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.
Competitive antagonist of muscarinic acetylcholine receptors (M1, M2, M3), inhibiting parasympathetic nerve impulses. Blocks the action of acetylcholine at autonomic effector sites innervated by postganglionic cholinergic nerves, reducing salivary, bronchial, and gastric secretions, and relaxing smooth muscle.
2 mg orally twice daily; may increase to 4 mg daily in divided doses based on response.
Glycopyrronium tosylate: 1-2 mg orally 2-3 times daily; maximum 8 mg daily.

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: 0.6–1.2 hours in adults with normal renal function; prolonged in renal impairment (up to 3–4 hours). Clinically, duration of action is longer than half-life due to high receptor affinity.
Renal: 77% (as metabolites, <1% unchanged); Fecal: 17%; Biliary: minor.
Renal: 85% unchanged; biliary/fecal: ~5% as metabolites and unchanged drug; elimination primarily via glomerular filtration and tubular secretion.
