Using Urinary Biomarkers to Evaluate Renal Effects of a Cox-2 NSAID in Volunteers

Abstract

We explored urinary biomarkers as an alternative for measuring the effect of an experimental COX-2 inhibitor on renal function in volunteers. Thirty male volunteers between the ages of 20–40 were enrolled and a COX-2 NSAID was given in a blinded design. The acute administration of an oral COX-2 NSAID resulted in a consistent increase in the urinary enzyme AAP at 2 hours. At 24 hours after COX-2 NSAID administration values for most of the urinary biomarkers had returned to baseline suggesting that such effects are transient and without clinical significance in situations of acute administration.
