Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Dicyclomine is a muscarinic acetylcholine receptor antagonist that blocks the action of acetylcholine at postganglionic parasympathetic effector sites, reducing gastrointestinal smooth muscle spasms and hypermotility.
Trospium is an antimuscarinic agent that competitively inhibits acetylcholine at muscarinic receptors, reducing bladder detrusor muscle contractions.
20 mg orally four times daily; may increase to 40 mg four times daily if tolerated. Immediate-release: 20 mg orally every 6 hours. Extended-release: 20 mg orally twice daily.
60 mg orally once daily, taken with a full glass of water at least 1 hour before meals. Extended-release capsule.

1.9 to 3 hours (terminal elimination half-life); clinical context: short half-life supports multiple daily dosing for spasm relief.
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.
Primarily renal (approximately 60% as unchanged drug and metabolites) and fecal (about 40% via biliary elimination).
Primarily renal excretion (70-80% as unchanged drug and active metabolite); approximately 10% fecal; 5-10% biliary.
