Generic Amiodarone Information

Introduction

Amiodarone is a potent anti‑arrhythmic medication belonging to the cardiovascular group of drugs. It is prescribed to restore and maintain normal heart rhythm in patients with serious ventricular and supraventricular tachyarrhythmias. In Hong Kong, amiodarone is available through licensed pharmacies and, increasingly, via online channels that meet local regulatory requirements. The active compound is amiodarone, and its clinical use reflects extensive evidence from international trials and local cardiology practice.

What is Amiodarone?

Amiodarone is a synthetic iodine‑containing benzofuran derivative that functions as a class III anti‑arrhythmic agent. It was first synthesized in the 196s and marketed by several pharmaceutical companies under brand names such as Cordarone® and Pacerone®.

Amiodarone is the generic version of Cordarone®, containing the same active compound amiodarone. Our online pharmacy provides this generic alternative as a cost‑effective treatment option.

The medication is supplied as oral tablets (typically 100 mg or 200 mg) and as intravenous infusion for acute settings. It is classified under the Anatomical Therapeutic Chemical (ATC) code C01BD01.

How Amiodarone Works

Amiodarone exerts its anti‑arrhythmic effect through multiple ion‑channel interactions:

• Potassium channel blockade prolongs phase 3 repolarisation, lengthening the action‑potential duration and refractory period (class III effect).
• Sodium channel inhibition slows phase  depolarisation, reducing conduction velocity (class I effect).
• Beta‑adrenergic blockade diminishes sympathetic stimulation of the myocardium (class II effect).
• Calcium channel inhibition modestly reduces intracellular calcium influx (class IV effect).

These combined actions stabilize cardiac electrical activity, suppress ectopic pacemaker activity, and prevent re‑entry circuits. Oral amiodarone has a slow onset (2–4 weeks to reach steady‑state plasma levels) due to its high lipophilicity and extensive tissue binding. The terminal elimination half‑life ranges from 20 days to several months, accounting for prolonged therapeutic and adverse effects.

Conditions Treated with Amiodarone

• Ventricular tachycardia (VT) and ventricular fibrillation (VF) – especially when other agents are ineffective or contraindicated.
• Atrial fibrillation (AF) and atrial flutter – used for rhythm control in persistent or symptomatic cases.
• Supraventricular tachycardia (SVT) – when catheter ablation or other drugs are unsuitable.
• Life‑threatening ventricular arrhythmias in myocardial infarction – as rescue therapy pending definitive management.

In Hong Kong, the prevalence of AF is estimated at 1–2 % of the adult population, and ventricular arrhythmias contribute significantly to sudden cardiac death. Amiodarone remains a guideline‑endorsed option when rapid rate control fails or when patients have structural heart disease that limits the use of other anti‑arrhythmics.

Patient Groups Most Likely to Benefit

• Patients with structural heart disease (e.g., ischemic cardiomyopathy, hypertrophic cardiomyopathy) where class IA/IC agents pose higher pro‑arrhythmic risk.
• Elderly individuals (>65 years) with persistent AF who require rhythm control and tolerate the drug’s long half‑life.
• Post‑myocardial infarction patients with recurrent VT/VF despite optimal revascularisation.
• Patients unsuitable for catheter ablation due to comorbidities or limited access to electrophysiology services.

Amiodarone is not first‑line for uncomplicated paroxysmal AF or for patients with mild disease where beta‑blockers or calcium‑channel blockers suffice. Caution is advised in patients with severe hepatic impairment, thyroid disease, or pre‑existing pulmonary fibrosis.

Risks, Side Effects, and Interactions

Common

• Digestive disturbances – nausea, vomiting, constipation, loss of appetite.
• Photosensitivity – skin becomes more prone to sunburn; sunscreen recommended.
• Transient visual halos – usually resolve after dose adjustment.

Rare

• Blue‑gray skin discoloration – due to melanin deposition; often reversible after discontinuation.
• Thyroid dysfunction – both hypothyroidism and hyperthyroidism may emerge after months of therapy.
• Peripheral neuropathy – tingling or numbness in extremities, typically dose‑related.

Serious

• Pulmonary toxicity – interstitial pneumonitis or fibrosis; presents with dyspnoea, dry cough, and infiltrates on imaging. Immediate drug cessation and corticosteroid therapy may be required.
• Severe hepatotoxicity – marked elevation of transaminases, bilirubin, or cholestasis.
• Life‑threatening arrhythmias – pro‑arrhythmic effects, especially torsades de pointes, in the setting of electrolyte imbalance.
• Corneal micro‑deposits – visual disturbances; regular ophthalmologic review advised.

Drug–Drug Interactions

• Warfarin – amiodarone inhibits CYP2C9, increasing INR; dose reduction of warfarin is often needed.
• Statins (e.g., simvastatin, atorvastatin) – increased risk of myopathy; consider dose reduction or alternative statin.
• Digoxin – plasma levels rise; monitor for digoxin toxicity.
• Sotalol, quinidine, procainamide – additive QT‑prolongation; ECG monitoring essential.
• Macrolide antibiotics (e.g., erythromycin) and azole antifungals (e.g., ketoconazole) – further CYP3A4 inhibition, raising amiodarone concentrations.

Patients should disclose all current medications, including over‑the‑counter supplements, to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Loading phase (oral): 800–1,200 mg/day divided into 2–3 doses for 1–2 weeks, then taper to a maintenance dose of 100–200 mg/day.
• Intravenous loading: 150 mg over 10 minutes, followed by 1 mg/min for 6 hours, then .5 mg/min for 18 hours (adjusted for weight and renal function).
• Maintenance: 100–200 mg once daily; dose individualized based on rhythm control and side‑effect profile.

Missed dose: Take the missed tablet as soon as remembered unless the next scheduled dose is within 12 hours; in that case, skip the missed dose and resume the regular schedule. Do not double‑dose.

Overdose: Acute oral overdose (>5 g) may cause severe hypotension, bradyarrhythmia, and respiratory depression. Seek emergency medical care; treatment is supportive with cardiac monitoring, possible vasopressor support, and atropine for bradycardia. Activated charcoal may be considered if presentation is within one hour.

Precautions: Take tablets with food to reduce GI upset. Avoid excessive alcohol, which can exacerbate hepatic toxicity. Regular laboratory monitoring (thyroid, liver, pulmonary function, ECG) is mandatory, typically every 3–6 months.

FAQ

• Is amiodarone available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand‑name products, such as Cordarone®, are marketed alongside generic formulations that contain the identical active compound amiodarone. Generic versions are typically less expensive while providing the same therapeutic effect.

• How should amiodarone tablets be stored at home?
  Store tablets in a dry place at a temperature between 15 °C and 30 °C, protected from light, moisture, and direct heat. Do not keep them in bathrooms or near kitchen stoves.

• Can I take amiodarone with other anti‑arrhythmic drugs?
  Co‑administration is possible but requires careful ECG monitoring and dose adjustments. Combining amiodarone with other class III agents can markedly prolong the QT interval and increase the risk of torsades de pointes.

• What are the most common signs of amiodarone‑induced lung toxicity?
  Early symptoms include dry cough, shortness of breath, and low‑grade fever. Imaging may reveal diffuse interstitial infiltrates. Prompt evaluation and discontinuation of the drug are essential to prevent irreversible fibrosis.

• Does amiodarone affect blood tests for cholesterol or liver enzymes?
  Amiodarone can cause modest elevations in hepatic transaminases (ALT, AST) and may interfere with lipid panel results. Routine monitoring every 3–6 months helps distinguish drug‑related changes from underlying disease.

• Is it safe for pregnant women to use amiodarone?
  Amiodarone is classified as a Category D medication (risk to fetus) due to potential thyroid and fetal growth effects. It should be avoided unless the maternal benefit clearly outweighs fetal risk, and only under specialist supervision.

• Can I travel internationally while taking amiodarone?
  Yes, but carry a copy of your prescription, a medication list, and a letter from your physician. Be aware that the drug can cause photosensitivity; use sunscreen and protective clothing when exposed to strong sunlight.

• Are there differences in amiodarone formulation between regions (e.g., US vs. EU vs. Asia)?
  The active ingredient and core pharmacokinetic properties are consistent worldwide. Tablet excipients (inactive ingredients) may vary slightly, potentially affecting tolerability in patients with specific allergies.

• What monitoring schedule is recommended for a new patient starting amiodarone?
  Baseline assessment should include ECG, liver function tests, thyroid function tests (TSH, free T4), chest radiograph, and pulmonary function tests if there is a history of lung disease. Follow‑up tests are typically performed at 1 month, then every 3 months for the first year, and semi‑annually thereafter.

• Can I obtain amiodarone without a local prescription through your online service?
  Our online pharmacy arranges a tele‑prescription from a licensed physician after reviewing your medical information. This satisfies Hong Kong regulatory requirements, allowing you to receive the medication without obtaining a separate paper prescription.

• Does amiodarone interact with herbal supplements such as St John’s wort?
  St John’s wort induces CYP3A4, which may lower amiodarone plasma concentrations and reduce efficacy. Patients should inform their healthcare provider of any complementary medicines they are taking.

• What should I do if I experience visual disturbances while on amiodarone?
  Report symptoms such as halos, blurred vision, or decreased visual acuity to your cardiologist promptly. An ophthalmology referral is often required to assess corneal deposits and rule out optic neuropathy.
