Sintesi
Atazanavir needs an acidic environment to dissolve, and omeprazole substantially lowers its plasma concentrations. This can cause loss of virologic control and resistance.
Cosa significa questa interazione in parole semplici
Atazanavir and Omeprazole 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; Omeprazole belongs to Gastrointestinal Tract.
Perché avviene
Increased gastric pH reduces atazanavir solubility and absorption.
Cosa fare
Avoid PPIs in treatment-experienced patients. In naive patients, use no more than omeprazole 20 mg daily, taken about 12 hours before ritonavir-boosted atazanavir.
