MONITOR: The nephrotoxic effect of aminoglycosides may be potentiated by nonsteroidal anti-inflammatory drugs (NSAIDs), particularly if the latter had been given in high dosages for prolonged periods. Four children with cystic fibrosis who had been receiving chronic ibuprofen developed acute renal insufficiency shortly after initiation of IV aminoglycoside therapy for pulmonary exacerbations. An adolescent with CF who received intermittent, standard-dose ibuprofen during treatment with IV gentamicin also developed renal failure in addition to severe vestibular toxicity. Animal models suggest that renal prostaglandins may play a role in maintaining normal renal blood flow and glomerular filtration rate during the development of aminoglycoside nephrotoxicity, thus inhibition of their production by NSAIDs may worsen the renal damage.

MANAGEMENT: Whenever feasible, NSAID use should preferably be discontinued prior to initiating IV aminoglycoside therapy. If concomitant administration is necessary, hydration status as well as renal and vestibular functions should be closely monitored.

MONITOR: In premature infants, NSAIDs may increase the plasma concentrations of aminoglycosides. The proposed mechanism is decreased aminoglycoside clearance due to NSAID reduction of glomerular filtration rate, which is already low in premature infants. In a study of 20 preterm infants who had been given at least three days of amikacin or gentamicin therapy, mean peak plasma concentration increased by 17% and 33%, and mean trough concentration increased by 29% and 48%, respectively, on day 1 following administration of IV indomethacin for patent ductus arteriosus. Serum creatinine increased by 17%, while urine output and serum sodium decreased. Six patients developed hyponatremia.

MANAGEMENT: It may be advisable to consider reducing the dosage of aminoglycoside prior to initiation of NSAID therapy in infants. During coadministration, plasma antibiotic concentrations and renal function should be closely monitored, and the antibiotic dosage further adjusted as necessary.

MONITOR: Many psychotherapeutic and CNS-active agents (e.g., anxiolytics, sedatives, hypnotics, antidepressants, antipsychotics, opioids, alcohol, muscle relaxants) exhibit hypotensive effects, especially during initiation of therapy and dose escalation. Coadministration with antihypertensives and other hypotensive agents, in particular vasodilators and alpha-blockers, may result in additive effects on blood pressure and orthostasis.

MANAGEMENT: Caution and close monitoring for development of hypotension is advised during coadministration of these agents. Some authorities recommend avoiding alcohol in patients receiving vasodilating antihypertensive drugs. Patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their physician if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.

MONITOR: Calcium-containing products may decrease the effectiveness of calcium channel blockers by saturating calcium channels with calcium. Calcium chloride has been used to manage acute severe verapamil toxicity.

MANAGEMENT: Management consists of monitoring the effectiveness of calcium channel blocker therapy during coadministration with calcium products.

The consumption of grapefruit juice may slightly increase plasma concentrations of amlodipine. The mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruits. Data have been conflicting and the clinical significance is unknown. Monitoring for calcium channel blocker adverse effects (e.g., headache, hypotension, syncope, tachycardia, edema) is recommended.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
