Resumo
Atazanavir needs an acidic stomach to dissolve, so esomeprazole can markedly reduce its levels. This may lead to virologic failure and development of resistance.
O que esta interação significa em palavras simples
Atazanavir and Esomeprazole 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; Esomeprazole belongs to Gastrointestinal Tract.
Por que acontece
Higher gastric pH decreases atazanavir solubility and absorption.
O que fazer
Avoid PPIs in treatment-experienced patients. In treatment-naive patients on ritonavir-boosted atazanavir, keep the PPI dose to an omeprazole 20 mg equivalent, give it about 12 hours before atazanavir, and monitor viral load.
