概要

Atazanavir absorption depends on gastric acidity, and lansoprazole markedly lowers atazanavir concentrations. This risks loss of virologic suppression and development of resistance.

この相互作用をわかりやすく説明すると

Atazanavir and Lansoprazole 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; Lansoprazole belongs to Gastrointestinal Tract.

エビデンスレベル: High

なぜ起こるのか

Higher gastric pH decreases atazanavir solubility and hence absorption.

対処法

Avoid PPIs in treatment-experienced patients on atazanavir. In treatment-naive patients, follow labeling for a low PPI dose taken about 12 hours before ritonavir-boosted atazanavir, or use an alternative antiretroviral.
