Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive muscarinic receptor antagonist, primarily targeting M3 receptors in the bladder, reducing detrusor muscle contractions and increasing bladder capacity.
Tropium chloride is a quaternary ammonium compound that acts as a competitive antagonist at muscarinic acetylcholine receptors (M1, M2, M3), thereby reducing smooth muscle tone in the bladder, decreasing detrusor overactivity, and increasing bladder capacity.
2 mg orally twice daily; may increase to 4 mg daily in divided doses based on response.
20 mg orally twice daily, extended-release 60 mg orally once daily in the morning.

Terminal half-life 6.9 hours (range 4-10 hours) for tolterodine; 7.7 hours (range 5-13 hours) for active 5-hydroxymethyl metabolite; prolonged in hepatic impairment (up to 3-fold).
Terminal elimination half-life: 10-20 hours (mean 14 hours); clinical context: supports twice-daily dosing
