Sintesi

Atazanavir needs an acidic environment for absorption. PPIs sharply reduce atazanavir exposure, risking virologic failure and resistance.

Cosa significa questa interazione in parole semplici

Atazanavir and Rabeprazole can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.

Atazanavir belongs to Anti Virals; Rabeprazole belongs to Gastrointestinal Tract.

Livello di evidenza: High

Perché avviene

Increased gastric pH decreases atazanavir solubility and absorption.

Cosa fare

Avoid in treatment-experienced patients. In naive patients on ritonavir-boosted atazanavir, use only a limited PPI dose taken about 12 hours before and monitor viral load.

Cosa chiedere al farmacista
