Edit list (add/remove drugs)

Interactions between your drugs

Moderate

tacrolimus lumateperone

Applies to: Prograf (tacrolimus) and lumateperone

MONITOR: Coadministration of sirolimus or tacrolimus with other drugs that are also metabolized by CYP450 3A4 may result in elevated plasma concentrations of the macrolide immunosuppressant and/or the coadministered drug(s). The mechanism is decreased drug clearance due to competitive inhibition of CYP450 3A4 activity. Although clinical data are lacking, the possibility of prolonged and/or increased pharmacologic effects of the drugs should be considered.

MANAGEMENT: Pharmacologic responses and/or plasma drug levels should be monitored more closely whenever a macrolide immunosuppressant or another substrate of CYP450 3A4 is added to or withdrawn from therapy, and the dosage(s) adjusted as necessary.

Drug and food interactions

Moderate

tacrolimus food

Applies to: Prograf (tacrolimus)

ADJUST DOSING INTERVAL: Consumption of food has led to a 27% decrease in the bioavailability of orally administered tacrolimus.

MANAGEMENT: Tacrolimus should be administered at least one hour before or two hours after meals.

GENERALLY AVOID: Grapefruit juice has been reported to increase tacrolimus trough concentrations. Data are limited, but inhibition of the CYP450 enzyme system appears to be involved.

MANAGEMENT: The clinician may want to recommend that the patient avoid ingesting large amounts of grapefruit juice while taking tacrolimus.

Moderate

lumateperone food

Applies to: lumateperone

GENERALLY AVOID: Grapefruit and grapefruit juice may increase the plasma concentrations of lumateperone. The proposed mechanism is inhibition of CYP450 3A4-mediated first-pass metabolism in the gut wall by certain compounds present in grapefruit. Inhibition of hepatic CYP450 3A4 may also contribute. The interaction has not been studied with grapefruit but has been reported for other CYP450 3A4 inhibitors. In a drug interaction study, the strong CYP450 3A4 inhibitor itraconazole increased lumateperone peak plasma concentration (Cmax) and systemic exposure (AUC) approximately 3.5- and 4-fold, respectively, while diltiazem (a moderate CYP450 3A4 inhibitor) increased lumateperone Cmax and AUC approximately 2- and 2.5-fold, respectively. In general, the effect of grapefruit juice is concentration-, dose- and preparation-dependent, and can vary widely among brands. Certain preparations of grapefruit juice (e.g., high dose, double strength) have sometimes demonstrated potent inhibition of CYP450 3A4, while other preparations (e.g., low dose, single strength) have typically demonstrated moderate inhibition.

When administered with a high-fat meal, lumateperone Cmax decreased by 33% while its AUC increased by 9% and its median time to peak plasma concentration (Tmax) was delayed by about 1 hour.

MANAGEMENT: Lumateperone should be administered with food. Coadministration of grapefruit or grapefruit juice with lumateperone should be avoided.

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.
