概要
Erlotinib absorption depends on an acidic gastric pH, and vonoprazan produces potent, lasting acid suppression. Erlotinib exposure may fall substantially, reducing efficacy.
この相互作用をわかりやすく説明すると
Erlotinib and Vonoprazan 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; Vonoprazan belongs to Gastrointestinal Tract.
なぜ起こるのか
Higher gastric pH from vonoprazan reduces the solubility and absorption of erlotinib.
対処法
Avoid vonoprazan and other potent acid suppressants where possible. If acid suppression is essential, monitor for reduced response to erlotinib.
