Drugs Similar to OXYBUTYNIN CHLORIDE EXTENDED RELEASE

Oxybutynin chloride USP is an antispasmodic, muscarinic antagonist. Each oxybutynin chloride extended-release tablet USP 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-butynylphenylcyclohexylglycolate 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 solid with a molecular weight of 393.9. It is readily soluble in water and acids, but relatively insoluble in alkalis. Oxybutynin chloride extended-release tablet, USP also contains the following inert ingredients: polyethylene oxide, hypromellose, sodium chloride, butylated hydroxytoluene, ferric oxide (yellow), ferric oxide (red), ferric oxide (black), colloidal silicon dioxide, magnesium stearate, cellulose acetate, polyethylene glycol, titanium dioxide, lactose monohydrate, triacetin, shellac, and propylene glycol. System Components and Performance Oxybutynin chloride extended-release tablets USP uses osmotic pressure to deliver oxybutynin chloride at a controlled rate over approximately 24 hours. The system, which resembles a conventional tablet in appearance, comprises an osmotically active bilayer core surrounded by a semipermeable membrane. The bilayer core is composed of a drug layer containing the drug and excipients, and a push layer containing osmotically active components. There is a precision-laser drilled orifice in the semipermeable membrane on the drug-layer side of the tablet. In an aqueous environment, such as the gastrointestinal tract, water permeates through the membrane into the tablet core, causing the drug to go into suspension and the push layer to expand. This expansion pushes the suspended drug out through the orifice. The semipermeable membrane controls the rate at which water permeates into the tablet core, which in turn controls the rate of drug delivery. The controlled rate of drug delivery into the gastrointestinal lumen is thus independent of pH or gastrointestinal motility. The function of oxybutynin chloride extended-release tablets depends on the existence of an osmotic gradient between the contents of the bilayer core and the fluid in the gastrointestinal tract. Since the osmotic gradient remains constant, drug delivery remains essentially constant. The biologically inert components of the tablet remain intact during gastrointestinal transit and are eliminated in the feces as an insoluble shell.

System Components and Performance Oxybutynin chloride extended-release tablet, USP uses a pH-independent hydrophilic matrix and pH dependent enteric coating to deliver oxybutynin chloride, USP at a controlled rate over approximately 24 hours. The oxybutynin chloride extended-release tablet, USP comprises of an inner core made of the drug, rate controlling pH independent polymer and other excipients. The tablet core is then coated with pH dependent enteric coating polymer. When tablets will be exposed to an acidic environment such as the stomach, the drug release will be minimal due to outer enteric coating of the pH dependent polymer. The outer enteric coating upon reaching an environment of pH 5.5 and above will start to dissolve and the polymer in the inner core tablet will hydrate to form a gel layer and the drug releases via diffusion process. 1

System Components and Performance Oxybutynin chloride extended-release tablet, USP uses a pH-independent hydrophilic matrix and pH dependent enteric coating to deliver oxybutynin chloride, USP at a controlled rate over approximately 24 hours. The oxybutynin chloride extended-release tablet, USP comprises of an inner core made of the drug, rate controlling pH independent polymer and other excipients. The tablet core is then coated with pH dependent enteric coating polymer. When tablets will be exposed to an acidic environment such as the stomach, the drug release will be minimal due to outer enteric coating of the pH dependent polymer. The outer enteric coating upon reaching an environment of pH 5.5 and above will start to dissolve and the polymer in the inner core tablet will hydrate to form a gel layer and the drug releases via diffusion process. 1
