  • Transdermal preparation for external use containing nonsterioidal antiinflammatory/analgesic agent
    Publication number: 20100311700
    Abstract: A transdermal preparation for external use which contains a photosensitive NSAID and a UV blocker having a high ability to migrate into the skin. Thus, it becomes possible to ensure, in a transdermal preparation for external use containing a NSAID, the inhibition of the onset of light-induced non-immunological or immunological skin symptoms by the above-described component.

  • EXTERNAL PREPARATION FOR PERCUTANEOUS ADMINISTRATION CONTAINING NONSTEROIDAL ANTI-INFLAMMATORY ANALGESIC
    Publication number: 20100240758
    Abstract: An external preparation for percutaneous administration which contains a light-sensitive nonsteroidal anti-inflammatory analgesic and a UVA-shielding agent which inhibits the analgesic to cause light toxicity and a light allergy. This external preparation for percutaneous administration, which contains a nonsteroidal anti-inflammatory analgesic, can be prevented, with higher certainty, from causing the hypersensitivity to light attributable to light toxicity and a light allergy.
