概要
Infigratinib absorption depends on gastric acidity, and famotidine raises gastric pH. This can lower infigratinib exposure and reduce its antitumor effect.
この相互作用をわかりやすく説明すると
Famotidine and Infigratinib 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.
なぜ起こるのか
Increased gastric pH reduces the pH-dependent solubility and absorption of infigratinib.
対処法
Avoid concurrent H2 antagonists where possible. If unavoidable, give infigratinib 2 hours before or 10 hours after famotidine.
