MONITOR: Nonsteroidal anti-inflammatory drugs (NSAIDs) may attenuate the antihypertensive effects of ACE inhibitors. The proposed mechanism is NSAID-induced inhibition of renal prostaglandin synthesis, which results in unopposed pressor activity producing hypertension. In addition, NSAIDs can cause fluid retention, which also affects blood pressure. Some NSAIDs may also alter the pharmacokinetics of certain ACE inhibitors. For example, oxaprozin has been shown to reduce the systemic exposure (AUC) of enalapril and its active metabolite, enalaprilat.
MONITOR: Concomitant use of NSAIDs and ACE inhibitors may increase the risk of renal impairment, particularly in volume-depleted patients. Chronic use of NSAIDs alone 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. Additionally, in patients with prerenal conditions whose renal perfusion may be dependent on the function of prostaglandins, NSAIDs may precipitate overt renal decompensation via a dose-related inhibition of prostaglandin synthesis. ACE inhibitors can further worsen renal function by blocking the effect of angiotensin II-mediated efferent arteriolar vasoconstriction, thereby decreasing glomerular filtration.
MANAGEMENT: Patients receiving ACE inhibitors who require prolonged (greater than 1 week) concomitant therapy with an NSAID should have blood pressure monitored more closely following initiation, discontinuation, or change of dosage of the NSAID. Renal function should also be evaluated periodically during prolonged coadministration. The interaction is not expected to occur with low doses (e.g., low-dose aspirin) or intermittent short-term administration of NSAIDs.
