Resumo
Prolonged proton pump inhibitor use can cause hypomagnesemia and secondary hypokalemia or hypocalcemia, which increase vulnerability to QT prolongation and torsades de pointes. Domperidone has a dose-related QT-prolonging effect, so electrolyte depletion raises its arrhythmic risk. Risk is highest in older patients, those with cardiac disease and those taking other QT-prolonging drugs or diuretics.
O que esta interação significa em palavras simples
Dexlansoprazole and Domperidone can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Dexlansoprazole belongs to Gastrointestinal Tract; Domperidone belongs to Gastrointestinal Tract.
Por que acontece
Pharmacodynamic: PPI-induced hypomagnesemia (and secondary hypokalemia) potentiates the QTc-prolonging effect of domperidone. No relevant pharmacokinetic interaction is expected.
O que fazer
Use the lowest effective domperidone dose for the shortest time and correct magnesium, potassium and calcium before starting. Recheck magnesium periodically in patients on long-term PPI therapy, particularly if they also take diuretics or digoxin.
O que perguntar ao farmacêutico
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
