摘要
Gefitinib needs an acidic stomach for adequate absorption, and acid suppression with a PPI lowers its exposure markedly. This may reduce anticancer efficacy.
用白話說明這項交互作用的意義
Dexlansoprazole 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.
Dexlansoprazole belongs to Gastrointestinal Tract; Gefitinib belongs to Oncology.
為什麼會發生
Increased gastric pH reduces gefitinib solubility and absorption.
處置方式
Avoid PPIs if possible. If one is required, take gefitinib 12 hours after the PPI dose, though this may not fully prevent the effect.
