  • Publication number: 20070280980
    Abstract: A percutaneous pharmaceutical preparation for external use containing a nonsteroidal antiinflammatory analgesic. It is effective in inhibiting, with higher certainty, the hypersensitivity to light attributable to the phototoxicity and photoallergy of nonsteroidal antiinflammatory analgesics. It can sufficiently produce the effects of the nonsteroidal antiinflammatory analgesic while preventing the pharmaceutical preparation from being altered with time by the incorporation of a dibenzoylmethane derivative as a UVA absorber. The percutaneous pharmaceutical preparation for external use comprises, as essential ingredients, a nonsteroidal antiinflammatory analgesic, a dibenzoylmethane derivative, and one or more members selected among polyhydric alcohol/fatty acid esters, higher fatty acid esters, and crotamiton.
