Atazanavir ve Rabeprazol etkileşimi

In HIV-treatment-experienced adult patients: Coadministration of REYATAZ with PPIs is not recommended.

Reduced plasma concentrations of atazanavir are expected if proton-pump inhibitors, antacids, buffered medications, or H 2 -receptor antagonists are administered with REYATAZ [see Dosage and Administration ( 2.3 , 2.4 , 2.5 and 2.6) ] .

Proton-pump inhibitors: omeprazole ↓ atazanavir Coadministration of REYATAZ with or without ritonavir and omeprazole may result in loss of virologic response and development of resistance.

In HIV-treatment-naive adult patients: The proton-pump inhibitor (PPI) dose should not exceed a dose comparable to omeprazole 20 mg and must be taken approximately 12 hours prior to the REYATAZ 300 mg with ritonavir 100 mg dose.

Decreased exposure of some antiretroviral drugs (e.g., rilpivirine, atazanavir, and nelfinavir) when used concomitantly with rabeprazole may reduce antiviral effect and promote the development of drug resistance.

Increased exposure of other antiretroviral drugs (e.g., saquinavir) when used concomitantly with rabeprazole may increase toxicity.

Atazanavir : See prescribing information for atazanavir for dosing information.

Table 2: Clinically Relevant Interactions Affecting Drugs Co-Administered with ACIPHEX Delayed-Release Tablets and Interactions with Diagnostics Antiretrovirals Clinical Impact: The effect of PPI on antiretroviral drugs is variable.

There are other antiretroviral drugs which do not result in clinically relevant interactions with rabeprazole.
