Summary
Dasatinib dissolves best in acid, and rabeprazole suppresses gastric acid for many hours. Dasatinib exposure may fall significantly, risking reduced response in leukemia treatment.
What this interaction means in plain words
Dasatinib and Rabeprazole 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.
Dasatinib belongs to Oncology; Rabeprazole belongs to Gastrointestinal Tract.
Why it happens
Higher gastric pH reduces the pH-dependent solubility and absorption of dasatinib.
What to do
Avoid PPIs with dasatinib. If acid suppression is needed, use an antacid taken at least 2 hours before or after dasatinib, or consider a short-acting H2 blocker given 2 hours before dasatinib.
