Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Trospium is an antimuscarinic agent that competitively inhibits acetylcholine at muscarinic receptors, reducing bladder detrusor muscle contractions.
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.
60 mg orally once daily, taken with a full glass of water at least 1 hour before meals. Extended-release capsule.
2 mg orally twice daily. May be reduced to 1 mg orally twice daily based on tolerability.

Terminal elimination half-life is approximately 7-10 hours in patients with normal renal function; prolonged to 20-30 hours in moderate to severe renal impairment.
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 excretion (70-80% as unchanged drug and active metabolite); approximately 10% fecal; 5-10% biliary.
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.
