What medication class is used to treat storage symptoms by reducing detrusor overactivity?

• A. Anticholinergics.
• B. Beta-adrenergic agonists.
• C. Alpha blockers.
• D. Diuretics.

Answer: (A)

Storage symptoms come from detrusor overactivity during filling, causing urge, frequency, and sometimes urge incontinence. Anticholinergic medications block muscarinic receptors on the detrusor muscle, mostly M3 receptors, which dampens involuntary bladder contractions as the bladder fills. With fewer contractions, the bladder can hold more urine, reducing urgency and frequency and improving urge incontinence. This makes anticholinergics a primary pharmacologic option for managing storage symptoms. Side effects to watch for include dry mouth, constipation, and, in older adults, potential cognitive effects. The other options address different problems (alpha blockers for obstruction, diuretics increase urine production) or use a different mechanism (beta-adrenergic agonists also help storage symptoms but via detrusor relaxation rather than blocking acetylcholine at muscarinic receptors).
