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.
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.
20 mg orally twice daily, with or without food. Maximum dose 20 mg twice daily.
5 mg orally once daily, may increase to 10 mg once daily if tolerated.

Terminal elimination half-life is approximately 12–20 hours in healthy adults, allowing twice-daily dosing.
Terminal elimination half-life is approximately 45-68 hours (mean ~55 hours) in healthy adults, allowing once-daily dosing.
Primarily renal (approximately 60% as unchanged drug and metabolites); biliary/fecal elimination accounts for ~30%.
Primarily renal: ~69% as metabolites (including active metabolite 4R-hydroxy solifenacin) and ~7% as unchanged drug. Fecal excretion accounts for ~23% (mainly as metabolites).
