  • Beta-Blockers, Nonselective

Nonselective beta-adrenergic blocking agent and class III antiarrhythmic

Indicated for treatment of life-threatening ventricular tachycardia; antiarrhythmic drugs may not enhance survival in patients with ventricular arrhythmias

Indicated for maintenance of normal sinus rhythm in patient with highly symptomatic atrial fibrillation/flutter (AFIB/AFL) who are currently in sinus rhythm

Indicated for the maintenance of normal sinus rhythm in patients with symptomatic atrial fibrillation or atrial flutter who are currently in sinus rhythm.

Sinus bradycardia (<50 bpm), sick sinus syndrome or second or third degree AV block without a pacemaker

Significant reductions of both systolic and diastolic blood pressure may occur; monitor hemodynamics in patients with marginal cardiac compensation

New onset or worsening heart failure may occur during initiation or uptitration of sotalol owing to its beta-blocking effects; monitor for signs and symptoms of heart failure and discontinue treatment if symptoms occur

Patients with bronchospastic diseases (eg, chronic bronchitis, emphysema) should not receive beta-blockers; if sotalol must be used, use smallest effective dose to minimize inhibition of bronchodilation produced by endogenous or exogenous catecholamine stimulation of beta2 receptors

May mask sign of hypoglycemia (ie, tachycardia)

Avoid abrupt withdrawal in patients with thyroid disease, as it may exacerbate symptoms of hyperthyroidism

While taking beta-blockers, patients with a history of anaphylactic reaction to allergens may have a more severe reaction on repeated challenge, either accidental, diagnostic or therapeutic; may be unresponsive to usual epinephrine doses

Chronically administered beta-blocking therapy should not be routinely withdrawn before major surgery; however, the impaired ability of the heart to respond to reflex adrenergic stimuli may augment the risks of general anesthesia and surgical procedures

This drug should not be administered to a pregnant woman unless clinical benefit outweighs potential risk to fetus

The excretion of ibutilide into breast milk has not been studied; accordingly, breastfeeding should be discouraged during therapy with this drug
