ANTIINFLAMMATORY AND ANALGESIC PREPARATION FOR EXTERNAL USE

摘要

It is intended to provide an antiinflammatory and analgesic preparation for external use whereby side effects of a nonsteroidal antiinflammatory and analgesic drug on the skin can be regulated, the nonsteroidal antiinflammatory and analgesic drug can be prevented from degeneration with time due to a dibenzoylmethane derivative contained as an UV absorbent therein, the dibenzoylmethane derivative can be prevented from crystallization and sedimentation due to an oily phase component contained therein, and the inherent effects of the nonsteroidal anti-inflammatory and analgesic drug can be fully exerted without showing skin irritation caused by the oily phase component, an emulsifier and a thickener. The above problem can be solved by providing an antiinflammatory and analgesic preparation for external use which comprises a base for external use containing an oily phase component, a nonsteroidal antiinflammatory and analgesic drug and a dibenzoylmethane derivative and in which the total amount of fatty acid esters in the oily phase component is at least thrice as much as the content of the dibenzoylmethane derivative.
