GLYCORT vs OXYBUTYNIN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Glucocorticoid receptor agonist; modulates gene expression to produce anti-inflammatory and immunosuppressive effects.
Oxybutynin is an anticholinergic agent that competitively antagonizes muscarinic acetylcholine receptors (M1, M2, M3 subtypes) in the bladder detrusor muscle, inhibiting involuntary contractions and increasing bladder capacity.
Intravenous: 2 mg/kg every 12 hours; Oral: 20 mg twice daily.
5 mg orally 2-3 times daily; maximum 5 mg 4 times daily. Extended-release: 5-10 mg orally once daily; maximum 30 mg/day. Transdermal: 3.9 mg/day patch applied every 3-4 days. Topical gel: 1 g (3 pumps) applied once daily.

Clinical Note
moderateOxybutynin + Sulfisoxazole
"The metabolism of Sulfisoxazole can be decreased when combined with Oxybutynin."
Clinical Note
moderateOxybutynin + Erythromycin
"The metabolism of Erythromycin can be decreased when combined with Oxybutynin."
Clinical Note
moderateOxybutynin + Cyclosporine
"The metabolism of Cyclosporine can be decreased when combined with Oxybutynin."
Clinical Note
moderateOxybutynin + Fluconazole
3.5 hours (terminal); prolonged in hepatic impairment (up to 8 hours) and severe renal impairment (up to 6 hours)
Terminal half-life: 12-13 hours (range 7-20 hours) in healthy adults. In elderly, half-life may be prolonged due to reduced clearance.
Renal: 70% as unchanged drug; biliary/fecal: 25% (metabolites); 5% other
Primarily hepatic metabolism; less than 1% excreted unchanged in urine. Metabolites are mainly excreted renally (50%) and fecally (40%).
