ReviewRenal adverse effects of nonsteroidal anti-inflammatory drugs.
NSAIDs depress prostaglandins synthesis through inhibition of COX-1 that is involved in maintaining cell integrity and COX-2 that, although presents particularly in the kidneys, is overexpressed in response to inflammation. Both the beneficial and side effects of NSAIDs are, therefore, through their inhibition of COX enzymes. Introduction of COX-2-selective inhibitors has improved the safety profile of the drugs with regard to their most common side effect which occurs at the gastrointestinal level but has not rendered them less cardio-nephrotoxic. ⋯ There is no known predictor for the nephrotoxicity. However, a relationship has been found between high plasma concentration and the renal adverse effect of NSAIDs. The usefulness of therapeutic drug monitoring in patients with risk factors needs to be explored.
