Benztropine is best described as which type of agent?

• A. Antiparkinsonian agent with strong anticholinergic properties
• B. Antimuscarinic for urinary incontinence
• C. Antipsychotic
• D. Skeletal muscle relaxant

Answer: (A)

Benztropine is best described as an antiparkinsonian agent with strong anticholinergic properties. It works by blocking muscarinic receptors in the central nervous system, especially in the basal ganglia, which helps restore the balance between dopamine and acetylcholine that is disrupted in Parkinson disease and in drug-induced extrapyramidal symptoms. By reducing acetylcholine activity in these pathways, it helps lessen tremor and rigidity and improves motor control. Because of its anticholinergic effects, it can cause dry mouth, constipation, blurred vision, urinary retention, and confusion, which is why it requires careful use in older adults. It is not primarily used for urinary incontinence, nor is it an antipsychotic or a skeletal muscle relaxant, so those descriptions don’t fit as well.
