Adhesive film for hypertrophic scar repair and preparation method thereof

Abstract

The invention discloses a film for hyperplastic scar repair and a preparation method thereof. The film comprises a back lining layer, a viscous polymer layer and an isolation layer which are sequentially bonded, wherein the viscous polymer layer comprises a viscous polymer, a liposome permeation promoter and a scar removal active component and can keep good adhesiveness and cohesiveness in the case of moisture or sweat; meanwhile, with good hydrophilcity and lipophicity, the viscous polymer layer is more favorable for the medicine to penetrate through skin to promote medicine absorption, and a higher medicine-through-skin rate can be obtained. The film for hyperplastic scar repair, disclosed by the invention, takes effect quickly, the course of treatment is short, and the hyperplastic scar does not recur easily. The preparation method is simple, and the process cost is low.

Description

technical field

[0001] The invention relates to the technical field of scar repair, in particular to a patch for repairing hypertrophic scars and a preparation method thereof. Background technique

[0002] Hypertrophic scars mostly occur after the wounds and deep burns have healed. The pathological difference between hypertrophic scars and normal scars lies in the thickening of collagen fibers in the deep part of the scar, which is irregularly arranged, or wavy, or entangled into ropes. Hypertrophic scars have been constantly changing since they occurred. At the beginning, the fibrous hyperplasia of the scar is very fast and numerous. After the fibrous hyperplasia is too much, the blood vessels inside the scar are often compressed, making it gradually ischemic. Flushing and congestion, firm and tough, with burning pain and itching. The common incision scar after the incision is sutured belongs to this kind.

[0003] At present, the treatment of hypertrophic scars at home...
