Determining the interaction of Bictegravir, emtricitabine, and tenofovir and Escavite D and the possibility of their joint administration.

Check result:

Bictegravir, emtricitabine, and tenofovir <> Escavite D

Relevance: 26.07.2022 Reviewer: Shkutko P.M., M.D., in

In the database of official manuals used in the service creation an interaction registered by statistical results of studies was found, which can either lead to negative consequences for the patient health or strengthen a mutual positive effect. A doctor should be consulted to address the issue of joint drug administration.

Consumer:

Products that contain aluminum, calcium, iron, magnesium or other minerals such as antacids and supplements may interfere with the absorption of bictegravir and reduce its effectiveness in treating HIV infection. Additionally, it may lead to development of viral resistance to this and various other HIV medications that are currently used for treatment. When used with antacids, you should generally take bictegravir on an empty stomach at least two hours before the antacid. Avoid taking bictegravir simultaneously with, or 2 hours after, antacid dosing whenever possible. When used with multivitamin or mineral supplements, you may take bictegravir and supplements together at the same time, but with food. Avoid taking bictegravir on an empty stomach simultaneously with, or 2 hours after, dosing of supplements. Talk to your doctor or pharmacist if you have questions on how to take this or other medications you are prescribed, or if you have trouble separating the dosing times. Your doctor may be able to prescribe alternatives that do not interact. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Professional:

ADJUST DOSING INTERVAL: Concurrent administration of medications or oral supplements containing polyvalent cations such as aluminum, calcium, iron, or magnesium may decrease the oral bioavailability of bictegravir. The mechanism of interaction has not been described.

Antacids - In healthy volunteers, administration of a single 50 mg dose of bictegravir simultaneously with a 20 mL dose of maximum strength antacid (aluminum hydroxide-magnesium hydroxide-simethicone 80 mg-80 mg-8 mg/mL) under fasted conditions decreased mean bictegravir peak plasma concentration (Cmax) and systemic exposure (AUC) by approximately 80%, whereas simultaneous administration under fed conditions decreased mean bictegravir Cmax and AUC by approximately 50%. When the antacid was administered 2 hours before bictegravir under fasted conditions, mean Cmax and AUC of bictegravir decreased by 58% and 52%, respectively. However, when the antacid was administered 2 hours after bictegravir under fasted conditions, mean Cmax and AUC of bictegravir decreased by just 7% and 13%, respectively.

Calcium - In healthy volunteers, administration of a single 50 mg dose of bictegravir simultaneously with a 1200 mg dose of calcium carbonate under fasted conditions decreased mean Cmax and AUC of bictegravir by 42% and 33%, respectively, while simultaneous administration under fed conditions had no significant effects on the Cmax and AUC of bictegravir.

Iron - In healthy volunteers, administration of a single 50 mg dose of bictegravir simultaneously with a 324 mg dose of ferrous fumarate under fasted conditions decreased mean Cmax and AUC of bictegravir by 71% and 63%, respectively, while simultaneous administration under fed conditions decreased mean bictegravir Cmax and AUC by just 25% and 16%, respectively.

Sucralfate - Sucralfate contains the polyvalent cation aluminum. Concomitant administration with bictegravir is expected to lead to reduced plasma concentrations of bictegravir similar to that observed with antacids. However, data are not available.

MANAGEMENT: When used with antacids containing aluminum, magnesium or calcium, bictegravir may be taken under fasting conditions 2 hours before the antacids. Routine administration of bictegravir simultaneously with, or 2 hours after, antacids containing aluminum, magnesium or calcium is not recommended. When used with supplements containing calcium or iron, bictegravir and the supplements may be taken together with food. Routine administration of bictegravir under fasting conditions simultaneously with, or 2 hours after, supplements containing calcium or iron is not recommended.
