Abstract

The invention discloses compound dexamethasone acetate nano-cream and a preparation method therefor. The cream comprises the following raw materials: dexamethasone acetate, camphor, menthol, a surfactant, a cosurfactant, an oil phase, a cream base material and water. The preparation method for the compound dexamethasone acetate nano-cream comprises the following steps: dissolving dexamethasone acetate in the oil phase, the surfactant and the cosurfactant, and uniformly mixing with the water to obtain nano (micro) emulsion; dispersing camphor, menthol and the nano-emulsion in the cream base and mixing uniformly to obtain the compound dexamethasone acetate nano-cream. The compound dexamethasone acetate nano-cream has the advantages of good smearing property and good transdermal effect.

Description
