Emulsions and creams containing ibuprofen effective for topical administration of the ibuprofen are provided without the presence of conventional O/W emulsifying agent. The emulsions and creams are formed by using the ibuprofen, in the form of its salt, as the O/W emulsifying agent. A minor amount of a W/O emulsifying agent may be included in the composition. Percutaneous delivery of ibuprofen is improved by using a skin penetration enhancing compound, such as 2-n-nonyl-1,3-dioxolane or decanaldimethyl acetal, as the oily phase of the emulsion.
含有布洛芬的乳液和膏霜可有效用于布洛芬的局部用药,而无需使用传统的水包油型乳化剂。这些乳液和膏霜是以布洛芬盐的形式作为水包油型乳化剂形成的。组合物中可加入少量的水包油型乳化剂。使用皮肤渗透增强化合物,如 2-壬基-1,3-二氧戊环或癸醛二甲基缩醛,作为乳液的油相,可改善布洛芬的经皮给药。
