Benztropine is used in Parkinson's disease to affect which neurotransmitter?

Benztropine is primarily used in the treatment of Parkinson's disease to address imbalances in the neurotransmitter acetylcholine. In Parkinson's disease, there's a deficiency of dopamine due to the degeneration of dopaminergic neurons in the substantia nigra. This imbalance between dopamine and acetylcholine leads to the hallmark symptoms of the disease, such as tremors, rigidity, and bradykinesia.

Benztropine, which is an anticholinergic agent, works by blocking the action of acetylcholine in the brain, thereby helping to restore a more favorable balance between dopamine and acetylcholine. This can lead to a reduction in some of the motor symptoms associated with Parkinson's disease.

While dopamine is indeed central to the pathology of Parkinson's, the use of benztropine specifically targets the actions of acetylcholine to alleviate symptoms. Thus, the correct association of benztropine with its action on acetylcholine is crucial to understand its therapeutic role in managing Parkinson's disease symptoms.
