Renal impairment
-
Ventricular arrhythmia (PO)
- CrCl >60 mL/min: Give q12hr
- CrCl 30-59 mL/min: Give q24hr
- CrCl 10-29 mL/min: Give q36-48hr
- CrCl <10 mL/min: Individualize dose
-
Atrial fibrillation/flutter (PO)
- CrCl >60 mL/min: Give q12hr
- CrCl 40-59 mL/min: Give q24hr
- CrCl <40 mL/min: Contraindicated
Dosing Considerations
Monitoring before initiating or re-initiating
- Perform baseline ECG to determine QT interval and measure and normalize serum potassium and magnesium levels before initiating therapy
- Measure serum creatinine and calculate estimated CrCl to establish appropriate dosing interval (if CrCl ≤60 mL/min dosing interval adjustment necessary)
- Continue ECG monitoring with each uptitration in dose, until steady state reached
- Determine QTc 2-4 hr after every dose; proarrhythmic event may occur after initiation of therapy and with each upward dosage adjustment
Limitations of use
- AFIB/AFL: Because therapy with sotalol can cause life-threatening ventricular arrhythmias, reserve use for patients in whom AFIB/AFL is highly symptomatic; patients with paroxysmal AFIB that is easily reversed (by Valsalva maneuver, for example) should usually not be treated

Arrhythmias
Indications
- 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
2 years or older
- Normal renal function: 30 mg/m2 PO TID initially (90 mg/m2 total daily dose) is approximately equivalent to initial 160 mg total daily dose for adults
- Subsequent titration to maximum 60 mg/m2 TID (approximately equivalent to the 320 mg total daily dose for adults) can then occur
- Guide titration by clinical response, heart rate and QTc, with increased dosing preferably carried out in-hospital
- Allow at least 36 hr between dose increments to attain steady-state plasma concentrations of drug in patients with age-adjusted normal renal function
<2 years
- Pediatric dosage should be reduced by a factor that depends heavily upon age
- Use graph in prescribing information where age in months is plotted on a logarithmic scale; see manufacturer's package insert for details
-
Examples
- Child aged 20 months: Dosing suggested for children with normal renal function aged ≥2, which is about 30 mg should be multiplied by about 0.97, which is the age factor (30 X 0.97) for a dose of 29.1 mg/m2
- Child aged 1 week: Initial starting dose (30 mg) should be multiplied by age factor 0.3; the starting dose would be (30 X 0.3) for a dose of 9 mg/m2

Warnings
Black Box Warnings
Minimize risk of drug-induced arrhythmia by initiating or uptitrating IV or PO sotalol in a facility that can provide continuous ECG monitoring and cardiac resuscitation
Calculate CrCl before initiating sotalol therapy; adjust dosing interval based on creatinine clearance
Sotalol has proarrhythmic effects and can cause life-threatening ventricular tachycardia associated with QT interval prolongation; do not initiate therapy if baseline QTc is >450 msec; if QT interval prolongs to ≥500 msec, dose must be reduced, duration of infusion prolonged or drug discontinued
Contraindications
Sinus bradycardia (<50 bpm), sick sinus syndrome or second or third degree AV block without a pacemaker
Congenital or acquired long QT syndromes, QT interval >450 ms
Cardiogenic shock, decompensated heart failure
Serum potassium <4 mEq/L
Bronchial asthma or related bronchospastic conditions
Known hypersensitivity to sotalol
If treating AFIB/AFL
- Baseline QT interval >450 ms
- CrCl <40 mL/min
Cautions
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
Abrupt discontinuation
- Abrupt discontinuation of beta-blockers may exacerbate angina and MI may occur; when discontinuing chronically administered sotalol (particularly in patients with ischemic heart disease), gradually reduce dose over 1-2 weeks is possible
- If angina markedly worsens or acute coronary ischemia develops, treat appropriately and consider use of alternative beta-blocker; warn patients not to interrupt therapy without their physician’s advice; because coronary artery disease is common, but maybe unrecognized, the abrupt discontinuation of sotalol may unmask latent coronary insufficiency
Proarrhythmia
- Can cause serious ventricular arrhythmias, primarily Torsade de Pointes (TdP) type ventricular tachycardia, a polymorphic ventricular tachycardia associated with QTc prolongation
- QTc prolongation is directly related to sotalol serum concentration
- Factors such as reduced creatinine clearance, gender (female) and higher dose, bradycardia, history of sustained VT/VF, atrial fibrillation with sinus node dysfunction, heart failure increase the risk of TdP
- TdP risk can be reduced by dose adjustment according to CrCl and by ECG monitoring for excessive QTc increases
- Correct hypokalemia or hypomagnesemia before initiating and avoid with other drugs known to prolong QT
Bradycardia/heart block/sick sinus syndrome
- Sinus bradycardia (HR <50 bpm) may occur
- Contraindicated in patients with sick sinus syndrome because it may cause sinus bradycardia, sinus pauses or sinus arrest
Drug interaction overview
Digoxin: Proarrhythmic events were more common in sotalol treated patients also receiving digoxin
Calcium channel blockers: Expected to have additive effects on atrioventricular conduction or ventricular function; monitor for bradycardia and hypotension
Digitalis glycosides, diltiazem, verapamil, and beta-blockers slow atrioventricular conduction and decrease heart rate; concomitant use with negative chronotropes can increase risk of bradycardia or hypotension
Catecholamine-depleting drugs: May produce excessive reduction of resting sympathetic nervous tone; monitor for bradycardia and hypotension
Insulin and oral antidiabetics: Hyperglycemia may occur; adjust dose of diabetes therapies if needed
Clonidine: Coadministration may increase risk of bradycardia; because beta-blockers may potentiate rebound hypertension sometimes observed after clonidine discontinuation, withdraw sotalol several days before the gradual withdrawal of clonidine to reduce the risk of rebound hypertension
Antacids: Avoid oral sotalol within 2 hr of aluminum oxide- and/or magnesium hydroxide-containing antacids
-
Antiarrhythmics and other QT prolonging drugs
- Coadministration with other drugs that prolong QT interval (eg, phenothiazines, tricyclic antidepressants, certain oral macrolides, certain quinolone antibiotics) may increase risk of life-threatening arrhythmias
- Discontinue Class I or Class III antiarrhythmic agents for at least three half-lives prior to dosing with sotalol; Class Ia antiarrhythmic drugs (eg, disopyramide, quinidine, procainamide) and other Class III drugs (eg, amiodarone) are not recommended as concomitant therapy
- Limited experience with concomitant use of Class Ib or Ic antiarrhythmics
- Additive Class II effects anticipated with concomitant use of other beta-blocking agents
Pregnancy & Lactation
Pregnancy
Both the untreated underlying condition in pregnancy and the use of sotalol in pregnancy cause adverse outcomes to the mother and fetus/neonate
Clinical considerations
- Incidence of VT increases and may be more symptomatic during pregnancy
- Most tachycardia episodes are initiated by ectopic beats and arrhythmia episodes may, therefore, increase during pregnancy
- Breakthrough arrhythmias may also occur during pregnancy, as therapeutic treatment levels may be difficult to maintain due to the increased volume of distribution and increased drug metabolism inherent in the pregnant state
-
Fetal/neonatal adverse effects
- Crosses placenta and is found in amniotic fluid
- Observational studies showed growth restriction, transient fetal bradycardia, hyperbilirubinemia, hypoglycemia, uterine contractions, and possible intrauterine death with exposure during pregnancy
- Sotalol may elicit a greater effect on QT prolongation in immature hearts than in adult hearts, and therefore, conveys an increased risk of serious fetal arrhythmia and/or possible intrauterine death
- Monitor newborns for symptoms of beta blockade
-
Labor or delivery
- Generally, risk of arrhythmias increases during the labor and delivery process; therefore, considering sotalol’s proarrhythmia potential, monitor patients continuously during labor and delivery
Animal studies
- Reproduction studies in rats, early resorptions were increased at 15 times the maximum recommended human dose (MRHD)
- In rabbits, an increase in fetal death was observed at 2 times the MRHD administered as single dose
- Sotalol did not reveal any teratogenic potential in rats or rabbits at 15 and 2 times the MRHD respectively
Infertility
- Beta blockers (including sotalol) may cause erectile dysfunction
Lactation
Sotalol present in human milk in high levels
Owing to the potential of serious adverse effects in breastfed children and the high level of sotalol in breast milk, advise women not to breastfeed during treatment
Estimated daily infant dose of sotalol received from breastmilk is 0.8-3.4 mg/kg, estimated at 22-25.5% of the maternal weight-adjusted dosage of sotalol
The amount of the drug in breast milk is similar to the neonatal therapeutic dosage; therefore, there is potential for bradycardia and other symptoms of beta blockade such as dry mouth, skin or eyes, diarrhea or constipation in breastfed infants
Data are not available regarding effects on milk production
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology

SOTALOL - ORAL
(SO-tuh-lol)
COMMON BRAND NAME(S): Betapace, Betapace AF
WARNING: Sotalol should be used only in certain patients. Before taking sotalol, discuss the risks and benefits of treatment with your doctor. Although sotalol is effective for treating certain types of fast/irregular heartbeats, it can rarely cause a new serious abnormal heart rhythm (QT prolongation in the EKG). This problem can lead to a new type of abnormal (possibly fatal) heartbeat (torsade de pointes). If this new serious heart rhythm occurs, it is usually when sotalol treatment is first started or when the dose is increased. To reduce the risk of this side effect, you should begin sotalol treatment in a hospital so your doctor can monitor your heart rhythm for several days and treat the problems if they occur. Patients usually start with a low dose of sotalol. Your doctor will then slowly increase your dose depending on how you respond to the medication and how well your kidneys work. If you respond well to this medication, during this time in the hospital your doctor can determine the right dose of sotalol for you.Some sotalol products are used to treat certain types of fast/irregular heartbeats (atrial fibrillation/flutter). These products come with additional written information from the manufacturer for patients with atrial fibrillation/flutter. If you have these conditions, read the provided information carefully. Do not switch brands of sotalol without checking with your doctor.Do not stop taking this medication without consulting your doctor. Some conditions may become worse when you suddenly stop this drug. Some people who have suddenly stopped taking similar drugs have had chest pain, heart attack, and irregular heartbeat. If your doctor decides you should no longer use this drug, your doctor may direct you to gradually decrease your dose over 1 to 2 weeks.When gradually stopping this medication, it is recommended that you temporarily limit physical activity to decrease strain on the heart. Get medical help right away if you develop: chest pain/tightness/pressure, chest pain spreading to the jaw/neck/arm, unusual sweating, trouble breathing, fast/irregular heartbeat.
USES: This medication is used to treat a serious (possibly life-threatening) type of fast heartbeat called sustained ventricular tachycardia. It is also used to treat certain fast/irregular heartbeats (atrial fibrillation/flutter) in patients with severe symptoms such as weakness and shortness of breath. Sotalol helps to lessen these symptoms. It slows the heart rate and helps the heart to beat more normally and regularly. This medication is both a beta blocker and an anti-arrhythmic.
HOW TO USE: See also Warning section.Read the Patient Information Leaflet if available from your pharmacist before you start using sotalol and each time you get a refill. If you have any questions, ask your doctor or pharmacist.Take this medication by mouth as directed by your doctor, usually 1 to 3 to times a day. You may take it with or without food, but it is important to choose one way and take it the same way with each dose.If you are using the liquid form of this medication, carefully measure the dose using a special measuring device/spoon. Do not use a household spoon because you may not get the correct dose.Dosage is based on your medical condition and response to treatment. In children, dosage is also based on age and body size.Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time(s) each day.If you use antacids containing aluminum or magnesium, do not take them at the same time as sotalol. These antacids can bind to sotalol and decrease its absorption and effectiveness. Separate doses of these antacids and sotalol by at least 2 hours to reduce this interaction.Do not take more of this drug than prescribed because you may increase your risk of side effects, including a new serious abnormal heartbeat. Do not take less of this medication or skip doses unless directed by your doctor. Your fast/irregular heartbeat is more likely to return if you do not take sotalol properly. Also, do not run out of this medication. Order your refills several days early to avoid running out of pills.Tell your doctor if your condition does not improve or if it worsens.
SIDE EFFECTS: See also Warning section.Tiredness, slow heartbeat, and dizziness may occur. Less common side effects include headache, diarrhea, and decreased sexual ability. If any of these effects last or get worse, tell your doctor or pharmacist promptly.To lower your risk of dizziness and lightheadedness, get up slowly when rising from a sitting or lying position.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: new or worsening symptoms of heart failure (such as shortness of breath, swelling ankles/feet, unusual tiredness, unusual/sudden weight gain).Get medical help right away if you have any very serious side effects, including: severe dizziness, fainting, sudden change in heartbeat (unusually faster/slower/more irregular), chest/jaw/left arm pain.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.
PRECAUTIONS: See also Warning section.Before taking sotalol, tell your doctor or pharmacist if you are allergic to it; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: certain heart rhythm problems (such as a slow heartbeat, sick sinus syndrome, second- or third-degree atrioventricular block unless you have a heart pacemaker), kidney problems, heart problems (such as heart failure, recent heart attack), breathing problems (such as asthma, chronic bronchitis, emphysema), overactive thyroid disease (hyperthyroidism), serious allergic reactions needing treatment with epinephrine.Sotalol may cause a condition that affects the heart rhythm (QT prolongation in the EKG). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using sotalol, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions: certain heart problems (QT prolongation in the EKG, history of torsade de pointes), family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death).Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills"), if you are unable to eat or drink fluids as you normally would, or if you have conditions such as severe/prolonged sweating, diarrhea, or vomiting. Talk to your doctor about using sotalol safely.This drug may make you dizzy. Alcohol or marijuana (cannabis) can make you more dizzy.
