Esmolol is a cardioselective beta-blocker [1]. It functions by blocking the effects of adrenaline and other stress hormones on the heart and blood vessels [1].
What is esmolol used for?
Esmolol is primarily used to control heart rate and blood pressure in specific medical situations [1]. It is often administered intravenously in critical care settings, such as during surgery or in an emergency, to rapidly manage conditions like supraventricular tachycardia (a rapid heart rhythm originating in the upper chambers of the heart) and hypertension (high blood pressure) [1].
How does esmolol work?
As a beta-adrenergic blocking agent, esmolol selectively binds to beta-1 adrenergic receptors. These receptors are predominantly located in the heart. By blocking these receptors, esmolol reduces the heart rate, decreases the force of heart muscle contractions, and lowers blood pressure [1]. Its cardioselectivity means it has a stronger effect on the heart than on beta-2 receptors found in the lungs and blood vessels, potentially leading to fewer side effects like bronchoconstriction [1].
When did esmolol become available?
Information regarding the exact availability date of esmolol is not provided in the given context.
What other beta-blockers are similar to esmolol?
Other beta-blockers include metoprolol, atenolol, and propranolol. Esmolol is distinguished by its very short duration of action, which is achieved through rapid metabolism in the blood by esterases [1]. This pharmacokinetic profile allows for precise titration and quick reversibility of its effects, making it suitable for acute management of cardiac conditions [1].
