Abstract

The invention relates to the technical fields of medicinal preparations and preparation methods thereof and particularly discloses a formula of povidone iodine ointment of full water-soluble matrix and a preparation method thereof. The povidone iodine ointment consists of the following components in percentage by weight: 10 percent of povidone iodine, 0.1 to 0.5 percent of potassium iodate, 20 to 31 percent of polyethylene glycol-400, 20 to 30 percent of polyethylene glycol-4000, 5 to 15 percent of xylitol or sorbitol serving as a matrix protecting agent, 15 to 20 percent of glycerol, 0.5 to 2.0 percent of sodium dodecyl sulfate, and 7.5 to 15 percent of purified water. By using unique protective methods and means, the technical problem of low stability in preparation and storage processes of the ointment after the povidone iodine and the water-soluble polyethylene glycol matrix are mixed is solved, the povidone iodine ointment with good performance advantages is prepared, the manufacturing time is greatly shortened, the working efficiency is improved, and the povidone iodine ointment is suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of pharmaceutical preparations and preparation methods thereof, in particular to a prescription of povidone-iodine ointment with a fully water-soluble matrix and a preparation method thereof. Background technique [0002] Povidone-iodine is a broad-spectrum and highly effective disinfectant and antiseptic, which can kill a variety of bacteria, spores, viruses, fungi, etc. Its mechanism of action is that after povidone-iodine contacts the wound or affected area, it can depolymerize and release iodine to play a bactericidal effect. Povidone-iodine is less irritating to tissues and is very suitable for the treatment of skin and mucous membrane infections. Clinically, it is often used in the treatment of burns, scalds, trauma infections, candida vulvovaginosis, bacterial vaginosis and mixed infectious vaginitis, and can also be used to treat hemorrhoids. "Chinese Pharmacopoeia" 2010 Edition (Part II) contains ...
