Acunivive 90 Injection System and Renal dysfunction

The use of ketorolac is contraindicated in patients with advanced renal impairment or increased risk for renal failure due to volume depletion. Ketorolac is a potent nonsteroidal anti-inflammatory drug (NSAID). The use of NSAIDs may be associated with renal toxicities, including elevations in serum creatinine and BUN, tubular necrosis, glomerulitis, renal papillary necrosis, acute interstitial nephritis, nephrotic syndrome, and renal failure. In patients with prerenal conditions whose renal perfusion may be dependent on the function of renal prostaglandins, NSAIDs may precipitate overt renal decompensation via a dose-related inhibition of prostaglandin synthesis. Patients at greatest risk for this reaction include geriatric patients and those with impaired renal function, heart failure, liver dysfunction, or substantial volume and/or sodium depletion (e.g., due to diuretics). Therapy with ketorolac should be administered cautiously in such patients, and hypovolemia and hyponatremia should be corrected prior to initiating treatment. Clinical monitoring of renal function is recommended during therapy. If renal function declines or renal failure occurs, prompt discontinuation of ketorolac therapy will usually lead to recovery to the pretreatment state. Since ketorolac and its metabolites are eliminated by the kidney, a reduction to half the normal dosage with a maximum of 60 mg/day is recommended in patients with moderately impaired renal function to avoid drug accumulation.
