摘要
Erlotinib dissolves best at low gastric pH, and lansoprazole suppresses gastric acid so much that erlotinib absorption falls substantially (AUC reduction of about half with omeprazole). Tumour exposure may be inadequate.
用白話說明這項交互作用的意義
Erlotinib 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.
Erlotinib belongs to Oncology; Lansoprazole belongs to Gastrointestinal Tract.
為什麼會發生
Raised gastric pH reduces erlotinib solubility and absorption
處置方式
Avoid PPIs; if acid suppression is needed, give erlotinib 2 hours before or 10 hours after an H2 antagonist, or use antacids separated by several hours.
