Interactions between your drugs

Moderate

temsirolimus metreleptin

Applies to: Torisel (temsirolimus) and metreleptin

MONITOR: Treatment with metreleptin, a recombinant analog of human leptin, may affect the pharmacokinetics of drugs that are primarily metabolized by CYP450 isoenzymes. In leptin-deficient obese mice, administration of leptin has been shown to alter the hepatic levels of some CYP450 isoenzymes.

MANAGEMENT: Caution is advised when metreleptin is prescribed to patients receiving drugs with a narrow therapeutic index that are substrates of CYP450 isoenzymes, such as macrolide immunosuppressants, oral contraceptives, cyclosporine, theophylline, and warfarin. Clinical and laboratory monitoring are recommended following the initiation, discontinuation or change of dosage of metreleptin, and the individual dosage of the concomitant agents adjusted as needed.

Drug and food interactions

Moderate

temsirolimus food

Applies to: Torisel (temsirolimus)

GENERALLY AVOID: Coadministration of temsirolimus with grapefruit juice may increase the plasma concentrations of sirolimus, a major active metabolite of temsirolimus and known substrate of CYP450 3A4. The proposed mechanism is inhibition of CYP450 3A4-mediated metabolism by certain compounds present in grapefruits.

MANAGEMENT: Patients treated with temsirolimus should preferably avoid the consumption of grapefruit or grapefruit juice.

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.
