Sintesi
Infigratinib has pH-dependent solubility, so reduced gastric acidity lowers its absorption. Dexlansoprazole may decrease infigratinib exposure and weaken its anticancer effect.
Cosa significa questa interazione in parole semplici
Dexlansoprazole 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.
Perché avviene
Increased gastric pH reduces infigratinib solubility and absorption.
Cosa fare
Avoid PPIs with infigratinib. If acid reduction is required, use a locally acting antacid separated from infigratinib by the interval stated in the labeling.
