GELNIQUE vs GELNIQUE 3%
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
GELNIQUE (oxybutynin) is a competitive antagonist of muscarinic acetylcholine receptors (M1, M2, M3), primarily M3 receptors in the detrusor muscle of the bladder, reducing bladder contractions and increasing bladder capacity.
Oxybutynin is a competitive antagonist of muscarinic acetylcholine receptors (M1, M2, M3 subtypes), primarily M3 receptors, leading to relaxation of detrusor smooth muscle and inhibition of involuntary bladder contractions.
Apply 1 gram (1 sachet) of gel once daily to clean, dry, intact skin on the abdomen, upper arms, shoulders, or thighs. Each gram contains 100 mg oxybutynin.
Apply 1 gram (4 metered actuations) of gel topically to dry intact skin on abdomen, upper thighs, or upper arms once daily.

Terminal elimination half-life is approximately 12-13 hours for oxybutynin and 8-10 hours for the active metabolite N-desethyloxybutynin, allowing for once-weekly transdermal dosing.
Terminal half-life: 7.5 hours (range 5-10 h); clinically, steady-state achieved in 2 days
Approximately 75% of the dose is excreted renally as unchanged drug and metabolites (primarily N-desethyloxybutynin), with about 25% excreted in feces via biliary elimination.
Renal: 70% as unchanged drug; fecal: 20% as metabolites; biliary: 10%
