Which class is used to treat bladder spasm and involuntary muscle spasms and can cause dry mouth and blurred vision?

• A. Anticoagulants
• B. Anticholinergics
• C. Anti-inflammatory
• D. Antidepressants

Answer: (B)

Anticholinergic drugs work by blocking acetylcholine at muscarinic receptors, which reduces smooth muscle contractions. This makes them effective for calming bladder spasms and other involuntary muscle spasms because the detrusor muscle of the bladder doesn’t contract as readily. The same receptor blockade also decreases secretions and affects the eye’s ability to focus, leading to dry mouth and blurred vision—well-known side effects of this drug class. Other options don’t target these muscarinic pathways to control bladder or involuntary muscle activity, so they don’t fit this use or side-effect profile as well.
