Drug and food interactions

Moderate

tacrolimus food

Applies to: Hecoria (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

cinacalcet food

Applies to: Sensipar (cinacalcet)

ADJUST DOSING INTERVAL: Food enhances the oral absorption and bioavailability of cinacalcet. According to the product labeling for cinacalcet, administration with a high-fat meal increased the peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of cinacalcet by 82% and 68%, respectively, compared to administration in the fasting state. The Cmax and AUC were increased 65% and 50%, respectively, when cinacalcet was administered with a low-fat meal compared to fasting.

MANAGEMENT: To ensure maximal oral absorption, cinacalcet should be administered with or immediately after a meal. The tablets should be taken whole and not divided or crushed.

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.
