概要
Prolonged rabeprazole therapy can cause hypomagnesemia, which together with low potassium raises the risk of QT prolongation and ventricular arrhythmia with domperidone. The effect is uncommon, typically follows months of PPI use, and matters most in older patients, those on diuretics or digoxin, and those with heart disease or other QT-prolonging drugs.
この相互作用をわかりやすく説明すると
Domperidone and Rabeprazole 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.
Domperidone belongs to Gastrointestinal Tract; Rabeprazole belongs to Gastrointestinal Tract.
なぜ起こるのか
Indirect pharmacodynamic: PPI-related hypomagnesemia reduces repolarisation reserve and potentiates the hERG-mediated QT prolongation of domperidone.
対処法
Measure magnesium and potassium before starting domperidone in patients on long-term rabeprazole and correct any deficiency. Use the lowest effective domperidone dose for the shortest duration.
