Abstract
The invention relates to compound emulsifiable paste for treating acne and a preparation method thereof, in particular to a medicament for treating acne and a preparation method thereof. The compound emulsifiable paste solves the problems of long treatment course and skin oxidation, dim skin and formation of color spots in the healing process in the conventional medicament for treating the acne. The compound emulsifiable paste is prepared from clindamycin hydrochloride, metronidazole, vitamin A, vitamin C, an emulsifying agent, stearic acid, albolene, glycerol monostearate, lanolinum, glycerol and purifying water. The preparation method comprises the following steps of: adding the vitamin A into uniform solution prepared from the stearic acid, the albolene, the glycerol monostearate and the lanolinum to obtain an oil phase; dissolving the glycerol and the emulsifying agent into the purifying water, adding the clindamycin hydrochloride, the metronidazole and the vitamin C, and stirring uniformly to obtain a aqueous phase; and adding the oil phase into the aqueous phase, stirring, homogenizing and standing the mixture to obtain the compound emulsifiable paste for treating the acne. The treatment period of the compound emulsifiable paste is between 14 and 24 days, skin is bright and clean after healing, and the compound emulsifiable paste can treat the acne, seborrheic dermatitis, acne rosacea and folliculitis.
Description
technical field [0001] The invention relates to a medicine for treating acne and a preparation method thereof. Background technique [0002] Acne is a chronic inflammation of the pilosebaceous glands caused by the combined action of multiple factors. It is generally caused by the accumulation of sebum in the hair follicle. The accumulation of sebum in the hair follicle leads to the proliferation of Propionibacterium acnes in the hair follicle. The enzyme produced by P. acnes can decompose Free fatty acids are produced from sebum, which stimulates hair follicles and causes inflammation. At present, there are many methods for treating acne clinically. Among them, liniment and ointment made by combining clindamycin and metronidazole, because clindamycin and metronidazole only play a bactericidal and bacteriostatic effect , for the skin ulcer formed after acne, it can only be healed by the skin itself. The treatment course is 60-90 days, the treatment course is long, and at the...
