[0025]

[0026] Preparation:

[0027] 1) Preparation of the water phase: heat the purified water to 70°C to 75°C, add buffered p-phosphate-sodium phosphate buffer pair (pH=5), dextrin, nonylphenol polyoxyethylene ether and methylparaben and stir to mix Evenly, keep warm for later use;

[0028] 2) Preparation of the oil phase: heating the oil base, including light liquid paraffin, cetostearyl alcohol, white petrolatum, and beeswax to melt to obtain the oil phase material, and keeping it warm at 70°C to 75°C for later use;

[0029] 3) Preparation of main drug dispersion: disperse desonide in glycerin to obtain main drug dispersion suspension;

[0030] 4) Total mixing: the oil phase material and the water phase material are mixed evenly, and the dispersion suspension of the main ingredient is added;

[0031] 5) Cooling: Mix evenly and cool to room temperature to obtain desonide cream.

Abstract

The invention provides desonide cream and a preparation method thereof. The desonide cream comprises desonide serving as an active component, a polyoxyethylene ether emulsifier, a buffer pair, dextrin, glycerol, an antibacterial agent and an oily matrix. The buffer pair is dissolved in water to achieve a pH value of 4.5-5.5. The desonide cream has no obvious change in character after being exposed to high temperature, high humidity, low temperature, freeze thawing and illumination, has no obvious increase in maximum single impurity and total impurity, and can adapt to various environmental conditions encountered in storage and transportation. Meanwhile, the desonide cream disclosed by the invention is simple in preparation process and easy for industrial production.

Description

technical field [0001] The invention belongs to the technical field of medicine, and in particular relates to a desonide cream and a preparation method thereof. Background technique [0002] Topical glucocorticoids have the advantages of high curative effect, quick effect, good compliance, and easy acceptance by patients. They are one of the drugs commonly prescribed by dermatologists. Desonide is a weak hormone with anti-inflammatory, anti-allergic, anti-itching and reducing exudation effects. It can reduce the response of tissue inflammation and eliminate congestion and edema caused by local inflammation. It has good safety and effectiveness. [0003] At present, the approved dosage forms of desonide preparations are all external preparations, especially cream dosage forms, which are widely used. Cream preparations are usually stored in an airtight, cool place. The stability of cream formulations is also worse than other solid formulations. Therefore, cream preparations...
