Oxybutynin chloride USP is a white crystalline solid with a molecular weight of It is readily soluble in water and acids, but relatively insoluble in alkalis. Oxybutynin chloride extended-release tablet, USP contains the following inert ingredients: 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. USP Dissolution Test is pending.
