Lenoxin® Mite

Digoxin, the active ingredient in Lenoxin® Mite, is a cardiac glycoside presented as an oral dosage form (strength not disclosed) for oral use. It is used to improve cardiac contractility in heart failure and to control ventricular rate in atrial fibrillation, primarily in adult patients. GNH USA supplies Lenoxin® Mite as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Digoxin acts on the cardiac conduction system and myocardial contractility, making it useful in several cardiovascular conditions.

- Heart failure: increases cardiac output and reduces symptoms of congestion. - Atrial fibrillation (rate control): slows ventricular response to improve heart rate control. - Supraventricular tachycardia: may help control ventricular rate when other measures are insufficient.

Adverse reactions to digoxin vary in frequency and severity.

Common Side Effects: - Nausea: gastrointestinal upset that may be mild to moderate. - Fatigue: generalized tiredness often reported by patients. - Visual disturbances: blurred vision or color perception changes. - Headache: occasional mild headache.

Serious or Rare Side Effects: - Cardiac arrhythmias: potentially life‑threatening rhythm disturbances. - Severe bradycardia: markedly slowed heart rate requiring medical attention. - Hyperkalemia: elevated serum potassium that can exacerbate toxicity. - Allergic skin reactions: rash or urticaria indicating hypersensitivity.

When prescribing digoxin, clinicians should consider several safety factors.

- Renal function: adjust dose in patients with impaired clearance. - Electrolyte balance: monitor potassium and magnesium levels to avoid toxicity. - Thyroid disease: use caution in hyperthyroid patients as they may be more sensitive. - Drug level monitoring: obtain serum digoxin concentrations to stay within therapeutic range. - Pregnancy and lactation: evaluate risk versus benefit before use. - Store at below 25°C: keep in the original container, protect from moisture.

Digoxin interacts with several medicines that can alter its plasma concentration or cardiac effects.

Major Interactions (Avoid): - Amiodarone: markedly increases digoxin levels. - Quinidine: raises digoxin concentrations and risk of toxicity. - Verapamil: enhances digoxin exposure and may cause bradycardia. - Spironolactone: can potentiate digoxin toxicity.

Moderate Interactions (Monitor Closely): - Loop and thiazide diuretics: affect electrolyte balance, influencing digoxin safety. - Beta‑blockers: additive effect on heart rate and AV nodal conduction. - Macrolide antibiotics (e.g., erythromycin): may modestly increase digoxin levels.
