Used primarily to treat overactive bladder (OAB), this compound helps reduce symptoms such as frequent urination, urgency, and urinary incontinence. It works by selectively blocking muscarinic receptors in the bladder, particularly the M3 subtype, which are responsible for smooth muscle contraction. By inhibiting these receptors, it allows the bladder muscle to relax, increasing bladder capacity and decreasing involuntary contractions. It is taken orally in extended-release formulations, providing sustained symptom control with once-daily dosing. Due to its selectivity, it may cause fewer central nervous system and dry mouth side effects compared to non-selective anticholinergics.
