For Healthcare Professionals
Applies to esmolol: intravenous solution
Effects and side effects of esmolol (the active ingredient contained in Brevibloc) are usually brief and transient because of the relatively short half-life of esmolol (approximately 9 minutes).
Significant reductions of left and right ventricular ejection fractions, increases in pulmonary capillary wedge pressure, and decreases in cardiac output have been reported in patients with a mean left ventricular (LV) ejection fraction of 0.27. None of these changes were clinically significant, but the investigators advise cautious monitoring of the hemodynamic status in patients with LV dysfunction, especially at dosages greater than 200 mcg per kg per min.
Cardiovascular side effects are the most common. Symptomatic (diaphoresis or dizziness) and asymptomatic hypotension occur in up to 14% and 50% of patients, respectively. Hypotension is more likely with dosages greater than 200 mcg per kg per min. Peripheral ischemia, pallor, flushing, chest pain, syncope, bradycardia, pulmonary edema, and heart block have been reported in less than 1% of patients. Hemodynamic changes are reported in patients with left ventricular dysfunction.
Nervous system side effects include dizziness, weakness, somnolence or headache in 3% to 7% of patients. Paresthesias, anorexia, asthenia, lightheadedness, agitation and general irritability occur in less than 1% of patients. One fatal seizure associated with esmolol (the active ingredient contained in Brevibloc) is reported.
Gastrointestinal complaints are mainly limited to nausea in 6% of patients. Dyspepsia, general abdominal discomfort, dry mouth, and vomiting are reported in less than 1% of patients.
Respiratory system side effects including bronchospasm, dyspnea, wheezing nasal congestion, rhonchi, and rales have been reported in less than 1% of patients. As with other beta-adrenergic receptor antagonists, esmolol (the active ingredient contained in Brevibloc) should be given cautiously, if at all, to patients with a reactive airways disease.
Local intravenous site reactions including inflammation and induration have been reported (approximately 8%). Edema, erythema, skin discoloration, burning, thrombophlebitis, and local skin necrosis have been reported in less than 1% of patients.
