Generic Sotalol Information

Introduction

Sotalol is a prescription medication used primarily to manage abnormal heart rhythms (arrhythmias). In Hong Kong, it is classified under the General health medication group and is available as a generic product that contains the active compound sotalol. The drug is also marketed under well‑known brand names such as Betapace and Betapace SR. It is prescribed for patients who require rhythm control of atrial fibrillation, atrial flutter, or ventricular tachycardia, and it is sometimes employed off‑label for other cardiac conditions after careful clinical evaluation.

What is Sotalol?

Sotalol is a synthetic compound that belongs to the class III anti‑arrhythmic agents and also possesses non‑selective β‑adrenergic blocking activity. It was first developed by G.D. Searle & Co. in the late 197s and later commercialized by Pfizer under the brand name Betapace. The generic version, marketed by numerous licensed distributors, contains the same active ingredient, sotalol, and offers a cost‑effective alternative for patients in Hong Kong.

Sotalol is the generic version of Betapace, containing the same active compound sotalol. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

How Sotalol Works

Sotalol exerts its therapeutic effect through two complementary mechanisms:

• β‑Blockade (Class II activity).
  By blocking β₁ and β₂ adrenergic receptors, sotalol reduces sympathetic stimulation of the heart. This leads to a slower heart rate, lowered myocardial contractility, and decreased conduction velocity through the atrioventricular (AV) node, which helps prevent rapid ventricular response during atrial arrhythmias.

• Potassium channel blockade (Class III activity).
  Sotalol prolongs the cardiac action potential by inhibiting the rapid component of the delayed rectifier potassium current (I_Kr). The resulting lengthening of the repolarisation phase increases the effective refractory period of myocardial cells, thereby suppressing re‑entrant circuits that cause tachyarrhythmias.

The combination of β‑blockade and delayed repolarisation provides both rate‑control and rhythm‑control benefits. After oral administration, sotalol is rapidly absorbed, reaching peak plasma concentrations within 2–4 hours. The drug has a plasma elimination half‑life of approximately 12 hours in individuals with normal renal function, and it is predominantly cleared unchanged by the kidneys.

Conditions Treated with Sotalol

• Atrial fibrillation (AF) and atrial flutter.
  Sotalol is approved for maintaining sinus rhythm after successful cardioversion of AF or flutter. In Hong Kong, AF prevalence increases with age, affecting an estimated 1–2 % of adults over 65, making rhythm‑control strategies clinically important.

• Ventricular tachycardia (VT).
  For patients with sustained monomorphic VT who have structural heart disease or idiopathic VT, sotalol can suppress ventricular ectopy and reduce the frequency of episodes.

• Post‑cardioversion maintenance.
  After electrical or pharmacological cardioversion, sotalol helps prevent early recurrence of arrhythmia, decreasing the need for repeat procedures.

• Off‑label uses (physician discretion).
  Some clinicians employ sotalol for supraventricular tachycardia (SVT) or for prophylaxis in patients with congenital long‑QT syndrome, though these indications require individualized risk assessment.

Who is Sotalol For?

• Patients with recent cardioversion for AF or flutter who need long‑term rhythm maintenance and have preserved left‑ventricular function.
• Individuals with documented ventricular tachycardia where catheter ablation is not feasible or as adjunct therapy after ablation.
• Adults with normal or mildly impaired renal function (creatinine clearance ≥ 60 mL/min) because sotalol is renally cleared; dose adjustments are required for reduced clearance.
• People without severe sinus node dysfunction or high‑grade AV block, as β‑blockade can exacerbate bradyarrhythmias.

Contra‑indications and cautionary scenarios

• Severe heart failure (NYHA class III/IV) or recent myocardial infarction.
• Significant renal impairment (creatinine clearance < 30 mL/min).
• Congenital long‑QT syndrome without close electrophysiological monitoring.
• Concomitant use of other class III anti‑arrhythmics or drugs that markedly prolong the QT interval.

Patients meeting these criteria should undergo baseline ECG, renal function tests, and electrolyte assessment before initiating therapy.

Risks, Side Effects, and Interactions

Common

• Fatigue or drowsiness.
• Dizziness, especially upon standing (orthostatic hypotension).
• Nausea or mild gastrointestinal upset.
• Bradycardia (slow heart rate).

Rare

• Mild to moderate QT‑interval prolongation on ECG without symptomatic arrhythmia.
• Visual disturbances (e.g., blurred vision).
• Skin rash or pruritus.

Serious

• Torsades de pointes – a potentially life‑threatening polymorphic ventricular tachycardia triggered by excessive QT prolongation.
• Severe bradyarrhythmia requiring pacemaker implantation.
• Heart block (second‑degree or third‑degree AV block).
• Pulmonary edema in patients with underlying heart failure.

Drug–drug interactions

• Other QT‑prolonging agents (e.g., quinidine, amiodarone, certain antibiotics, antipsychotics) – additive risk of torsades.
• Potassium‑sparing diuretics (e.g., spironolactone) or digitalis – may enhance pro‑arrhythmic potential.
• Non‑selective β‑blockers – additive β‑blockade can cause marked bradycardia or hypotension.
• Renal‑clearing drugs (e.g., NSAIDs, certain antivirals) – may impair sotalol elimination, raising plasma levels.

Patients should disclose all medications, supplements, and herbal products to their healthcare provider before initiating sotalol.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing (adults).

  • Initial dose for atrial fibrillation: 80 mg twice daily.
  • For ventricular tachycardia: may start at 80 mg twice daily and titrate up to 160 mg twice daily based on ECG monitoring and renal function.
  • Dose adjustments: Reduce by 50 % if creatinine clearance is 30–60 mL/min; avoid use if < 30 mL/min.

• Administration.

  • Take tablets with or without food, at the same times each day to maintain steady plasma levels.
  • Swallow whole; do not split or crush extended‑release formulations.

• Missed dose.

  • If a dose is missed by less than 6 hours, take it as soon as remembered.
  • If more than 6 hours have passed, skip the missed dose and resume the regular schedule. Do not double‑dose.

• Overdose.

  • Symptoms may include severe bradycardia, hypotension, syncope, or arrhythmias such as torsades.
  • Immediate medical attention is required. Activated charcoal may be considered if presentation is within one hour of ingestion.
  • Treatment is primarily supportive: intravenous fluids, atropine for bradycardia, and magnesium sulfate for torsades.

• Precautions.

  • Avoid excessive alcohol, which can worsen hypotension and arrhythmia risk.
  • Maintain adequate potassium and magnesium levels; low electrolytes heighten QT prolongation risk.
  • Regular follow‑up ECGs (baseline, after dose adjustments, and periodically thereafter) are essential.

• What packaging does Sotalol come in when ordered online?
  It is supplied in blister packs or high‑density polyethylene bottles, each labeled with strength, lot number, and expiration date. Our online pharmacy includes a secondary discreet envelope for privacy.

• Can Sotalol be safely imported into Hong Kong for personal use?
  Personal import of a 30‑day supply of prescription medicines is permitted under Hong Kong’s Import and Export Ordinance, provided the medication is for personal use and declared appropriately. Our service assists with the required documentation.

• Are there specific warnings for Asian populations taking Sotalol?
  Pharmacogenomic data suggest that some East Asian patients may exhibit slightly higher plasma concentrations due to lower average body weight and renal clearance variations. Dose titration should be performed cautiously, with close ECG monitoring.

• How does the formulation of Sotalol differ between regions (e.g., US vs EU vs Asia)?
  The active ingredient is identical worldwide. In the US, tablets are usually 40 mg or 80 mg immediate‑release. European and Asian markets commonly offer 80 mg immediate‑release and 120 mg extended‑release formulations. Inactive excipients may vary, but therapeutic efficacy remains the same.

• What should I do if I need to travel abroad with Sotalol?
  Keep the medication in its original labeled container, carry a copy of the prescription or a physician’s letter, and retain it in your carry‑on luggage. Check the destination country’s regulations for personal import of prescription drugs.

• Does Sotalol interact with over‑the‑counter antihistamines?
  Most first‑generation antihistamines (e.g., diphenhydramine) have mild anticholinergic effects and do not significantly affect sotalol. However, some antihistamines can modestly prolong the QT interval; concurrent use should be discussed with a healthcare professional.

• Can Sotalol affect drug testing for employment or sports?
  Sotalol is not a controlled substance and is not screened for in standard drug‑testing panels. However, some occupational health programs may request a medication list; provide documentation if required.

• What clinical trials established the efficacy of Sotalol?
  The pivotal “BETAPACE I” and “BETAPACE II” trials demonstrated that sotalol reduced recurrence of atrial fibrillation after cardioversion compared with placebo, with a statistically significant improvement in sinus‑rhythm maintenance over a 6‑month follow‑up period.

• How long does it take for Sotalol to reach steady‑state concentration?
  Steady‑state is typically achieved after 3 to 5 half‑lives, equating to 36–60 hours of consistent twice‑daily dosing in patients with normal renal function.

• Is there a difference in side‑effect profile between immediate‑release and extended‑release Sotalol?
  Both formulations share the same adverse‑event spectrum because the active compound is identical. Extended‑release tablets may produce a smoother plasma‑level curve, potentially reducing peaks that could cause transient dizziness, but clinical data show comparable overall safety.

Glossary

β‑Blocker

A class of medication that blocks β‑adrenergic receptors, decreasing heart rate and contractility, and reducing the effects of adrenaline on the cardiovascular system.

QT Interval

A measurement on an ECG representing the time for ventricular depolarisation and repolarisation; prolongation can predispose to torsades de pointes, a dangerous arrhythmia.

Effective Refractory Period (ERP)

The interval after an action potential during which cardiac cells cannot be re‑excited; lengthening the ERP helps prevent re‑entrant tachyarrhythmias.

Renal Clearance

The volume of plasma cleared of a drug by the kidneys per unit time; for sotalol, renal clearance is the primary elimination pathway.
