Clinical role and efficacy of landiolol in the intensive care unit

Abstract

Beta-adrenergic receptor blockers have proved to be effective for the management of various cardiovascular diseases and the prevention of perioperative cardiac events and cerebrovascular accidents. Landiolol is a short-acting beta-blocker, with high beta 1-selectivity and a short duration of action. We thought landiolol was valuable and suitable for intensive care unit (ICU) patients, and conducted a retrospective study. The records of 80 patients (58 post-surgical patients; group S and 22 internal medicine patients; group IM) were reviewed. Thirty-seven (64%) of the group S patients were post-coronary artery bypass graft surgery, and the IM group consisted mostly of patients with acute myocardial infarction. The most common indication for landiolol in group S was the prevention of myocardial ischemia (50%), and in group IM, it was atrial fibrillation (45%). The median infusion rate of landiolol was 5 microg.kg(-1).min(-1) and the median infusion time was 2 days. Twenty-six patients were continued on oral beta-adrenergic receptor blockers. Landiolol reduced heart rate significantly without reducing blood pressure, and stabilized hemodynamics. We confirmed that landiolol is valuable as a bridge to starting oral beta-adrenergic receptor blockers and as an anti-arrhythmic agent, and that it is suitable for ICU patients due to its high beta 1-selectivity and rapid onset and offset of action.
