Role of Plasma Proteins in Pharmacokinetics of Micafungin, an Antifungal Antibiotic, in Analbuminemic Rats

Abstract

There were no significant differences in the pharmacokinetics of micafungin and expression of hepatic multidrug resistance-associated protein 2 (ABCC2/Mrp2) between analbuminemic and Sprague-Dawley rats. Micafungin bound strongly to high-density lipoprotein (HDL) and moderately to gamma globulin. These results suggest that HDL and gamma globulin contribute to the pharmacokinetics of micafungin.
