests understanding of managing extrapyramidal side effects (EPS) associated with antipsychotic medications, specifically typical antipsychotics like haloperidol. Haloperidol is a dopamine D2 receptor antagonist used to treat schizophrenia but can cause EPS due to its mechanism of action. The developed symptoms of parkinsonism are a type of EPS.

## **Why the Correct Answer is Right**
The correct approach to treating drug-induced parkinsonism involves using anticholinergic medications. These drugs help alleviate the symptoms of parkinsonism by correcting the imbalance in neurotransmitters (acetylcholine and dopamine) in the basal ganglia. Among the options provided, **Benzatropine (C)** is an anticholinergic agent commonly used to treat EPS, including drug-induced parkinsonism. It works by blocking acetylcholine receptors in the central nervous system, thereby reducing the cholinergic activity that is relatively increased compared to dopaminergic activity in EPS.

## **Why Each Wrong Option is Incorrect**
- **Option A:** This option is blank and cannot be evaluated.
- **Option B:** This option is blank and cannot be evaluated.
- **Option D:** This option is blank and cannot be evaluated.

## **Clinical Pearl / High-Yield Fact**
A key point to remember is that anticholinergic agents like benzatropine are effective in treating EPS but are not typically used for long-term management due to potential side effects, such as dry mouth, blurred vision, urinary retention, and cognitive impairment. Also, it's crucial to note that while these agents alleviate EPS, they do not treat the underlying psychiatric condition.

## **Correct Answer:** . Benzatropine
