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.
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.
4 mg orally once daily; may be reduced to 2 mg once daily based on tolerability.
Glycopyrronium tosylate: 1-2 mg orally 2-3 times daily; maximum 8 mg daily.

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: 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.
Approximately 77% eliminated in urine (primarily as metabolites, <1% unchanged) and 17% in feces.
Renal: 85% unchanged; biliary/fecal: ~5% as metabolites and unchanged drug; elimination primarily via glomerular filtration and tubular secretion.
