The objective of the present invention is to provide a preparation technique with which cloudiness and the formation of a precipitate can be suppressed and excellent appearance characteristics can be provided even when diclofenac and a tocopherol and/or derivative thereof are included in a pharmaceutical composition for external use that includes water. Provided is a pharmaceutical composition for external use that includes diclofenac and/or a salt thereof, a tocopherol and/or derivative thereof, and water, wherein by mixing in menthol, cloudiness and the formation of a precipitate due to diclofenac and/or a salt thereof and a tocopherol and/or derivative thereof can be suppressed, and excellent appearance characteristics can be provided.本發明之目的，係提供一種於含有水的外用醫藥組成物中，含有待克菲那(diclofenac)與生育醇及/或其衍生物，同時抑制白濁及析出物之生成，且可使其具備優異外觀性狀之製劑技術。解決方法係於含有待克菲那及/或其鹽、生育醇及/或其衍生物以及水之外用醫藥組成物中，藉由摻合薄荷醇，可抑制起因於待克菲那及/或其鹽與生育醇及/或其衍生物之白濁及析出物之生成，且使其具備優異外觀性狀。
