Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Anticholinergic; competitively blocks muscarinic acetylcholine receptors, inhibiting parasympathetic impulses.
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.
Adults: 50 mg orally four times daily, before meals and at bedtime.
4 mg orally once daily; may be reduced to 2 mg once daily based on tolerability.

Terminal elimination half-life is approximately 2.5–3 hours in adults with normal renal function. In elderly or those with renal impairment, half-life may be prolonged to 6–8 hours, requiring dose adjustment.
Terminal elimination half-life is approximately 7 hours (range 5-10 hours) for the extended-release formulation, allowing once-daily dosing.
BANTHINE (methantheline) is primarily eliminated via renal excretion (approximately 70% unchanged) with the remainder as metabolites. Biliary/fecal elimination accounts for less than 15%. Total recovery in urine and feces is nearly complete.
Approximately 77% eliminated in urine (primarily as metabolites, <1% unchanged) and 17% in feces.
