Concomitant admin w/ vasoconstrictive and inotropic agents (e.g. epinephrine, norepinephrine, dopamine), IV Ca channel blockers (e.g. verapamil).

Precautions

Patients w/ inadequate cardiac function, well-compensated heart failure, bronchospastic disease, myasthenia gravis, conduction disorder, peripheral vascular disease. May mask signs and symptoms of hypoglycaemia and hyperthyroidism. Avoid abrupt withdrawal as it may precipate thyroid storm or MI, and may exacerbate angina and ventricular arrhythmias. Renal impairment. Pregnancy and lactation. Monitoring Parameters Monitor BP. Perform continuous ECG, monitor respiratory rate, serum K esp in patients w/ renal impairment.

Pregnancy-Lactation

Interactions

May increase serum digoxin levels. Additive effects w/ catecholamine-depleting drugs (e.g. reserpine). May prolong neuromuscular blockade of succinylcholine. May increase serum levels w/ morphine or warfarin. May decrease hypotensive effects w/ NSAIDs. Potentially Fatal: May lead to fatal cardiac arrest w/ IV Ca channel blockers (e.g. verapamil). Increased risk of reducing cardiac contractility in presence of high systemic vascular resistance w/ vasoconstrictive or inotropic drugs (e.g. dopamine, norepinephrine, epinephrine).

Adverse Effects

Side effects of Esmolol : >10% Hypotension, asymptomatic (25-38%) Hypotension, symptomatic (12%) 1-10% Injection site pain (8%) Nausea (7%) Dizziness (3%) Somnolence (3%) Agitation (2%) Confusion(2%) Headache (2%) Fatigue (1%) Vomiting (1%) <1% Bradycardia Chest pain Anxiety Anorexi Depression Abdominal discomfort Constipation Dry mouth Dyspepsia Taste perversion Bronchospasm Dyspnea Nasal congestion Wheezing

Mechanism of Action

Esmolol is a short-acting cardioselective agent, which competitively blocks beta1-adrenergic receptor while having little effect on the beta2-adrenergic receptors of bronchial and vascular smooth muscle. At high doses, selectivity usually diminishes, and the drug will competitively inhibit beta1- and beta2-adrenergic receptors.
