Abstract

The invention provides a preparation method of mometasone furoate gelatin. The mometasone furoate gelatin is prepared from the following raw materials and auxiliary materials in proportion by weight of 1.0g of mometasone furoate, 8.0-10.0g of carbomer, 4.0-6.0g of triethanolamine, 50.0g of medical ethanol, 150.0g of glycerine, and 0-1.5g of ethylparaben, and purified water is added until the totalweight is 1000g, wherein the pH value of the mometasone furoate gelatin is 5.5-6.5, and the mass ratio of the triethanolamine to the carbomer is 0.40-0.55; single unknown impurities of the mometasonefuroate gelatin do not exceed 0.2%; the total impurities are not greater than 1.0%, and the mometasone furoate gelatin is stable under the high-temperature illumination condition. Besides, radix angelicae pubescentis, herba selaginellae, Chinese arborvitae twigs and leaves, hedyotis diffusa, a pharmaceutic adjuvant, azone and rice milk, which are added, have favorable treatment effect on treatment of foot fracture.

Description

technical field [0001] The present invention relates to the technical field of a kind of external preparation medicine, especially a kind of external use gel preparation medicine containing mometasone furoate, because this gel adopts the matrix combination of carbomer and triethanolamine, carbomer is used as the gel matrix , Triethanolamine as a pH regulator, glycerin as a humectant, has better moisturizing properties and penetration absorption effect, can effectively absorb through tissues without hindering the normal function of the skin, especially suitable for seborrheic skin diseases. Background technique [0002] Mometasone furoate is a synthetic topical glucocorticoid with strong anti-inflammatory effects and low inhibition of adrenal cortex function. Mometasone furoate gel has the effect of reducing inflammation and itching, suitable for skin diseases that are effective to glucocorticoids such as dermatitis (contact dermatitis, seborrheic dermatitis, atopic dermatiti...
