Milrinone dosing in heart failure lacks clear guidelines, with clinical practice often limited by concerns over arrhythmias, hypotension, and renal clearance.
This review highlights the lack of clear guidelines for milrinone dosing in end-stage heart failure and examines the balance between its hemodynamic benefits and adverse events.
Milrinone is an invaluable agent in the treatment of end-stage heart failure patients who are refractory to optimal medical therapy. In addition to its use in acute decompensated heart failure, milrinone can also be employed as a home infusion therapy or a bridge to cardiac transplant. Concerns about its adverse effects, such as an increased risk of arrhythmias and hypotension, often limit the doses of milrinone used in clinical practice. In addition, milrinone is infrequently used or avoided entirely in patients with acute renal failure or end-stage renal disease because the drug is primarily cleared by renal excretion. Despite these concerns, studies that comprehensively reconcile the dose-response relationship and adverse events are scarce, and no clear provisions exist to guide milrinone dosing. After a brief discussion of the pharmacokinetics of milrinone, this article examines milrinone dosing, observed hemodynamic benefits, and documented adverse events across different studies.
Chong et al. (Wed,) conducted a review in End-stage heart failure and acute decompensated heart failure. Milrinone was evaluated. Milrinone dosing in heart failure lacks clear guidelines, with clinical practice often limited by concerns over arrhythmias, hypotension, and renal clearance.
