摘要
Omeprazole lowers dacomitinib concentrations, which may reduce its antitumour efficacy. Dacomitinib absorption depends on gastric acidity.
用白話說明這項交互作用的意義
Dacomitinib and Omeprazole 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.
Dacomitinib belongs to Oncology; Omeprazole belongs to Gastrointestinal Tract.
為什麼會發生
Increased gastric pH reduces dacomitinib solubility and absorption.
處置方式
Avoid PPIs with dacomitinib. If acid suppression is needed, use a locally acting antacid or an H2 antagonist, dosing dacomitinib at least 6 hours before or 10 hours after the H2 blocker.
