التداخل بين كابوتيغرافير وريفابوتين

Rifabutin capsules are contraindicated in patients being treated with cabotegravir/rilpivirine prolonged-release injectable suspension (see PRECAUTIONS-Drug Interactions, Table 2 ).

Co-administration of rifabutin with cabotegravir/rilpivirine prolonged-release injectable suspension is contraindicated.

Therefore, co-administration with antiretroviral and anti-HCV drugs metabolized by CYP3A is not recommended or there may be a need to increase the dose of antiretroviral or anti-HCV drugs (see PRECAUTIONS-Drug Interactions ).

The concomitant use of protease inhibitors may require at least a 50% reduction in rifabutin dose, and depending on the protease inhibitor, an adjustment of the antiretroviral drug dose.

Co-administration with antiretroviral drugs metabolized by CYP3A, including but not limited to products containing bictegravir, elvitegravir, oral rilpivirine, or doravirine and anti-HCV drugs including but not limited to sofosbuvir (alone or in combination) may decrease plasma concentrations of those drugs, which may lead to loss of virologic response and possible…

Drug Interactions with VOCABRIA ↓ = Decrease; PrEP = Pre-exposure prophylaxis. a Rifabutin can be coadministered with cabotegravir; however, it is contraindicated with CABENUVA for HIV-1 treatment.

Prior to initiating oral therapy, note that use of CABENUVA (cabotegravir extended-release injectable suspension; rilpivirine extended-release injectable suspension) with rifabutin is contraindicated for the treatment of HIV-1 infection.

Drugs without Clinically Significant Interactions with Cabotegravir Based on drug interaction study results, the following drugs can be coadministered with cabotegravir without a dose adjustment: etravirine, midazolam, oral contraceptives containing levonorgestrel and ethinyl estradiol, rifabutin, and rilpivirine [see Clinical Pharmacology ( 12.3 )] .
