Abstract

The invention relates to a gel plaster for treating myopia and its preparation method, composed of 2% -100% of extract of traditional Chinese medicine and 98% -0% of medicinal adjuvant, wherein the extracts of ginkgo leaf and chrysanthemum are extracted using alcohol extraction method; the water-based extract of bilberry fruit is extracted using water extraction and alcohol precipitation method. The traditional Chinese medicine plaster is prepared by mixing the molecule gel with the hydrogel and the water-soluble medicine enters into the skin through a water-based channel and the fat-soluble medicine enters into the skin by a fat-soluble channel, thus the production technique prevents the separation of medicine and matrix, at the same time a certain repulsion force of oil-based matrix to the water-based medicine and a certain repulsion force of water-based matrix to the oil-based medicine can promote the medicine absorption and the medicine efficacy is increased.

Description

technical field [0001] The invention relates to the newest molecular gel dosage form and hydrogel dosage form in the technical field of transdermal drug delivery preparations, a transdermal absorption gel patch for treating myopia with extracts of traditional Chinese medicines and a medicinal matrix and a preparation method thereof. Background technique [0002] Transdermal drug delivery system or percutaneous absorption patch refers to a type of preparation that is applied through the skin, and the drug is absorbed through the skin into the blood circulation of the whole body and reaches an effective blood concentration to achieve disease treatment or prevention. The characteristic of the transdermal absorption patch is that the transdermal drug delivery system can avoid the first-pass effect of the liver and the inactivation of the drug in the gastrointestinal tract, and the absorption of the drug is not affected by gastrointestinal factors, reducing the individual differen...
