Interactions between your drugs

Moderate

lesinurad macimorelin

Applies to: lesinurad and macimorelin

GENERALLY AVOID: Coadministration with inducers of CYP450 3A4 may decrease the plasma concentrations of macimorelin, which is primarily metabolized by the isoenzyme. Although the interaction has not been evaluated in pharmacokinetic studies, the potential for false positive test results should be considered.

MANAGEMENT: The prescribing information for macimorelin recommends discontinuing potent CYP450 3A4 inducers (e.g., carbamazepine, enzalutamide, lumacaftor, mitotane, phenobarbital, phenytoin, rifamycins, St. John's wort) as well as some moderate ones (e.g., bosentan, efavirenz, etravirine, modafinil) prior to macimorelin administration. A sufficient washout period following discontinuation of the inducers is also advised before using macimorelin. No recommendations are available for other, less potent CYP450 3A4 inducers; however, it may be appropriate to follow the same precaution.

Drug and food interactions

Moderate

macimorelin food

Applies to: macimorelin

ADJUST DOSING INTERVAL: Food reduces the oral bioavailability of macimorelin. According to the product labeling, administration with a liquid meal decreased macimorelin peak plasma concentration (Cmax) and systemic exposure (AUC) by 55% and 49%, respectively, compared to administration under fasting conditions (i.e., for at least 8 hours).

MANAGEMENT: Macimorelin should be administered after fasting for at least 8 hours.

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.
