Generic Cardarone Information

Introduction

Cardarone is a prescription medication classified under the cardiovascular group. Its active ingredient is amiodarone, a potent anti‑arrhythmic agent used to manage life‑threatening irregular heart rhythms. In Hong Kong, Cardarone is prescribed by cardiologists and electrophysiologists for patients whose arrhythmias are not adequately controlled by first‑line drugs. Amiodarone’s broad spectrum of activity makes it valuable for both ventricular and supraventricular tachyarrhythmias, and it is also employed off‑label for certain refractory atrial fibrillation cases.

What is Cardarone?

• Generic composition: Cardarone contains the same active compound, amiodarone, that is found in well‑known brand products such as Cordarone, Pacerone, and Nexterone.
• Classification: Class III anti‑arrhythmic (potassium channel blocker) with additional calcium‑channel‑blocking, β‑adrenergic‑blocking, and α‑adrenergic‑blocking properties.
• Development: Amiodarone was first synthesized in the 196s and approved worldwide for serious cardiac arrhythmias. Cardarone is marketed by a pharmaceutical company that supplies generic cardiovascular agents across Asia; the exact manufacturer can be confirmed on the product label.

Our online pharmacy offers Cardarone as a cost‑effective generic alternative to branded amiodarone products, providing the same therapeutic benefit at a lower price point.

How Cardarone Works

Amiodarone exerts its anti‑arrhythmic effect through multiple electrophysiological mechanisms:

• Potassium channel blockade prolongs phase 3 repolarisation, lengthening the action‑potential duration and the refractory period in cardiac myocytes.
• Sodium channel inhibition reduces rapid depolarisation, slowing impulse conduction.
• β‑adrenergic antagonism diminishes sympathetic stimulation of the heart, lowering heart rate and contractility.
• Calcium channel blockade contributes to decreased automaticity in atrial and ventricular tissue.

The combined actions produce a stabilized cardiac rhythm, suppressing abnormal automaticity and re‑entry circuits. Amiodarone has a long elimination half‑life (approximately 50 days), resulting in sustained therapeutic levels after loading, but also necessitating careful monitoring for cumulative toxicity.

Conditions Treated with Cardarone

• Ventricular tachycardia (VT) – sustained or non‑sustained VT that is refractory to other anti‑arrhythmics.
• Ventricular fibrillation (VF) – used in acute settings when electrical cardioversion is not immediately possible.
• Atrial fibrillation (AF) – especially persistent or long‑standing AF where rate and rhythm control are required.
• Atrial flutter – for rhythm conversion and maintenance.
• Supraventricular tachycardia (SVT) – when first‑line agents (e.g., adenosine, β‑blockers) are ineffective.

In Hong Kong, cardiovascular disease remains a leading cause of mortality, with arrhythmias contributing significantly to hospital admissions. The prevalence of AF increases with age, and the aging population in Hong Kong makes amiodarone‑based therapy a critical component of contemporary cardiology practice.

Patient Groups Most Likely to Benefit

• Patients with structural heart disease (e.g., post‑myocardial infarction scar, cardiomyopathy) who have documented VT or VF.
• Individuals with recurrent AF who have failed or are intolerant to first‑line agents such as flecainide or propafenone.
• Patients requiring long‑term rhythm control where the risk‑benefit profile of amiodarone is acceptable, particularly when catheter ablation is unavailable or contraindicated.
• Elderly patients who may not tolerate higher doses of other anti‑arrhythmics but can be monitored closely for side effects.

Contraindications or caution: severe sinus‑node dysfunction, severe hypothyroidism, high‑grade AV block without pacemaker support, and known hypersensitivity to iodine‑containing compounds.

Risks, Side Effects, and Interactions

Common

• Photosensitivity – skin may become more prone to sunburn; patients should use sunscreen.
• Taste disturbance – metallic or bitter taste, particularly after oral loading doses.
• Nausea, vomiting, abdominal discomfort – usually transient during the loading phase.
• Mild visual blur – often resolves without intervention.

Rare

• Thyroid dysfunction – both hypothyroidism and hyperthyroidism can emerge due to iodine content.
• Pulmonary toxicity – interstitial pneumonitis or fibrosis, more likely with prolonged high‑dose therapy.
• Hepatic enzyme elevation – monitoring of ALT/AST is recommended.
• Corneal micro‑deposits – may cause halos or blurred vision but are generally reversible.

Serious

• Life‑threatening arrhythmias – pro‑arrhythmic effects such as torsades de pointes, especially when combined with other QT‑prolonging drugs.
• Severe bradycardia – can precipitate syncope; may require temporary pacing.
• Pulmonary fibrosis – irreversible respiratory compromise requiring discontinuation and corticosteroid therapy.
• Severe hepatic injury – rare but may lead to liver failure.

Drug–Drug Interactions

• Warfarin – amiodarone potentiates anticoagulant effect; INR monitoring required.
• Statins (e.g., simvastatin, atorvastatin) – increased risk of myopathy; dose adjustments advisable.
• Digoxin – plasma levels rise; monitor for toxicity (nausea, visual changes).
• Other QT‑prolonging agents (e.g., quinidine, sotalol) – additive risk of torsades; avoid combination if possible.
• Cytochrome P450 inhibitors/inducers – amiodarone is metabolised by CYP3A4 and CYP2C8; concomitant use may alter drug levels.

Patients should provide a full medication list to their healthcare provider before initiating Cardarone.

Practical Use: Dosing, Missed Dose, Overdose

• Loading phase: 800 mg orally daily for 1 week, followed by 400 mg daily for the next 2 weeks, then a maintenance dose of 100–200 mg daily. Intravenous loading (150 mg over 10 min, then 1 mg/min for 6 h, then .5 mg/min) may be used in emergency settings.
• Maintenance: 100–200 mg once daily, adjusted to therapeutic response and plasma levels (if monitored).
• 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: Seek emergency medical care immediately. Symptoms may include severe bradycardia, hypotension, nausea, vomiting, and respiratory depression. Treatment is largely supportive; activated charcoal may be considered if ingestion is recent.

Precautions:

• Take with meals to reduce gastrointestinal irritation.
• Avoid grapefruit juice, which can inhibit CYP3A4 metabolism.
• Alcohol may exacerbate liver toxicity; limit consumption.
• Patients with impaired renal function require careful monitoring, although amiodarone is predominantly hepatically cleared.

FAQ

• Is Cardarone available in both brand‑name and generic forms in Hong Kong?
  Yes. The original brand-name versions such as Cordarone and Pacerone are marketed by multinational companies, while Cardarone is the locally available generic containing the same active compound, amiodarone.

• Does Cardarone require cold storage?
  No special refrigeration is needed. Store the tablets at room temperature, protected from excessive heat, moisture, and direct sunlight.

• What packaging does Cardarone come in when ordered online?
  Cards are supplied in sealed, tamper‑evident bottles containing 30, 60, or 90 tablets, depending on the selected quantity. Each bottle includes a printed patient information leaflet in English and Chinese.

• Can Cardarone be safely imported into Hong Kong for personal use?
  Personal import of prescription medicines is allowed only with a valid Hong Kong prescription. Our online pharmacy ensures compliance by requiring a professional evaluation before dispatch, aligning with local import regulations.

• Are there manufacturer warnings about Cardarone specific to Asian populations?
  Clinical data do not indicate ethnicity‑specific dosing changes. However, physicians may monitor thyroid and hepatic function more closely in populations with a higher prevalence of underlying thyroid disease.

• Does Cardarone have differences in formulation between regions (e.g., US vs EU vs Asia)?
  The core active ingredient, amiodarone hydrochloride, is consistent worldwide. Excipients such as lactose or microcrystalline cellulose may vary slightly to meet regional pharmacopeial standards, but they do not affect therapeutic efficacy.

• Can Cardarone be used in telemedicine‑based treatment plans?
  Yes, provided the telemedicine service includes a licensed clinician who can assess cardiac history, perform necessary ECG monitoring, and issue a valid prescription that meets Hong Kong legal standards.

• What is the typical time frame for blood‑level monitoring after starting Cardarone?
  Baseline liver, thyroid, and pulmonary function tests are recommended before therapy. Follow‑up testing is usually performed at 1 month, 3 months, and then every 6 months, or sooner if symptoms arise.

• Is Cardarone compatible with implantable cardioverter‑defibrillators (ICDs)?
  Amiodarone is often prescribed alongside ICDs to reduce shock burden. It does not interfere with device function, but clinicians program the device after initiating therapy to account for any changes in arrhythmia thresholds.

• How long does it take for Cardarone to reach therapeutic effect after the loading dose?
  Therapeutic plasma concentrations are usually achieved within 1–2 weeks of the loading regimen. Clinical improvement in rhythm control may be observed earlier, but full efficacy often requires several weeks of maintenance dosing.

• Can Cardarone be taken with dietary supplements such as calcium or iron?
  Calcium and iron supplements do not interact directly with amiodarone. However, they may affect absorption of other concurrent medications; therefore, maintain a gap of at least 2 hours between Cardarone and any other oral drugs to avoid potential interference.
