Interactions between your drugs

Moderate

abiraterone apixaban

Applies to: abiraterone and Eliquis (apixaban)

MONITOR: Coadministration with inhibitors of CYP450 3A4 and/or P-glycoprotein (P-gp) may increase the plasma concentrations of apixaban, which is a substrate of both the isoenzyme and efflux transporter. When apixaban was coadministered with the moderate CYP450 3A4 and P-gp inhibitor diltiazem (360 mg once a day), mean apixaban peak plasma concentration (Cmax) and systemic exposure (AUC) increased by 1.3- and 1.4-fold, respectively. Likewise, coadministration with the P-gp inhibitor naproxen (500 mg single dose) increased the mean apixaban Cmax and AUC by approximately 1.6- and 1.5-fold, respectively.

MANAGEMENT: No dosage adjustment for apixaban is required during concomitant therapy with lone inhibitors of CYP450 3A4 or P-gp, or moderate or weak dual inhibitors of both CYP450 3A4 and P-gp. However, caution may be advisable. Closer monitoring of the pharmacologic effects of apixaban may be appropriate whenever a CYP450 3A4 or P-gp inhibitor is added to or withdrawn from therapy. Patients should be routinely evaluated for signs and symptoms suggesting blood loss such as a drop in hemoglobin and/or hematocrit, hypotension, or fetal distress (in pregnant women).

Drug and food interactions

Moderate

abiraterone food

Applies to: abiraterone

ADJUST DOSING INTERVAL: Food may significantly increase the oral bioavailability of some formulations of abiraterone acetate. Compared to administration in the fasted state, abiraterone peak plasma concentration (Cmax) and systemic exposure (AUC) were approximately 7- and 5-fold higher, respectively, when a single dose of abiraterone acetate was administered with a low-fat meal (7% fat; 300 calories) and approximately 17- and 10-fold higher, respectively, when it was administered with a high-fat meal (57% fat; 825 calories). Given the normal variation in the content and composition of meals, taking abiraterone acetate with meals has the potential to result in increased and highly variable exposures. The safety of these increased exposures during multiple dosing has not been assessed. However, the abiraterone acetate 125 mg tablet, commonly marketed as Yonsa, was found to have an approximately 6.5-fold higher Cmax and 4.4-fold higher AUC when a single dose of 500 mg (4 tablets) was administered with a high-fat meal (56% - 60% fat, 900 - 1000 calories) compared to overnight fasting in healthy volunteers. These differences were not considered clinically significant for this formulation.

MANAGEMENT: Some formulations of abiraterone acetate must be taken on an empty stomach. No food should be consumed for at least two hours before and one hour after the abiraterone acetate dose. However, the abiraterone acetate 125 mg tablet, commonly marketed as Yonsa, can be taken with or without food. The manufacturer's product labeling should be consulted for specific guidance.

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.
