Hvis der er kompromitteret renal perfusion, kan administration af etoricoxib derfor forårsage reduktion i prostaglandindannelsen og sekundært i den renale blodgennemstrømning, og dermed forårsage nedsat nyrefunktion.
Therefore, under conditions of compromised renal perfusion, administration of etoricoxib may cause a reduction in prostaglandin formation and, secondarily, in renal blood flow, and thereby impair renal function.
