Résumé

Both are phosphodiesterase-3 inhibitors with inotropic and vasodilating actions. Using them together duplicates therapy and increases the risk of hypotension, arrhythmias and, with inamrinone, thrombocytopenia.

Ce que signifie cette interaction, en termes simples

Inamrinone and Milrinone 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.

Niveau de preuve: Moderate

Pourquoi elle survient

Duplicate PDE-3 inhibition causing additive increases in cAMP, inotropy and vasodilation.

Conduite à tenir

Avoid combining the two; use a single PDE-3 inhibitor. If switching, stop the first drug before starting the other and monitor blood pressure and ECG.

Questions à poser à votre pharmacien
