Ketorolac Use in Renal Impairment
Ketorolac should be avoided in patients with advanced renal impairment because ketorolac is contraindicated in this setting. [1] Ketorolac should also be avoided in patients at risk for renal failure due to volume depletion. [1] Ketorolac requires caution in patients with impaired renal function and should be closely followed due to reduced renal clearance and reported acute kidney injury syndromes. [1], [2]
Contraindications With Elevated Serum Creatinine or Advanced Renal Impairment
Ketorolac is contraindicated in patients with serum creatinine concentrations indicating advanced renal impairment. [2] Ketorolac is contraindicated in patients with advanced renal impairment. [1] Ketorolac is contraindicated in patients at risk for renal failure due to volume depletion. [1]
Medication Selection Algorithm
Ketorolac should not be used when advanced renal impairment is present. [1], [2] Ketorolac should not be used when volume depletion is present due to increased risk of renal failure. [1] If an NSAID is being considered in the setting of chronic kidney disease, use of potential nephrotoxins should be minimized when possible. [3]
Important Clarifications on Renal Function Assessment
Ketorolac clearance is reduced in patients with reduced creatinine clearance, which decreases ketorolac clearance. [1], [2] Ketorolac is primarily eliminated by the kidneys, so renal dysfunction increases exposure risk. [1], [2]
Dosing Nuances in Renally Impaired Populations
For patients ≥65 years of age who are renally impaired, ketorolac injection dosing is reduced to 15 mg IV/IM every 6 hours with a maximum daily dose of 60 mg. [1] For patients ≥65 years of age who are renally impaired and weigh <50 kg, the same reduced regimen applies. [1]
Treatment Initiation Thresholds
Ketorolac initiation should not occur when serum creatinine indicates advanced renal impairment, as this is a labeled contraindication. [2] Ketorolac should not be initiated in patients at risk for renal failure from volume depletion. [1]
Common Pitfalls to Avoid
Ketorolac should be avoided in advanced renal impairment because it is contraindicated and because reduced renal clearance increases drug exposure. [1], [2] Ketorolac should not be administered during states of hypovolemia or volume depletion, since the label identifies risk for renal failure in this setting. [1]
Renal Safety Goal of Therapy
Non-nephrotoxic alternatives should be prioritized when possible in chronic kidney disease to reduce exposure to nephrotoxic medications, including NSAIDs. [3]
Bottom-Line Clinical Answer
Ketorolac should be avoided (contraindicated) in patients with advanced renal impairment or when serum creatinine indicates advanced renal impairment. [1], [2] Ketorolac should also be avoided when at risk for renal failure due to volume depletion. [1] Ketorolac should be used with caution and close monitoring only when renal impairment does not meet the labeled contraindication criteria. [1], [2]
