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.
Propantheline is a muscarinic receptor antagonist that competitively blocks the action of acetylcholine at postganglionic parasympathetic effector sites, resulting in anticholinergic effects such as decreased gastrointestinal motility and secretion.
2 mg orally twice daily; may increase to 4 mg daily in divided doses based on response.
15 mg orally three times daily before meals and 30 mg orally at bedtime.

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 is approximately 9 hours (range 6-12 hours) in patients with normal renal function; prolonged in renal impairment, requiring dose adjustment.
Renal: 77% (as metabolites, <1% unchanged); Fecal: 17%; Biliary: minor.
Renal excretion accounts for approximately 70% of elimination, with 30% as intact drug and 40% as inactive metabolites; biliary/fecal excretion contributes less than 5%.
