    Abstract: A paliperidone double-layered osmotic pump controlled release tablet and the preparation method thereof are disclosed. The double-layered osmotic pump controlled release tablet comprises a rigid membrane, a push layer, a drug layer, an isolation layer and an aesthetic coating, wherein the rigid membrane contains a semi-permeable polymer, a porogen and/or a plasticizer and has one or more drug release orifices on one end, the push layer comprises an expanding material, an osmotic agent, a binder, a colorant and a lubricant, the drug layer contains a pharmaceutically active ingredient, a hydrophilic polymer, an osmotic agent, a colorant, a lubricant and an antistatic agent, the isolation layer is located between the inner surface of the rigid membrane and the push layer, and contains a hydrophilic polymer. The paliperidone double-layered osmotic pump controlled release tablet shows an increasing drug release rate at early stage and keeps a constant drug release rate at later stage.
