aspirin kanamycin

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.

Applies to: Goody's Headache Powders (acetaminophen / aspirin / caffeine) and Goody's Headache Powders (acetaminophen / aspirin / caffeine)

One study has reported that coadministration of caffeine and aspirin lead to a 25% increase in the rate of appearance and 17% increase in maximum concentration of salicylate in the plasma. A significantly higher area under the plasma concentration time curve of salicylate was also reported when both drugs were administered together. The exact mechanism of this interaction has not been specified. Physicians and patients should be aware that coadministration of aspirin and caffeine may lead to higher salicylate levels faster.

GENERALLY AVOID: Chronic, excessive consumption of alcohol may increase the risk of acetaminophen-induced hepatotoxicity, which has included rare cases of fatal hepatitis and frank hepatic failure requiring liver transplantation. The proposed mechanism is induction of hepatic microsomal enzymes during chronic alcohol use, which may result in accelerated metabolism of acetaminophen and increased production of potentially hepatotoxic metabolites.

MANAGEMENT: In general, chronic alcoholics should avoid regular or excessive use of acetaminophen. Alternative analgesic/antipyretic therapy may be appropriate in patients who consume three or more alcoholic drinks per day. However, if acetaminophen is used, these patients should be cautioned not to exceed the recommended dosage (maximum 4 g/day in adults and children 12 years of age or older).

GENERALLY AVOID: The concurrent use of aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) and ethanol may lead to gastrointestinal (GI) blood loss. The mechanism may be due to a combined local effect as well as inhibition of prostaglandins leading to decreased integrity of the GI lining.

MANAGEMENT: Patients should be counseled on this potential interaction and advised to refrain from alcohol consumption while taking aspirin or NSAIDs.

The effect of grapefruit juice on the pharmacologic activity of caffeine is controversial. One report suggests that grapefruit juice increases the effect of caffeine. The proposed mechanism is inhibition of cytochrome P-450 metabolism of caffeine. However, a well-conducted pharmacokinetic/pharmacodynamic study did not demonstrate this effect. The clinical significance of this potential interaction is unknown.

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.
