Non-steroidal Anti-inflammatory Drugs: Clinical Implications, Renal Impairment Risks, and AKI.

Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most common class of drugs utilized for a variety of disorders, including headaches, pain states, fever, and other common conditions. In recent years, a link between NSAIDs and adverse effects has been identified, including renal, heart, and liver disease, bleeding, and increased mortality. NSAID-mediated renal disease is associated with interference with the cyclooxygenase enzyme. Literature evaluating NSAID renal effects has indicated that a number of factors are associated with acute and chronic kidney injury (AKI). Early diagnosis can identify changes in renal function and allow for cessation of NSAID use, limiting the risk for long-term chronic renal disease and in some cases reversal of renal injury. Alternative medications should be considered in those patients identified with morbidity linked to NSAID use. Nephrotoxicity is increased in the elderly population and in hypovolemia, high dose exposure, use of vasoconstrictors such as calcineurin inhibitors, and use of renin-angiotensin-aldosterone system (RAAS) inhibitors or diuretics. Careful risk/benefit considerations from healthcare professionals can limit the incidence and degree of morbidity and mortality, including in NSAID-mediated renal disease. Selective NSAID cyclooxygenase-2 inhibitors also possess risks and therefore clinicians should always recommend short-term courses of this class of drugs versus long-term dosing because of the risk of morbidity and mortality. Given that these drugs are available over the counter as well by prescribing, clinicians must communicate the risks and benefits of NSAIDs and provide sound recommendations to their patients regarding use short and long term.
