Usage PVP have excellent physical inert, and will not participate in the body's metabolism, and have excellent biocompatibility, to skin and mucous membrane, do not form any stimulus such as eye. From a biological standpoint, the molecular structure characteristics PVP with simple protein similar to the kind of structure model and even its water-soluble for some small molecules and cooperating ability can be certain proteins precipitation agent of acetic acid and ammonium sulfate, trimethoxysilane tannins and phenolic place precipitation etc character also and protein phase to dissolve. That makes PVP is widely used as pharmaceuticals trims. As follows: (1) the concrete application of the binder (2) as preparations precipitation agent (3) of the help solvent as injection or crystal formation stop agent (4) coating or into pellicle (5) HuanShiJi drugs delay agent, controlled release of drugs can be prolonged duration 6 artificially vitreous and cornea surgical BaoZaDai behaved. In addition, PVP is still can be used as colorants and X-ray contrast agents; Can be used in tablet, granules, agent and so on many kinds of forms drug, with detoxification, hemostatic, improve dissolved concentration, prevent peritoneal adhesion, promote XieChen functions.
