Atazanavir Capsules <> Yosprala

Relevance: 15.11.2023 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:

Using atazanavir together with omeprazole is not recommended. By reducing stomach acid, omeprazole can decrease the absorption and blood levels of atazanavir and make the medication less effective against HIV. Your doctor or pharmacist may be able to offer suggestions on safer alternatives if you require treatment for stomach acid or ulcer while you are being treated with atazanavir. 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:

GENERALLY AVOID: Concurrent use of proton pump inhibitors may decrease the oral bioavailability of atazanavir and substantially reduce its concentrations in plasma. Atazanavir solubility decreases with increasing pH, thus inhibition of gastric acid secretion may interfere with dissolution of the drug.

MANAGEMENT: Given the risk of reduced viral susceptibility and resistance development associated with subtherapeutic antiretroviral drug levels, use of proton pump inhibitors is not recommended in treatment-experienced patients receiving atazanavir with or without ritonavir or cobicistat. In treatment-naive patients receiving atazanavir with ritonavir or cobicistat, it is recommended that the dose of the proton-pump inhibitor not exceed 20 mg/day of omeprazole, or equivalent, and doses should be separated by 12 hours. Atazanavir without ritonavir or cobicistat should not be coadministered with proton pump inhibitors in treatment-naive patients.
