Landiolol(Cas 133242-30-5) Usage


Landiolol was launched as iv infusion for the treatment of tachyarrhythmia during surgery. This structurally related derivative of esmolol can be synthesized in 3 linear steps from 3-(4-hydroxyphenyl)propionic acid by successive esterification followed by alkylation of the phenol function with (2S)-glycidyltosylate and opening of the resulting epoxide by the appropriate amine. Landiolol is an ultra short acting PI-adrenergic blocker more cardioselective (βI/β2 = 255) than esmolol (βi/β2 = 32). It showed 6-8 times greater efficiency compared to esmolol in reducing isoproterenol-induced increase in heart rate and ventricular contraction in anesthetized dogs. In clinical trials, landiolol was effective against a variety of arrhythmias with efficacy seen in patients with atrial fibrillation, proxysmal supraventricular tachycardia, ventricular tachycardia and premature complexes. Landiolol produced a doserelated pharmacokinetic behavior, has a rapid onset of action (10 min.) and is rapidly hydrolyzed to inactive acidic metabolites by esterases after iv administration. This results in an ultra-short half-life (approx. 3 min.) and p-blocade, allowing rapid termination of the drug effect by termination of infusion if side effects occur. Hypertension was the most frequent adverse event and resolved in less than 30 min. after drug withdrawal.


Landiolol reduced heart rate significantly without reducing blood pressure, and stabilized hemodynamics. Landiolol is a short-acting beta-adrenergic receptor blocker that can be used to treat atrial tachyarrhythmias in patients with acute heart failure and cardiogenic shock . It's also used to control heart rate in emergencies, intensive care , and perioperative settings. Landiolol is highly selective for the β1 receptor and has a short half-life of 3–4.5 minutes. It's metabolized in the liver and plasma.

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 μg·kg−1·min−1 and the median infusion time was 2 days.
