Interactions between your drugs

Moderate

temsirolimus erdafitinib

Applies to: temsirolimus and erdafitinib

GENERALLY AVOID: Coadministration with erdafitinib may alter the plasma concentrations of drugs that are substrates of the CYP450 3A4 isoenzyme, resulting in increased toxicity or decreased efficacy of these drugs. In vitro, erdafitinib has been shown to be a time-dependent inhibitor as well as inducer of CYP450 3A4. However, no pharmacokinetic data are available from drug interaction studies.

MANAGEMENT: Concomitant use of erdafitinib and sensitive CYP450 3A4 substrates or substrates with narrow therapeutic ranges should generally be avoided.

Drug and food interactions

Moderate

temsirolimus food

Applies to: 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.
