What is Gelnique?
Gelnique is a prescription medicine used to treat the symptoms of overactive bladder urge urinary incontinence (a strong need to urinate with leaking or wetting accidents), Urgency (a strong need to urinate right away), Frequency (need to urinate often).
Oxybutynin is an antispasmodic, antimuscarinic agent. GELNIQUE (oxybutynin chloride) is a clear and colorless hydroalcoholic gel containing 100 mg oxybutynin chloride per gram of gel. GELNIQUE is available in a metered-dose pump that dispenses 30 metered 1 gram doses or in a 1 gram (1.14 mL) unit dose. Each dose contains 100 mg oxybutynin chloride. Oxybutynin is delivered as a racemate of R- and S- isomers. Chemically, oxybutynin chloride is d, l (racemic) 4-(Diethylamino)-2-butynyl (±)-α-phenylcyclohexaneglycolate hydrochloride.
The empirical formula of oxybutynin is C22H31NO3•HCl. Its structural formula is:
Oxybutynin chloride is a white powder with a molecular weight of 393.95.
Inactive ingredients in GELNIQUE are alcohol, USP; glycerin, USP; hydroxypropyl cellulose, NF; sodium hydroxide, NF; and purified water, USP.
Mechanism of Action
Oxybutynin acts as a competitive antagonist of acetylcholine at postganglionic muscarinic receptors, resulting in relaxation of bladder smooth muscle. Oxybutynin is a racemic (50:50) mixture of R- and S- isomers. Antimuscarinic activity resides predominantly with the R- isomer. The active metabolite, N-desethyloxybutynin, has pharmacological activity on the human detrusor muscle that is similar to that of oxybutynin in in vitro studies.
