Abstract

The invention discloses a resin type matrix and its preparation method wherein the resin type matrix comprises medical hot melt pressure-sensitive glue, rosin, zinc oxide, crystallite wax, ortho-phthalic acid dimethyl esters, and sorbic acid.

Description

Technical field [0001] The invention relates to a medicine matrix with a special physical form and a preparation method thereof, in particular to a resin matrix of an ointment patch and a preparation method thereof. Background technique [0002] There are mainly three types of existing ointment patch bases, namely black plaster, rubber gel and cataplasm base. The traditional black plaster of traditional Chinese medicine is made from traditional Chinese medicinal materials, sesame oil is extracted from medicinal oil at high temperature and lead Dan is boiled. Its disadvantage is that the process is complicated, the product quality is difficult to control, and the active ingredients of traditional Chinese medicine are easily destroyed during high temperature extraction. Due to the lead-containing products in the black plaster matrix, there is a risk of lead poisoning in patients using black plasters. In addition, the black plaster must be preheated t...
