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.
