Crospovidone (cross linked polyvinyl N-pyrrolidone, or PVP) is a common, FDA-approved inactive ingredient used in the pharmaceutical industry. Crospovidone is often combined with active ingredients in medications and dietary supplements to allow absorption of the active drug. It is considered a synthetic povidone analog. Chemically, crospovidone is an inert and insoluble white to light yellow free-flowing powder. It has hygroscopic, or water-attracting properties with excellent swelling characteristics. It is this swelling characteristic that makes it useful as a disintegrant in pharmaceutical dosage forms.
