Death diclofenac

A number of anti-inflammatory drugs have now been tested for their therapeutic efficacy in AD. For example, the steroid prednisolone, which is lipophilic, has been administered to patients with AD for up to a year but the results were disappointing. The potent non-steroidal anti-inflammatories diclofenac and indomethacin have also been tested but shown to have minimal benefit with a high frequency of side effects. Perhaps these results are not surprising as it seems likely that the inhibition of COX will have little beneficial effect on the symptoms of AD once neuronal death has occurred, as seems likely in the clinical studies in which the patients were in the advanced... 

Recently, a case of vulture mortality was reported from the Indian subcontinent related to NS AID toxicity. Diclofenac is a widely available veterinary NS AID in the Indian subcontinent, used in domestic livestock. Vultures were exposed to the drug when they consumed carcasses of cattle that were treated with diclofenac shortly before death. Experimental studies of this drug in vultures showed marked nephrotoxicity. The gross observations were primarily deposits of urate on the surface of internal organs related to renal failure. Histopathological findings were acute necrosis of the proximal renal tubular epithelium with minimal inflammatory response and deposits of urate crystals (Oaks et al, 2004 Meteyer et al, 2005).
