Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Tolterodine is a competitive muscarinic receptor antagonist. It blocks acetylcholine binding at muscarinic receptors (M1–M5), reducing detrusor muscle contraction and bladder pressure, thereby increasing bladder capacity and decreasing urinary frequency.
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.
4 mg orally once daily; may be reduced to 2 mg once daily based on tolerability.
15 mg orally three times daily before meals and 30 mg orally at bedtime.

Terminal elimination half-life is approximately 7 hours (range 5-10 hours) for the extended-release formulation, allowing once-daily dosing.
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.
Approximately 77% eliminated in urine (primarily as metabolites, <1% unchanged) and 17% in feces.
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%.
