Delivery System Components and Performance Paliperidone Extended-Release Tablets uses osmotic pressure to deliver paliperidone at a controlled rate. The delivery system, which resembles a round-shaped tablet in appearance, consists of an osmotically active bilayer core surrounded by a subcoat and semipermeable membrane. The bilayer core is composed of two drug layers containing the drug and excipients, and a push layer containing osmotically active components. There is two precision laser-drilled orifice on the drug-layer side of the tablet. Each tablet strength has a different colored water-dispersible overcoat and print markings. In an aqueous environment, such as the gastrointestinal tract, the water-dispersible color overcoat erodes quickly. Water then enters the tablet through the semipermeable membrane that controls the rate at which water enters the tablet core, which, in turn, determines the rate of drug delivery. The hydrophilic polymers of the core hydrate and swell, creating a gel containing paliperidone that is then pushed out through the tablet orifice. The biologically inert components of the tablet remain intact during gastrointestinal transit and are eliminated in the stool as a tablet shell, along with insoluble core components. Image
