omeprazole oral and atazanavir oral

omeprazole oral will decrease the level or effect of atazanavir oral by reducing stomach acidity. This interaction may occur when both drugs are taken by mouth. Proton pump inhibitors (PPI) reduce blood levels of atazanavir. PPI dose should not exceed a dose comparable to omeprazole 20 mg and must be taken about 12 hours before atazanavir in patients who just started atazanavir. PPIs are not recommended in people who have been taking atazanavir for some time.

omeprazole oral and atazanavir oral

omeprazole oral will decrease the level or effect of atazanavir oral by increasing gastric pH. Applies only to oral form of both agents. Atazanavir solubility decreases as pH increases. Substantially reduced plasma concentrations of atazanavir are expected if PPIs are coadministered. PPI dose should not exceed a dose comparable to omeprazole 20 mg and must be taken ~12 h before atazanavir/ritonavir in treatment naive-patients. PPIs are not recommended in treatment-experienced taking atazanavir.
