Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Trospium chloride is an antimuscarinic agent that competitively inhibits acetylcholine at muscarinic receptors, thereby reducing detrusor muscle contractions and increasing bladder capacity.
Competitive antagonist of muscarinic acetylcholine receptors (M1, M2, M3, M4, M5) with relative selectivity for the bladder over salivary glands. Reduces detrusor muscle contractility and bladder pressure.
20 mg orally twice daily, with or without food. Maximum dose 20 mg twice daily.
2 mg orally twice daily. May be reduced to 1 mg orally twice daily based on tolerability.

Terminal elimination half-life is approximately 12–20 hours in healthy adults, allowing twice-daily dosing.
Terminal elimination half-life is 2-3 hours in extensive metabolizers (CYP2D6) and approximately 9 hours in poor metabolizers. In clinical context, dosing interval is adjusted in poor metabolizers (e.g., 2 mg twice daily reduced to 2 mg once daily).
Primarily renal (approximately 60% as unchanged drug and metabolites); biliary/fecal elimination accounts for ~30%.
Renal (77%) and fecal (17%): approximately 14% as unchanged tolterodine, 51% as the active 5-hydroxymethyl metabolite, and 12% as other metabolites. Biliary excretion contributes minimally.
