  • Avoid use in patients with minimally symptomatic or easily reversible AFIB/AFL.
Sotalol-based-on-HCl-xtal-3D-sf

How does this medicine work?[edit | edit source]

  • The hydrochloride salt form of sotalol, an ethanolamine derivative with class iii antiarrhythmic and antihypertensive properties.
  • Sotalol hydrochloride is a nonselective beta adrenergic receptor and potassium channel antagonist.
  • In the heart, this agent inhibits chronotropic and inotropic effects thereby slowing the heart rate and decreasing myocardial contractility.
  • This agent also reduces sinus rate, slows conduction in the atria and in the atrioventricular (av) node and increases the functional refractory period of the av node.
  • In the lungs, sotalol inhibits vasodilation and bronchodilation.
  • In addition, this agent inhibits renin release.

Who Should Not Use this medicine ?[edit | edit source]

This medicine cannot be used in patients with:

Recommended dosage: Adult Dose for Ventricular Arrhythmias:

  • The recommended initial dose is 80 mg twice daily.
  • This dose may be increased in increments of 80 mg per day every 3 days provided the QTc <500 msec.

Adult Dose for Prevention of Recurrence of AFIB/AFL:

  • The recommended initial dose is 80 mg twice daily.
  • This dose may be increased in increments of 80 mg per day every 3 days provided the QTc <500 msec.

For Children Aged About 2 Years and Older:

  • For initiation of treatment, 1.2 mg/kg three times a day (3.6 mg/kg total daily dose) is approximately equivalent to the initial 160 mg total daily dose for adults.
  • Subsequent titration to a maximum of 2.4 mg/kg three times a day can then occur.

For Children Aged About 2 Years or Younger:

  • The initial starting dose would be 0.8 mg/kg, administered three times daily.

Administration:

  • Sotalol comes as a tablet to take by mouth.
  • Sotalol (Betapace) is usually taken twice a day and sotalol (Betapace AF) is usually taken once or twice a day.
  • Take sotalol consistently, either with food or without food each time.
  • Sotalol controls your condition but does not cure it.
  • Continue to take sotalol even if you feel well.
  • Do not stop taking sotalol without talking to your doctor.
  • If sotalol is stopped suddenly, it may cause chest pain or heart attack.

What side effects can this medication cause?[edit | edit source]

The most common side effects of this medicine include:

What special precautions should I follow?[edit | edit source]

  • Sotalol can cause life-threatening ventricular tachycardia associated with QT interval prolongation. If the QT interval prolongs to 500 msec or greater, reduce the dose, lengthen the dosing interval, or discontinue the drug.
  • To minimize the risk of drug-induced arrhythmia, initiate or reinitiate oral sotalol in a facility that can provide cardiac resuscitation and continuous electrocardiographic monitoring.
  • if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking sotalol.
  • you should know that this drug may make you drowsy. Do not drive a car or operate machinery until you know how this drug affects you.
  • Advise patients to avoid taking sotalol hydrochloride/sotalol hydrochloride AF tablets within two hours of taking antacids that contain aluminum oxide or magnesium hydroxide.
  • Advise patients that they should not miss a dose, but if they do miss a dose they should not double the next dose to compensate for the missed dose: they should take the next dose at the regularly scheduled time.
  • Sotalol produces significant reductions in both systolic and diastolic blood pressures and may result in hypotension. Monitor hemodynamics in patients with marginal cardiac compensation.
  • New onset or worsening heart failure may occur during initiation or uptitration of sotalol because of its beta- blocking effects. Monitor for signs and symptoms of heart failure and discontinue treatment if symptoms occur.
  • Chronically administered beta-blocking therapy should not be routinely withdrawn prior to major surgery.
  • Avoid abrupt withdrawal of beta-blockade in patients with thyroid disease because it may lead to an exacerbation of symptoms of hyperthyroidism, including thyroid storm. Beta-blockade may mask certain clinical signs (for example, tachycardia) of hyperthyroidism.
  • Advise patients to contact their healthcare provider in the event of syncope, pre-syncopal symptoms or cardiac palpitations.
  • Advise patients to contact their healthcare provider in the event of conditions that could lead to electrolyte changes such as severe diarrhea, unusual sweating, vomiting, less appetite than normal, or excessive thirst.

What to do in case of emergency/overdose?[edit | edit source]

Symptoms of overdosage may include:

Management of overdosage:

  • If overdosage occurs, therapy with sotalol should be discontinued and the patient observed closely.
  • Because of the lack of protein binding, hemodialysis is useful for reducing sotalol plasma concentrations.
  • Patients should be carefully observed until QT intervals are normalized and the heart rate returns to levels >50 bpm.

In addition, if required, the following therapeutic measures are suggested:

Can this medicine be used in pregnancy?[edit | edit source]

  • Both the untreated underlying condition in pregnancy and the use of sotalol in pregnancy cause adverse outcomes to the mother and fetus/neonate.
