Which of the following is an antimuscarinic used for urinary incontinence with strong anticholinergic properties?

• A. Darifenacin
• B. Benztropine
• C. Clozapine
• D. Scopolamine

Answer: (A)

Antimuscarinics for urinary incontinence work by blocking acetylcholine at muscarinic receptors in the bladder to stop overactive detrusor contractions. Darifenacin is used specifically for overactive bladder/urge incontinence and is known for strong anticholinergic activity, which is the property highlighted in this question. Among the options, it’s the one prescribed for urinary symptoms. Benztropine is used for Parkinson’s-related symptoms, scopolamine for motion sickness, and clozapine is an antipsychotic with anticholinergic effects but not for bladder incontinence. So darifenacin best fits the description.
