Sintesi

Gefitinib absorption falls when gastric pH is raised, and acid suppression can lower gefitinib exposure and reduce antitumor effect.

Cosa significa questa interazione in parole semplici

Gefitinib and Pantoprazole 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.

Gefitinib belongs to Oncology; Pantoprazole belongs to Gastrointestinal Tract.

Livello di evidenza: High

Perché avviene

Gefitinib is a weak base with pH-dependent solubility, so raised gastric pH reduces its dissolution and absorption.

Cosa fare

Avoid PPIs where possible. If an acid suppressant is essential, use an H2 blocker or antacid given at staggered times, taking gefitinib at least 6 hours apart from them (12 hours from H2 blockers where labeled).

Cosa chiedere al farmacista

  • Does the benefit of taking both outweigh the risk in my case?
  • Do I need any blood test, ECG or other check while on both?
  • What early warning signs should I watch for, and what should I do if they appear?
