Problems solved by technology

[0003] But the absorption rate of existing compound dexamethasone acetate emulsifiable paste is low, is easy to cause the waste of crude drug, simultaneously, because compound recipe dexamethasone acetate emulsifiable paste is formed by water phase, oily phase and emulsifying agent, emulsifiable paste is placed for a long time Afterwards, it is easy to be unstable, and it is easy to cause the cream to lose its effectiveness due to oil-water separation. In addition, the main ingredient is not evenly distributed in the cream, which also affects the stability of the drug effect.

Abstract

The invention provides compound dexamethasone acetate cream and a preparation method thereof and relates to the technical field of drug preparations. The compound dexamethasone acetate cream disclosedby the invention mainly comprises dexamethasone acetate, a water-based ingredient, an oil-based ingredient, dimethyl sulfoxide, 2,6-ditertbutyl-4 methylphenol, camphor, menthol and water. The compound dexamethasone acetate cream prepared from the previous components does not have any irritation or allergy to human skin, has the advantages of being moderate in viscosity and easy to apply, is excellent in moisturizing effect and is favorable for drug utilization. Moreover, the stability is high, and the main drug ingredient has uniform distribution and stable quality in the cream.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a compound dexamethasone acetate cream and a preparation method thereof. Background technique [0002] Compound dexamethasone acetate cream is a skin medicine for external use, which has significant curative effect on localized pruritus, neurodermatitis, contact dermatitis, seborrheic dermatitis and chronic eczema. [0003] But the absorption rate of existing compound dexamethasone acetate emulsifiable paste is low, is easy to cause the waste of crude drug, simultaneously, because compound recipe dexamethasone acetate emulsifiable paste is formed by water phase, oily phase and emulsifying agent, emulsifiable paste is placed for a long time Afterwards, it is easy to be unstable, and it is easy to make the cream lose its effect due to oil-water separation. In addition, the uneven distribution of the main ingredients in the cream also affects the stability of the...
