Pepsi or Coke? Influence of acid on dasatinib absorption

Dasatinib's bioavailability is highly dependent on gastric pH. When proton-pump inhibitors (PPIs) are co-administered with dasatinib, absorption is significantly reduced. Cola intake at the time of drug administration has been demonstrated to lead to relevant increases in the bioavailability for other acid labile drugs during PPI treatment. This manuscript reviews the relevant literature supporting a strategy of temporarily lowering the gastric pH with a carbonated beverage at the time of drug administration. The use of cola provides an easy to implement way to significantly improve dasatinib bioavailability, especially during concomitant use of a PPI.
