Problems solved by technology

Compared with the two, the onset of oral administration is slow, but the increase in pain is large and lasting
[0012] Since the early 1980s, a large number of Chinese medicine cataplasms have been studied in China. There are a large number of related patents and literature reports, but there are few products on the market, especially the traditional Chinese medicine cataplasm In terms of new product development and market share, the agent is still far from forming a scale. Compared with foreign products, the marketed products are seriously behind. There are mainly the following two problems: 1. Poor appearance and poor application comfort (too sticky or poor adhesion) 2. Low formability (it is easy to become thin when the temperature is high or high humidity, the matrix is ​​easy to deform and flow or the skin has residue); 3. The active ingredients in the traditional Chinese medicine compound are mutually restricted and balanced, and they work together to form It is not possible to ensure that each active ingredient has transdermal permeability after cataplasm
The root causes of these problems mainly lie in: the vast majority of domestic products are non-cross-linked products, and the paste strength (formability) is poor; Large differences in properties; and unreasonable prescription design, etc.
