Application of polyvinyl alcohol in modern medicine

With the mutual penetration of polymer material science and modern pharmacy, the application of polymer materials as drug controlled release carriers has become one of the most popular research directions”, among which polyvinyl alcohol is the most important polymer compound in this regard. Vinyl alcohol is usually prepared by alcoholysis of polyvinyl acetate in solvents such as methanol, ethanol or methyl acetate. The degree of alcoholysis is 98% – 100% for complete alcoholysis of polyvinyl alcohol. Polyvinyl alcohol is a good composition Film and gel materials are widely used in gels, transdermal preparations, film coating agents, and film preparations. They can also be used as the base of poultice. They are also ideal suspending agents and thickening agents. Mixtures and important slow-release and controlled-release matrix materials are non-toxic, tasteless, non-irritating to the skin, and not cause skin allergies. The good safety has attracted more and more attention.
