Interactions between your drugs

Moderate

cefoperazone entecavir

Applies to: cefoperazone and entecavir

MONITOR: Coadministration of entecavir with another drug that is also eliminated by active tubular secretion may result in increased plasma concentrations of one or both drugs due to competitive inhibition of transporters in the renal tubules. Drugs (and/or their metabolites) that are thought to undergo active tubular secretion include acyclovir, allopurinol, aminosalicylic acid, cidofovir, cimetidine, creatine, dyphylline, famciclovir, famotidine, flecainide, ganciclovir, levetiracetam, metformin, methotrexate, midodrine, mycophenolic acid, oseltamivir, pralatrexate, probenecid, procainamide, quinidine, ranitidine, tenofovir, triamterene, trimethoprim, valacyclovir, valganciclovir, zalcitabine, zidovudine, and many of the beta-lactam and quinolone antibiotics.

MANAGEMENT: Patients receiving entecavir with another drug that undergoes active tubular secretion should be monitored for excessive pharmacologic effects of both drugs, and the dosages adjusted as necessary.

Drug and food interactions

Moderate

entecavir food

Applies to: entecavir

ADJUST DOSING INTERVAL: Food delays the oral absorption and reduces the oral bioavailability of entecavir. According to the product labeling, administration of entecavir 0.5 mg with a standard high-fat meal or a light meal resulted in a delay in absorption by 0.25 to 0.75 hours, a decrease in the peak plasma concentration (Cmax) by 44% to 46%, and a decrease in the area under the plasma concentration-time curve (AUC) by 18% to 20% compared to administration in the fasting state.

MANAGEMENT: To ensure maximal oral absorption, entecavir should be administered on an empty stomach at least 2 hours after a meal and 2 hours before the next meal.

Moderate

cefoperazone food

Applies to: cefoperazone

GENERALLY AVOID: Some cephalosporins may occasionally induce a disulfiram-like reaction when coadministered with alcohol. The interaction has been reported for cefamandole, cefoperazone, cefotetan, and moxalactam. These agents contain an N-methylthiotetrazole (NMTT) side chain that may inhibit aldehyde dehydrogenase (ALDH) similar to disulfiram. Following ingestion of alcohol, inhibition of ALDH results in increased concentration of acetaldehyde, the accumulation of which produces an unpleasant physiologic response referred to as the 'disulfiram reaction'. Symptoms include flushing, throbbing in head and neck, throbbing headache, respiratory difficulty, nausea, vomiting, sweating, thirst, chest pain, palpitation, dyspnea, hyperventilation, tachycardia, hypotension, syncope, weakness, vertigo, blurred vision, and confusion. Severe reactions may result in respiratory depression, cardiovascular collapse, arrhythmias, myocardial infarction, acute congestive heart failure, unconsciousness, convulsions, and death. Cefonicid contains a structurally similar side chain but did not produce elevations in blood acetaldehyde or a disulfiram reaction to ethanol in 15 healthy volunteers given single and multiple one gram doses of the drug.

MANAGEMENT: Patients receiving cephalosporins with the NMTT side chain should avoid the concomitant use of alcohol and alcohol-containing products.

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.
