摘要
Atazanavir absorption depends on gastric acidity, and dexlansoprazole can markedly lower atazanavir concentrations. This risks loss of virologic suppression and resistance.
用白話說明這項交互作用的意義
Atazanavir and Dexlansoprazole 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; Dexlansoprazole belongs to Gastrointestinal Tract.
為什麼會發生
Higher gastric pH decreases atazanavir solubility and absorption.
處置方式
Avoid PPIs in treatment-experienced patients on atazanavir. In treatment-naive patients follow labeling for a low PPI dose about 12 hours before boosted atazanavir, or choose another antiretroviral.
