概要
Gefitinib solubility falls as gastric pH rises, and PPIs can markedly lower gefitinib exposure. This may reduce anticancer efficacy.
この相互作用をわかりやすく説明すると
Esomeprazole and Gefitinib 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.
Esomeprazole belongs to Gastrointestinal Tract; Gefitinib belongs to Oncology.
なぜ起こるのか
Sustained increases in gastric pH reduce gefitinib dissolution and absorption.
対処法
Avoid concomitant PPI use if possible; if a PPI is essential, give gefitinib 12 hours after the PPI dose and consider an alternative acid reducer.
