Esmolol is an ultrashort-acting selective β1-antagonist. It primarily decreases heart rate with less of an effect on blood pressure. [1]
Uses
Treat/prevent perioperative tachycardia and hypertension .
Opioid sparing anesthesia.[1]
Contraindications
Absolute contraindications
Precautions
While it is cardioselective at lower doses, use higher doses cautiously in patients with bronchospastic disease. [2]
Extreme caution should be used in patients with bradycardia, hypotension, greater than first degree heart block, cardiogenic shock or heart failure with reduced ejection fraction.[1] Avoid in patients who recently received a calcium channel blocker. [2]
Pharmacology
Pharmacodynamics
Mechanism of action
At normal doses it is a selective β1-antagonist, at higher doses it also inhibits β2 receptors in both bronchial and vascular smooth muscle. [1]
Adverse effects
Pharmacokinetics
Onset of action
Beta-blockade with esmolol can be observed within 2-10 minutes of administration. Onset is typically quicker when administered as a bolus or with a loading dose prior to infusion.[2]
Metabolism
Esmolol is metabolized by red blood cell esterases to inactive metabolites, which are renally excreted. [2]
