Introduction of medicinal polymer materials
Medicinal polymer materials are a kind of drug sustained-release technology, which is covered by medical polymer materials on the surface of the drug. Of course, the drug is not a block, but it is very small. Due to the protection of polymer materials, the drug will not be absorbed by the body in a short time, but will flow to a specific area with the blood. After reaching the drug, the polymer material on the surface of the drug has dissolved in the blood and eventually discharged with the body fluid. And drugs can be targeted to treat patients.
