Abstract

The invention relates to the technical field of a medicinal preparation, and relates to a preparation method of a benzoyl peroxide gel. The prescription ingredient ratio of the benzoyl peroxide gel ischaracterized in that a main drug comprises 5% of benzoyl peroxide (based on pure basis), a gel matrix is 0.60% to 1.0% of carbomer 980, a wetting agent is 3% to 5% of propylene glycol, a surfactantis 0.1% to 0.3% of poloxamer 188, a chelating agent is 0.1% of disodium edetate, a surfactant is 0.05% of docusate sodium, a suspending agent is 0.02% to 0.05% of colloidal silica, an adsorbent is 1.5% to 2.5% of an acrylate copolymer (polytrap 6603), a humectants is 3 % to 5% of glycerin, a pH regulator is 0.14% of sodium hydroxide and a solvent, and purified water is supplied to 100%. The methodis characterized in that a carcinogenic solvent (benzene) is used in the production process of Carbomer 940, and a part of benzene remains in the commercial Carbomer 940, in the technical scheme, thecarbomer 980 is used instead of carbomer 940, and carbomer 980 does not contain benzene, so the product safety is improved.

Description

Technical field [0001] The invention relates to the technical field of pharmaceutical preparations, in particular to a preparation method of benzoyl peroxide gel. Background technique [0002] The original research company of benzoyl peroxide gel was Laboratoires Galderma, which was approved to be marketed in France on March 19, 1986. The trade name is CUTACNYL, and the specifications are 5% and 10%. In July of the same year, it was listed with 2.5% specifications. Currently, there is no unilateral listing in the United States, Japan approved the listing in 2014, and China has original imported varieties. [0003] In December 2014, Japan approved Maruho Co., Ltd's benzoyl peroxide gel to be marketed, with specifications of 2.5%, 15g and 30g. This is the first time that benzoyl peroxide has been used to treat acne vulgaris in Japan. However, carbomer 940 in most benzoyl peroxide prescriptions on the market currently uses carcinogenic solvent (benzene) in the production process, so ...
