Esmolol
Brevibloc (esmolol) is a short-acting, intravenous beta-blocker used primarily in hospital settings for rapid heart rate control. It is commonly employed in critical care and surgical environments to manage acute supraventricular arrhythmias and perioperative hemodynamic fluctuations. Its rapid onset and titratable nature make it particularly useful when precise control of heart rate and blood pressure is essential.

Used for rate control in supraventricular tachyarrhythmias including atrial fibrillation and atrial flutter, as well as acute management of perioperative hypertension with tachycardia. It is administered in critical care and surgical settings when rapid, short-term heart rate reduction is needed.
Brevibloc is a selective beta-1 adrenergic receptor blocker that reduces heart rate and myocardial oxygen demand by blocking the effects of epinephrine on the heart. Its ultra-short half-life (approximately 9 minutes) allows for rapid onset and quick offset of effects when the infusion is discontinued.
Administered only via intravenous infusion in monitored healthcare settings due to its rapid-acting nature. Contraindicated in patients with severe bradycardia, heart block, or decompensated heart failure. May cause hypotension and requires careful dose titration. Therapy duration is typically short-term as it is not intended for long-term use.
