Esmolol, sold under the brand name Brevibloc, is a cardio selective beta1 receptor blocker with rapid onset,[3] a very short duration of action, and no significant intrinsic sympathomimetic or membrane stabilising activity at therapeutic dosages.

It is a class II antiarrhythmic.[4] Esmolol decreases the force and rate of heart contractions by blocking beta-adrenergic receptors of the sympathetic nervous system, which are found in the heart and other organs of the body. Esmolol prevents the action of two naturally occurring substances: epinephrine and norepinephrine.[5]

It was patented in 1980 and approved for medical use in 1987.[6]
