Tolterodine is best described as which type?

• A. Antimuscarinic for urinary incontinence
• B. Antipsychotic
• C. Antiparkinsonian
• D. Skeletal muscle relaxant

Answer: (A)

Tolterodine is an antimuscarinic (anticholinergic) medication that works by blocking muscarinic receptors in the bladder, particularly the M3 subtype. By inhibiting acetylcholine signaling in the detrusor muscle, it reduces involuntary bladder contractions and increases bladder capacity, helping to relieve symptoms of overactive bladder and urge urinary incontinence.

This is not an antipsychotic, which targets dopamine or other neurotransmitter systems for psychiatric conditions; nor is it an antiparkinsonian, which addresses motor symptoms of Parkinson’s disease; and it’s not a skeletal muscle relaxant, which affects skeletal muscle or spasm.
