Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Competitive antagonist of muscarinic acetylcholine receptors (M1, M2, M3) in the gastrointestinal tract, producing antispasmodic effects by reducing smooth muscle contractions.
Trospium is an antimuscarinic agent that competitively inhibits acetylcholine at muscarinic receptors, reducing bladder detrusor muscle contractions.

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.
