PRANOPROFEN-CONTAINING FORMULATION

摘要

PROBLEM TO BE SOLVED: To inhibit the photodecomosition of pranoprofen.

SOLUTION: The pranoprofen-containing formulation comprises pranoprofen or a salt thereof; a nonionic surfactant; and at least one member selected from the group consisting of pyridoxine or a salt thereof; pantothenol; calcium pantothenate; sodium pantothenate; aminoethylsulfonic acid; sodium chondroitin sulfate; epsilon-aminocaproic acid; aspartic acid or a salt thereof; and allantoin. In this formulation, the pranoprofen is greatly stabilized against light. The formulation can keep its appearance better over a long term because it does not suffer from the formation of precipitates and insolubles and can be kept clear.
