Phloretin and 6-ketocholestanol are penetration enhancers for percutaneous delivery of certain topically applied drugs. In the present study some physicochemical experiments have been performed to elucidate the mechanism of action of phloretin and 6-ketocholestanol. The penetration enhancing effect of phloretin

The ability of 6-ketocholestanol to increase the skin permeation of the prodrug aminolevulinic acid (5-ALA) was investigated. 6-Ketocholestanol was incorporated together with 5-ALA in four different formulations. Preparations used were a liquid solution/suspension of 5-ALA in buffer, 5-ALA in phospholipid
