Summary not available yet.

Oxybutynin chloride extended-release tablets are an antispasmodic, muscarinic antagonist. Each oxybutynin chloride extended-release tablets contains 5 mg, 10 mg, or 15 mg of oxybutynin chloride USP, formulated as a once-a-day controlled-release tablet for oral administration. Oxybutynin chloride is administered as a racemate of R-and S-enantiomers. Chemically, oxybutynin chloride is d,l (racemic) 4-diethylamino-2-butynyl phenylcyclohexylglycolate hydrochloride. The empirical formula of oxybutynin chloride is C 22 H 31 NO 3 •HCl. Its structural formula is: Oxybutynin chloride, USP is a white crystalline, practically odorless powder with a molecular weight of 393.95. It is freely soluble in water and in alcohol, very soluble in methanol and in chloroform, soluble in acetone, slightly soluble in ether and very slightly soluble in hexane. Oxybutynin chloride extended-release tablet, USP also contains the following inactive ingredients: alginic acid, hydrogenated castor oil, hypromellose, lactose monohydrate, magnesium stearate, methacrylic acid copolymer dispersion, microcrystalline cellulose, povidone, talc and triethyl citrate. The product complies the USP Dissolution Test 8 System Components and Performance Oxybutynin chloride extended-release tablet uses an enteric coated hydrophilic hydrogel matrix to deliver oxybutynin chloride at controlled rate over approximately 24 hours by diffusion mechanism. The system comprises of a core, which contains the drug, rate controlling hydrogel and other excipients. The core is surrounded by a partially or complete pH dependent membrane. Hence, when the drug reaches the acidic medium, in stomach minimal drug release will occur and when it reaches an environment of pH 5.5 and above, the outer membrane will be dissolved exposing the inner core. This inner core will partially hydrate to form a gel layer and the drug release will occur via diffusion mechanism from a gel layer and subsequently through gel erosion.

Oxybutynin chloride extended-release tablets, USP also contains the following inert ingredients: hypromellose, hydrogenated vegetable oil, microcrystalline cellulose, lactose monohydrate, povidone, colloidal silicon dioxide, magnesium stearate, methacrylic acid and ethyl acrylate co-polymer dispersion, triethyl citrate, talc, titanium dioxide, polyethylene glycol/macrogol, iron oxide yellow non-irradiated, isopropyl alcohol and iron oxide red non-irradiated. The ink contains shellac glaze (modified), black iron oxide non-irradiated, N-butyl alcohol, propylene glycol and ammonium hydroxide. Chemical Structure System Components and Performance Oxybutynin chloride extended-release tablets, USP uses an enteric coated hydrophilic hydrogel matrix to deliver oxybutynin chloride at controlled rate over approximately 24 hours by diffusion mechanism. The system comprises of a core, which contains the drug, rate controlling hydrogel and other excipients. The core is surrounded by a partially or complete pH dependent membrane. Hence, when the drug reaches the acidic medium, in stomach minimal drug release will occur and when it reaches an environment of pH 5.5 and above, the outer membrane will be dissolved exposing the inner core. This inner core will partially hydrate to form a gel layer and the drug release will occur via diffusion mechanism from a gel layer and subsequently through gel erosion. Meets USP Dissolution Method 4. FDA approved acceptance criteria differs from the USP acceptance criteria.
