Abstract: The present invention provides a transdermal drug delivery system which comprises: a therapeutically effective amount of a non-steroidal anti-inflammatory drug; at least one dermal penetration enhancer, which is a safe skin-tolerant ester sunscreen ester; and at least one volatile liquid. The invention also provides a method for administering at least one systemic or locally acting non-steroidal anti-inflammatory drug to an animal which comprises applying an effective amount of the non-steroidal anti-inflammatory drug in the form of the drug delivery system of the present invention.

Abstract: The invention relates to a method for treatment or prophylaxis of a disease or condition in an animal comprising administering to a mucosal membrane of said animal in need of such treatment a therapeutically effective amount of a drug delivery system comprising at least one physiologically active agent or prodrug thereof and at least one penetration enhancer selected from safe ester sunscreens.

Abstract: A topical cosmetic composition including: at least one water-soluble cosmetic agent; at least one oil-soluble cosmetic agent; and a dermal penetration enhancer, wherein topical application of the composition results in the delivery of the water-soluble and oil-soluble cosmetic agents into the stratum corneum as well as delivery of the oil-soluble cosmetic agent into the epidermis and dermis.

Abstract: The present invention provides a pharmaceutical composition for transdermal delivery comprising; one or more physiologically active agents; and a volatile pharmaceutically acceptable solvent; and wherein the physiological active agent forms a metastable deposit upon evaporation of the volatile solvent.

Abstract: A pharmaceutical composition for transdermal delivery comprising one or more physiologically active agents; one or more dermal penetration enhancers; and a volatile pharmaceutically acceptable carrier comprising a volatile solvent; and wherein the physiologically active agent and dermal penetration enhancer form an amorphous deposit upon evaporation of the volatile carrier, said amorphous deposit forming a reservoir within the stratum corneum; and (A) wherein the composition has a release rate profile of physiologically active agent so as to provide a ratio of the maximum concentration (Cmax) to the average concentration (Cavg) for the physiologically active agent over the dosage interval within the range of 1 to 10.
