Kollisolv® PYR

Solvent for injectables and oral formulations for animal health.

It has also been suggested for use in human pharmaceutical formulations as solvent in parenteral, oral, and topical applications. In topical applications, Kollisolv® PYR appears to be effective penetration enhancer. Pyrrolidone has also been investigated for their application in controlled-release depot formulations. Kollisolv® PYR shows strong antimicrobial effectiveness against gram-positive and gram-negative bacteria and moulds.
