Esmolol

Excerpt

Esmolol, or esmolol hydrochloride, is an intravenous cardioselective β-1 adrenergic antagonist. This drug has received approval from the United States Food and Drug Administration (FDA) for short-term use in managing supraventricular tachycardia, including rapid ventricular rates in individuals with atrial fibrillation or atrial flutter, and hypertension induced by intubation. Esmolol is a valuable emergency medication for focal atrial tachycardia, particularly in individuals experiencing active bronchospasm. Furthermore, esmolol has proven to be a safe and efficient medication for controlling blood pressure during surgery due to its short half-life. The drug is also indicated in cases of sinus tachycardia, where a rapid heartbeat requires immediate intervention, especially in the case of acute coronary syndrome.
