  • 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: 5879702
    Abstract: A non-steroidal analgesic anti-inflammatory adhesive preparation rendered by coating one surface of support with an adhesive containing S-(+)-2-(2-fluoro-4-biphenylyl)propionic acid and a styrene-isoprene-styrene block copolymer or S-(+)-2-(2-fluoro-4-biphenylyl) propionic acid and a modified copolymer in which methylmethacrylate is allowed to graft-polymerize on said copolymer, or with an adhesive containing S-(+)-2-(2-fluoro-4-biphenylyl) propionic acid, sodium carboxymethyl cellulose and sodium polyacrylate.
