Generic Betapace

What it is used for

1 INDICATIONS AND USAGE Sotalol hydrochloride tablets are an antiarrhythmic indicated for: the treatment of life-threatening ventricular arrhythmias ( 1.1 ) the maintenance of normal sinus rhythm in patients with atrial fibrillation or flutter (AFIB/AFL) ( 1.2 ) Limitations of Use Sotalol hydrochloride tablets have not been shown to enhance survival in patients with life-threatening ventricular arrhythmias ( 1.1 ) Avoid use in patients with minimally symptomatic or easily reversible AFIB/AFL ( 1.2 ) 1.1 Life-Threatening Ventricular Arrhythmias Sotalol hydrochloride tablets are indicated for the treatment of documented, life-threatening ventricular arrhythmias, such as sustained ventricular tachycardia (VT) . Limitation of Use Sotalol hydrochloride tablets have not been shown to enhance survival in patients with life-threatening ventricular arrhythmias. 1.2 Delay in Recurrence of Atrial Fibrillation/Atrial Flutter (AFIB/AFL) Sotalol hydrochloride tablets are indicated for the maintenance of normal sinus rhythm (delay in time to recurrence of AFIB/AFL) in patients with highly symptomatic AFIB/AFL who are currently in sinus rhythm. Limitation of Use: Because sotalol hydrochloride tabl

How it is taken

2 DOSAGE AND ADMINISTRATION Sotalol hydrochloride tablets: Initial dosage in adults is 80 mg twice daily. Increase the dose as needed in increments of 80 mg/day, every 3 days to a maximum 320 mg total daily dose ( 2.2 ) Pediatrics: Dosage depends on age ( 2.4 ) 2.1 General Safety Measures for Initiation of Oral Sotalol Therapy Withdraw other antiarrhythmic therapy before starting sotalol hydrochloride tablets and monitor for a minimum of 2 to 3 plasma half-lives prior to initiating sotalol hydrochloride tablets therapy if the patient's clinical condition permits [see Drug Interactions ( 7 )] . Hospitalize patients being initiated or re-initiated on sotalol for at least 3 days or until steady-state drug levels are achieved in a facility that can provide cardiac resuscitation and continuous electrocardiographic monitoring. Initiate oral sotalol therapy in the presence of personnel trained in the management of serious arrhythmias. Perform a baseline ECG to determine the QT interval and measure and normalize serum potassium and magnesium levels before initiating therapy. Measure serum creatinine and calculate an estimated creatinine clearance in order to establish the appropriate dosin

Warnings

5 WARNINGS AND PRECAUTIONS QT prolongation, bradycardia, AV block, hypotension, worsening heart failure: Reduce dose or discontinue ( 5.1 ) Acute exacerbation of coronary artery disease upon cessation of therapy: Do not abruptly discontinue ( 5.5 ) Correct any electrolyte disturbances ( 5.1 ) Diabetes: May mask symptoms of hypoglycemia and alter glucose levels; monitor ( 5.7 ) 5.1 QT Prolongation and Proarrhythmia Sotalol hydrochloride can cause serious and potentially fatal ventricular arrhythmias such as sustained VT/VF, primarily Torsade de Pointes (TdP) type ventricular tachycardia, a polymorphic ventricular tachycardia associated with QT interval prolongation. Factors such as reduced creatinine clearance, female sex, higher doses, reduced heart rate, and history of sustained VT/VF or heart failure increase the risk of TdP. The risk of TdP can be reduced by adjustment of the sotalol dose according to creatinine clearance and by monitoring the ECG for excessive increases in the QT interval [see Dosage and Administration ( 2.1 )] . Correct hypokalemia or hypomagnesemia prior to initiating sotalol hydrochloride, as these conditions can exaggerate the degree of QT prolongation, and
