Dressing for promoting wound healing of burns and scalds and preparation method thereof

Abstract

The invention discloses a dressing for promoting wound healing of burns and scalds. The composition is prepared from the following raw materials in parts by weight: 17-23 parts of polyvinylpyrrolidone, 2-8 parts of caffeic acid-4-3-hydroxypropyl morpholine ester, 5-10 parts of glutathione, 0.5-0.8 part of chlorella extract, 0.3-0.5 part of L-lactic acid, 0.5-1.2 parts of asiaticoside, 0.4-0.8 partof inositol nicotinate, 0.5-0.7 part of hydroxyethyl urea, 0.35-0.7 part of laurocapram, 1.5-3 parts of a film-forming agent, 2-5 parts of borneol, 1-4 parts of hydrogenated lecithin and 40-50 partsof purified water. According to the dressing provided by the invention, polyvinylpyrrolidone is used as a matrix, and caffeic acid-4-3-hydroxypropyl morpholine ester and glutathione are added to promote rapid healing of burn and scald wounds. The chlorella extract and the L-lactic acid can regulate and control synthesis of collagen at the wound surface, the inositol nicotinate can relieve edema atthe burn and scald wound surface, and the asiaticoside and the hydroxyethyl urea can prevent the dressing and the wound surface from adhering to damage new tissues. The invention also provides a preparation method of the dressing for promoting wound healing of burns and scalds, the preparation process is simple and easy to operate, and commercial production and application are facilitated.
