Abstract
Abstract A pharmaceutical composition for topical treatment of cutaneous disorders or disruptions characterized by skin inflammation or hyperproliferative epidermal activity comprises the combination of a topically active anti-inflammatory corticosteroid and a non-steroidal anti-inflammatory agent which is an inhibitor of prostaglandin synthetase selected from the group consisting of the hydratropic acid derivatives; acetylsalicylic acid; the pyrazolon derivatives; the fenamic acid derivatives; the aroyl-substituted pyrroles and the substituted arylacetohydroxamic acids in a pharmaceutically acceptable topical vehicle. Treatment of above cutaneous disorders may also be effected by concurrent therapy using separate applications of corticosteroid and non-steroid.
