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.
Solifenacin is a competitive muscarinic receptor antagonist. It binds selectively to M3 muscarinic receptors, inhibiting acetylcholine action on smooth muscle of the urinary bladder, reducing detrusor overactivity and increasing bladder capacity.
60 mg orally once daily, taken with a full glass of water at least 1 hour before meals. Extended-release capsule.
5 mg orally once daily, may increase to 10 mg once daily if tolerated.

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 approximately 45-68 hours (mean ~55 hours) in healthy adults, allowing once-daily dosing.
Primarily renal excretion (70-80% as unchanged drug and active metabolite); approximately 10% fecal; 5-10% biliary.
Primarily renal: ~69% as metabolites (including active metabolite 4R-hydroxy solifenacin) and ~7% as unchanged drug. Fecal excretion accounts for ~23% (mainly as metabolites).
