1 INTRODUCTION<br />

Polyvinyl pyrrolidone (PVP) is a polar <strong>and</strong> amorphous polymer that is completely<br />

soluble in water <strong>and</strong> some organic solvents, such as alcohols, chlorinated<br />

hydrocarbons, dimethylformamide, <strong>and</strong> N-methylpyrrolidone. It is an important<br />

polymer in the pharmaceutical, personal care, cosmetic, agriculture, beverage, <strong>and</strong><br />

other industries.<br />

PVP is a physiologically inert <strong>and</strong> biologically compatible polymer. PVP is<br />

known to reduce significantly the toxicity <strong>and</strong> irritant effects <strong>of</strong> many medications.<br />

PVP can form complexes with a variety <strong>of</strong> substances. For example, the PVP–<br />

iodine complex in the form <strong>of</strong> povidone or Betadine aqueous solution is the most<br />

widely used antiseptic in hospitals. It significantly reduces the toxicity <strong>and</strong> staining<br />
