DARBID vs TOLTERODINE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Antimuscarinic agent; competitively blocks acetylcholine at muscarinic receptors, reducing gastrointestinal motility and secretions.
Competitive antagonist of muscarinic acetylcholine receptors (M1, M2, M3, M4, M5), with selectivity for the M3 receptor subtype involved in detrusor muscle contraction, reducing bladder smooth muscle contractility and increasing bladder capacity.
5 mg orally three times daily, before meals. May be increased to 20 mg per day if necessary.
2 mg PO twice daily; may reduce to 1 mg twice daily if tolerated.

Terminal elimination half-life is approximately 1.5 to 2 hours in adults, requiring frequent dosing for sustained anticholinergic effect.
Clinical Note
moderateTolterodine + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Tolterodine."
Clinical Note
moderateTolterodine + Cyclosporine
"The metabolism of Cyclosporine can be decreased when combined with Tolterodine."
Clinical Note
moderateTolterodine + Fluconazole
"The metabolism of Fluconazole can be decreased when combined with Tolterodine."
Clinical Note
moderateTolterodine + Clotrimazole
Terminal elimination half-life is 2-4 hours in extensive CYP2D6 metabolizers; increased to 4-10 hours in poor metabolizers or with CYP3A4 inhibitors.
Renal: ~50% unchanged; biliary/fecal: ~50% as metabolites and unchanged drug.
Primarily hepatic metabolism via CYP2D6 and CYP3A4; renal excretion accounts for <5% of unchanged drug; ~80% excreted in urine as metabolites, ~20% in feces.
