probenecid cefoperazone

Applies to: ampicillin / probenecid and cefoperazone

MONITOR: Coadministration with probenecid may increase and prolong the serum concentrations of some cephalosporins. The proposed mechanism is competitive inhibition of renal tubular secretion by probenecid, although data suggest other mechanisms may also be involved. The magnitude of interaction appears to be dependent on the dose and timing of administration of probenecid, with greater pharmacokinetic changes reported when larger doses of probenecid are used and when probenecid is administered with or immediately before cephalosporin administration. Increases of 30% to more than 100% in systemic exposure and half-life, and decreases of approximately 30% to 60% in clearance, have been reported for various cephalosporins studied.

MANAGEMENT: Although probenecid has been used therapeutically to enhance serum levels of various beta-lactam antibiotics, the potential for increased adverse effects should be considered when probenecid is added to existing cephalosporin therapy, particularly when the latter is given at high dosages or to patients who are elderly or have renal dysfunction. Adjustment of the cephalosporin dosage may be required in accordance with the individual product labeling. For example, cefotaxime dosage should generally not exceed 6 grams/day when administered with probenecid. Probenecid reportedly does not affect the elimination of ceftazidime or ceftriaxone.

ampicillin probenecid

Applies to: ampicillin / probenecid and ampicillin / probenecid

Probenecid may increase the plasma concentrations and half-lives of penicillins. The mechanism is competitive inhibition by probenecid of the renal tubular secretion of penicillins. While this interaction is often exploited to enhance the antibacterial effect of penicillins, toxicity may occur and should be considered if high penicillin dosages are administered intravenously.

Drug and food interactions

Moderate

ampicillin food

Applies to: ampicillin / probenecid

ADJUST DOSING INTERVAL: Certain penicillins may exhibit reduced gastrointestinal absorption in the presence of food. The therapeutic effect of the antimicrobial may be reduced.

MANAGEMENT: The interacting penicillin should be administered one hour before or two hours after meals. Penicillin V and amoxicillin are not affected by food and may be given without regard to meals.

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.

Therapeutic duplication warnings

Therapeutic duplication is the use of more than one medicine from the same drug category or therapeutic class to treat the same condition. This can be intentional in cases where drugs with similar actions are used together for demonstrated therapeutic benefit. It can also be unintentional in cases where a patient has been treated by more than one doctor, or had prescriptions filled at more than one pharmacy, and can have potentially adverse consequences.

Duplication

Beta-lactam antibiotics

Therapeutic duplication

The recommended maximum number of medicines in the 'beta-lactam antibiotics' category to be taken concurrently is usually one. Your list includes two medicines belonging to the 'beta-lactam antibiotics' category:

  • ampicillin/probenecid
  • cefoperazone

Note: In certain circumstances, the benefits of taking this combination of drugs may outweigh any risks. Always consult your healthcare provider before making changes to your medications or dosage.

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.
