Interactions between your drugs

Moderate

tenofovir oteseconazole

Applies to: AccessPak for HIV PEP Basic (emtricitabine / tenofovir disoproxil) and oteseconazole

ADJUST DOSE: Coadministration with oteseconazole may increase the plasma concentrations of drugs that are substrates of the breast cancer resistance protein (BCRP), which may increase the risk of adverse effects associated with these drugs. The proposed mechanism is decreased clearance due to inhibition of BCRP-mediated intestinal and/or hepatic transport by oteseconazole. When administered with rosuvastatin, a BCRP substrate, oteseconazole increased rosuvastatin peak plasma concentration (Cmax) and systemic exposure (AUC 0-24h) by 118% and 114%, respectively.

MANAGEMENT: When concomitant use of oteseconazole is required, the lowest possible starting dosage or a reduction of the existing dosage of BCRP substrates should be considered. The prescribing information for concomitant medications should be consulted to assess the benefits versus risks of coadministration of a BCRP inhibitor like oteseconazole and for any dosage adjustments that may be required. Patients should be closely monitored for clinical response and adverse effects, and the dosage(s) of concomitant medication(s) further adjusted as necessary.

Drug and food interactions

Moderate

oteseconazole food

Applies to: oteseconazole

ADJUST DOSING INTERVAL: Food enhances the oral bioavailability of oteseconazole. When administered with a high-fat, high-calorie meal (800 to 1000 calories; 50% fat), oteseconazole peak plasma concentration (Cmax) and systemic exposure (AUC 0-72h) increased by 45% and 36%, respectively. However, no significant differences were observed with a low-fat, low-calorie meal.

MANAGEMENT: Oteseconazole should be administered with food.

Minor

tenofovir food

Applies to: AccessPak for HIV PEP Basic (emtricitabine / tenofovir disoproxil)

Food enhances the oral absorption and bioavailability of tenofovir, the active entity of tenofovir disoproxil fumarate. According to the product labeling, administration of the drug following a high-fat meal increased the mean peak plasma concentration (Cmax) and area under the concentration-time curve (AUC) of tenofovir by approximately 14% and 40%, respectively, compared to administration in the fasting state. However, administration with a light meal did not significantly affect the pharmacokinetics of tenofovir compared to administration in the fasting state. Food delays the time to reach tenofovir Cmax by approximately 1 hour. Tenofovir disoproxil fumarate may be administered without regard to meals.

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.
