Abstract
This study was aimed to investigate the influence of diabetes or arthritis on the enantioselective metabolism and kinetic disposition of fenoprofen in rats with streptozotocin-induced diabetes or Mycobacteriumtuberculosis adjuvant-induced arthritis. Animals received i.v. 10 mg/kg racemic fenoprofen and blood samples were collected up to 24 h thereafter, with 5 animals studied at each time point. Plasma concentrations of the fenoprofen enantiomers were determined by HPLC. Diabetic and arthritic animals showed significant differences when compared with respective controls for the following pharmacokinetic variables of the (+)-(S)-fenoprofen eutomer: area under the plasma concentration time curve, total clearance and volume of distribution. The results indicate that experimental diabetes and adjuvant-induced arthritis influence the fenoprofen enantioselective metabolism.
