  • Patent number: 8114434
    Abstract: The invention provides an analgesic anti-inflammatory patch of a hydrophobic type for topical application containing, in a Pressure Sensitive Adhesive(PSA), diclofenac sodium, pyrrolidone or a derivative thereof, a polyhydric alcohol fatty acid ester, and an organic acid. The patch exerts the following effects: (1) diclofenac sodium is effectively and continuously released from a Pressure Sensitive Adhesive(PSA) and percutaneously absorbed, thereby attaining sustained, excellent pharmaceutical and pharmacological effects; (2) the patch per se has high tackiness and safety; and (3) diclofenac sodium remains stable in the Pressure Sensitive Adhesive(PSA).

  • Patent number: 5275825
    Abstract: Compressed molded preparations are disclosed. In the preparation coated granules of a pharmaceutical composition are compressed and molded together with non-coated component(s) containing 10% or more by weight of non-swelling polymers. According to the preparation there is little breakdown of the coating of coated granules at the time of compressing and molding, and the rate of disintegration, and in turn, the release rate of the pharmaceutical component, can be freely controlled or modulated.
