Abstract

Transdermally absorbable water-containing preparations of therapeutically active arylpropionic acid derivatives comprises 1 to 15% by weight of such active ingredient, from 10 to 40% by weight of polyoxyethylene polyoxypropylene copolymers, from 10 to 50% by weight of one or more physiologically acceptable organic solvents, optionally up to 1% by weight of preservatives, colorants and/or perfumes, and at least 10% by weight of water. From polyoxyethylene polyoxypropylene copolymers having a relative molecular weight of more than 6,000 there may also be prepared gels, if certain ratios of amounts are chosen.
