Mechanism of action

Tolterodine selectively antagonizes M2 and M3 muscarinic receptors in the detrusor muscle of the bladder. By blocking these receptors, it prevents acetylcholine-mediated bladder contractions, thereby increasing bladder capacity and reducing the frequency of micturition. The extended-release formulation provides sustained therapeutic effect over 24 hours.
