Problems solved by technology

However, these indicators are not enough to reflect the quality of the gel plaster. The gel plaster that meets the requirements of the Pharmacopoeia still has quality problems such as peeling off, loss of viscosity, and ointment leakage.
Moreover, for the adhesion that is crucial in the quality index of gel plaster, although the Pharmacopoeia stipulates the determination methods and e

Abstract

The invention relates to a medicament matrix composition and a preparation method. PVPK90 (polyvinylpyrrolidone K90), PAAS700 (sodium polyacrylate 700), dihydroxyaluminium aminoacetate, tartaric acid, glycerol and purified water are taken as raw materials and are mixed, stirred and formed into the medicament matrix composition. The matrix has the characteristics of primary viscous force, keeping viscous force, peel strength, adhesive force balancing, and the like; the matrix is mixed with the raw material drugs; the materials are uniformly stirred and mixed, coated, dried, checked and packaged, thereby acquiring the gel plaster used for treating the related diseases.

Description

1. Technical field [0001] The present invention relates to a kind of medicine matrix composition and its preparation method and application, in particular to a kind of gel plaster matrix composition, its preparation method and its application for preparing gel plaster. 2. Background technology [0002] Gel plaster refers to the plaster made by mixing the raw drug with a suitable hydrophilic matrix and coating it on the backing material. Commonly used bases include sodium polyacrylate, sodium carboxymethyl cellulose, gelatin, glycerin and micronized silica gel etc. my country carried out the research on the gel plaster (formerly known as the Babu ointment) in the 1980s, and by the early 1990s, the traditional Chinese medicine Babu ointment began to be produced on a large scale. So far, the domestic marketed gel plaster drugs include Shanghai Leiyunshang Pharmaceutical Co., Ltd.'s joint pain relieving babu ointment, compound Bauhinia Xiaoshang babu ointment and Chanwu gel oin...
