Adrebloc is a beta adrenergic blocker indicated for the short-term treatment of: Control of ventricular rate in supraventricular tachycardia including atrial fibrillation and atrial flutter and control of heart rate in noncompensatory sinus tachycardia. Control of perioperative tachycardia and hypertension.
Esmolol Hydrochloride is a beta-1 selective (cardioselective) adrenergic receptor blocking agent with rapid onset, a very short duration of action, and no significant intrinsic sympathomimetic or membrane stabilizing activity at therapeutic dosages. Its elimination half-life after intravenous infusion is approximately 9 minutes. Esmolol Hydrochloride inhibits the beta 1 receptors located chiefly in cardiac muscle, but this preferential effect is not absolute and at higher doses it begins to inhibit beta 2 receptors located chiefly in the bronchial and vascular musculature.
Administer intravenously. Titrate using ventricular rate or blood pressure at ≥4 minute intervals. Supraventricular tachycardia (SVT) or noncompensatory sinus tachycardia- Optional loading dose: 500 mcg per kg infused over one minute Then 50 mcg per kg per minute for the next 4 minutes Adjust dose as needed to a maximum of 200 mcg per kg per minute Additional loading doses may be administered Perioperative tachycardia and hypertension- Loading dose: 500 mcg per kg over 1 minute for gradual control (1 mg per kg over 30 seconds for immediate control). Than 50 mcg per kg per minute for gradual control (150 mcg per kg per minute for immediate control) adjusted to a maximum of 200 (tachycardia) or 300 (hypertension) mcg per kg per minute.

Most common adverse reactions (incidence> 10%) are symptomatic hypotension (hyperhidrosis, dizziness) and asymptomatic hypotension.
Severe sinus bradycardia Heart block greater than first degree Sick sinus syndrome Decompensated heart failure Cardiogenic shock Coadministration of IV cardiodepressant calcium-channel antagonists (e.g. verapamil) in close proximity to Esmolol hydrochloride Pulmonary hypertension Known hypersensitivity to esmolol
Digitalis glycosides: Risk of bradycardia Anticholinesterases: Prolongs neuromuscular blockade Antihypertensive agents: Risk of rebound hypertension Sympathomimetic drugs: Dose adjustment needed Vasoconstrictive and positive inotropic effect substances: Avoid concomitant use
Risk of hypotension, bradycardia, and cardiac failure: Reduce or discontinue use Risk of exacerbating reactive airway disease Diabetes mellitus: Increases the effect of hypoglycemic agents and masks hypoglycemic tachycardia Risk of unopposed alpha-agonism and severe hypertension in untreated pheochromocytoma Risk of myocardial ischemia when abruptly discontinued in patients with coronary artery disease
