PHOTOSTABILIZED TOPICAL FORMULATIONS OF KETOPROFEN CONTAINING TWO UV FILTERS

摘要

The invention relates to topical pharmaceutical formulations containing ketoprofen or its S(+) isomer dexketoprofen or mixtures of the two isomers, together with two UV filters, preferably octyl methoxy cinnamate and phenyl benzimidazol sulphonic acid, and an antioxidant, preferably butyl hydroxy toluene (BHT). The formulations enable a photostability of the active principle, have no, or very low, irritant effect on the skin, are well tolerated, and present an adequate penetration through the skin.
