Esmolol is a beta-adrenergic blocker sold in the U.S. under 3 brand and generic names, for angina pectoris, heart failure and hypertension. Below: what the FDA label says, every product that contains it, what the pills look like, and its recall record.
From the FDA label for Brevibloc (application NDA019386). Other esmolol products — different forms, different strengths — are dosed differently. Follow the label for the one you were prescribed.
Dosing for the Treatment of Supraventricular Tachycardia or Noncompensatory Sinus Tachycardia BREVIBLOC injection is administered by continuous intravenous infusion with or without a loading dose. Additional loading doses and/or titration of the maintenance infusion (step-wise dosing) may be necessary based on desired ventricular response. In the absence of loading doses, continuous infusion of a single concentration of esmolol reaches pharmacokinetic and pharmacodynamic steady-state in about 30 minutes. The effective maintenance dose for continuous and step-wise dosing is 50 to 200 mcg per kg per minute, although doses as low as 25 mcg per kg per minute have been adequate. Dosages greater than 200 mcg per kg per minute provide little added heart rate lowering effect, and the rate of adverse reactions increases. Maintenance infusions may be continued for up to 48 hours. 2.2 Intraoperative and Postoperative Tachycardia and Hypertension In this setting it is not always advisable to slowly titrate to a therapeutic effect. Therefore two dosing options are presented: immediate control and gradual control. Immediate Control • Administer 1 mg per kg as a bolus dose over 30 seconds followed by an infusion of 150 mcg per kg per min if necessary. • Adjust the infusion rate as required to maintain desired heart rate and blood pressure. Refer to Maximum Recommended Doses below. Gradual…
Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. The following adverse reaction rates are based on use of BREVIBLOC (Esmolol Hydrochloride) injection in clinical trials involving 369 patients with supraventricular tachycardia and over 600 intraoperative and postoperative patients enrolled in clinical trials. Most adverse effects observed in controlled clinical trial settings have been mild and transient. The most important and common adverse effect has been hypotension [see Warnings and Precautions ( 5- 5.1)]. Deaths have been reported in post-marketing experience occurring during complex clinical states where BREVIBLOC injection was presumably being used simply to control ventricular rate [see Warnings and Precautions ( 5- 5.5)]. Clinical Trial Adverse Reactions (Frequency <3%) Psychiatric Disorders Confusional state and agitation (~2%) Anxiety, depression and abnormal thinking (<1%) Nervous System Disorders Headache (~ 2%) Paresthesia, syncope, speech disorder, and lightheadedness (<1%) Convulsions (<1%), with one death Vascular Disorders Peripheral ischemia (~1%) Pallor and flushing (<1%) Gastrointestinal Disorders Vomiting…

Esmolol Hydrochloride) injection is contraindicated in patients with: • Severe sinus bradycardia: May precipitate or worsen bradycardia resulting in cardiogenic shock and cardiac arrest [see Warnings and Precautions ( 5- 5.2)]. • Heart block greater than first degree: Second- or third-degree atrioventricular block may precipitate or worsen bradycardia resulting in cardiogenic shock and cardiac arrest [see Warnings and Precautions ( 5- 5.2)]. • Sick sinus syndrome: May precipitate or worsen bradycardia resulting in cardiogenic shock and cardiac arrest [see Warnings and Precautions ( 5- 5.2)]. • Decompensated heart failure: May worsen heart failure. • Cardiogenic shock: May precipitate further cardiovascular collapse and cause cardiac arrest. • IV administration of cardiodepressant calcium-channel antagonists (e.g., verapamil) and BREVIBLOC injection in close proximity (i.e., while cardiac effects from the other are still present); fatal cardiac arrests have occurred in patients receiving BREVIBLOC injection and intravenous verapamil. • Pulmonary hypertension: May precipitate cardiorespiratory compromise. • Hypersensitivity reactions, including anaphylaxis, to esmolol or any of the inactive ingredients of the product (cross-sensitivity between beta blockers is possible).
Concomitant use of BREVIBLOC injection with other drugs that can lower blood pressure, reduce myocardial contractility, or interfere with sinus node function or electrical impulse propagation in the myocardium can exaggerate BREVIBLOC injection’s effects on blood pressure, contractility, and impulse propagation. Severe interactions with such drugs can result in, for example, severe hypotension, cardiac failure, severe bradycardia, sinus pause, sinoatrial block, atrioventricular block, and/or cardiac arrest. In addition, with some drugs, beta blockade may precipitate increased withdrawal effects. (See clonidine, guanfacine, and moxonidine below.) BREVIBLOC injection should therefore be used only after careful individual assessment of the risks and expected benefits in patients receiving drugs that can cause these types of pharmacodynamic interactions, including but not limited to: • Digitalis glycosides: Concomitant administration of digoxin and BREVIBLOC injection leads to an approximate 10% to 20% increase of digoxin blood levels at some time points. Digoxin does not affect BREVIBLOC injection pharmacokinetics. Both digoxin and beta blockers slow atrioventricular conduction and decrease heart rate. Concomitant use increases the risk of bradycardia. • Anticholinesterases: BREVIBLOC injection prolonged the duration of succinylcholine-induced neuromuscular blockade and…
