FDA approves short-acting beta-blocker
Brand name: Rapiblyk
Generic name: landiolol
Manufacturer: AOP Health
Approval date: November 22, 2024
Rapiblyk (landiolol) is an ultra-short-acting, beta-1 selective adrenergic receptor antagonist that’s indicated for use in the hospital critical care setting for the treatment of supraventricular tachycardia (SVT; afib and atrial flutter).
According to a manufacturer press release, landiolol is characterized by a fast onset of action and rapid reduction in heart rate without significantly lowering BP.
Efficacy
Approval was based on data from 5 randomized, double-blind, placebo-controlled trials involving 317 adults with SVT who were treated with landiolol. Heart rate decrease (defined as a >20% decrease in heart rate or heart rate <100 bpm or at least intermittent cessation of the arrhythmia) occurred in 40% to 90% of landiolol-treated patients within about 10 minutes, vs. 0 to 11% of those who received placebo.
Safety
The most common adverse reaction reported in clinical trials was hypotension (9.9%).
Recommended dose
Rapiblyk is administered as a continuous IV infusion in a monitored setting, titrated to ventricular rate.
