Generic Lanoxin Information

Introduction

Lanoxin is a cardiovascular medication containing the cardiac glycoside digoxin. It is primarily prescribed in the United Kingdom for the long‑term management of chronic heart failure and for rate control in atrial fibrillation or atrial flutter. By improving the efficiency of cardiac muscle contraction and modulating autonomic tone, Lanoxin helps relieve symptoms such as breathlessness, fatigue and palpitations, and reduces hospital admissions for heart‑related events. The drug is manufactured by several licensed pharmaceutical companies and is classified within the cardiac‑glycoside group of cardiovascular agents.

What is Lanoxin?

Lanoxin is a tablet formulation that delivers a fixed dose of digoxin, the active cardiac glycoside. Digoxin has been in clinical use for more than a century and was originally isolated from the foxglove plant (Digitalis lanata). Modern production of Lanoxin involves synthetic preparation of digoxin followed by strict quality control to ensure uniform potency and purity. The product is marketed in the United Kingdom by multiple authorised distributors, each adhering to the Medicines and Healthcare products Regulatory Agency (MHRA) standards for safety and efficacy.

How Lanoxin Works

Digoxin exerts its therapeutic effect through three inter‑related mechanisms:

• Inhibition of the Na⁺/K⁺‑ATPase pump – By blocking this membrane pump in cardiac myocytes, intracellular sodium rises. The elevated sodium reduces the activity of the Na⁺/Ca²⁺ exchanger, causing calcium to accumulate inside the cell.
• Increased intracellular calcium – The excess calcium is stored in the sarcoplasmic reticulum and released during each heartbeat, strengthening myocardial contraction (positive inotropic effect). This improves stroke volume and cardiac output in patients with systolic dysfunction.
• Enhanced vagal tone – Digoxin stimulates the vagus nerve, slowing conduction through the atrioventricular (AV) node. The resultant negative dromotropic effect reduces ventricular rate in atrial fibrillation or flutter without markedly lowering blood pressure.

Pharmacokinetic considerations are crucial because digoxin has a narrow therapeutic window. After oral administration, absorption is rapid (bio‑availability ≈ 70‑80 %). The drug distributes preferentially to cardiac tissue, kidneys and skeletal muscle. A single dose has a terminal half‑life of 36‑48 hours in patients with normal renal function; clearance declines markedly in renal impairment, necessitating dose adjustment. Steady‑state concentrations are usually achieved after 5‑7 days of regular dosing.

Conditions Treated with Lanoxin

• Chronic heart failure (NYHA class II–IV) – Digoxin improves symptom burden, reduces hospitalisation rates, and may modestly increase survival when combined with guideline‑directed therapy (ACE inhibitors, β‑blockers, mineral‑ocorticoid antagonists). In the United Kingdom, over 900 000 adults live with heart failure, making effective outpatient management a public‑health priority.
• Atrial fibrillation or atrial flutter with rapid ventricular response – Rate control is achieved without the need for additional β‑blockers in some patients, especially those intolerant to negative‑inotropic agents. Approximately 1.3 % of the UK adult population experiences atrial fibrillation, and many require a safe, oral rate‑controlling medication.
• Occasional off‑label use for supraventricular tachycardia – In specialist settings, digoxin may be employed when other anti‑arrhythmic drugs are contraindicated, although evidence is limited.

Who is Lanoxin For?

Lanoxin benefits a specific subset of cardiovascular patients:

• Adults with systolic heart failure who remain symptomatic despite optimal use of ACE inhibitors/ARNI, β‑blockers and diuretics. It is particularly useful when the ejection fraction is ≤ 35 % and the patient experiences exertional dyspnoea or peripheral oedema.
• Patients with atrial fibrillation in whom ventricular rate control is required but β‑blockers or non‑DHP calcium‑channel blockers are unsuitable (e.g., severe asthma, brady‑cardic tendency, or hypotension).
• Elderly individuals who prefer once‑daily oral therapy and have reliable adherence. Dose titration is often more gradual in this group to avoid toxicity.
• Individuals with preserved renal function (creatinine clearance > 50 mL/min) because digoxin is primarily renally cleared. Patients with chronic kidney disease may still use Lanoxin, but at reduced doses and with close monitoring.

Lanoxin is not appropriate for:

• Patients with uncontrolled hyper‑kalaemia or severe electrolyte disturbances, as these conditions predispose to digoxin toxicity.
• Individuals with known hypersensitivity to digoxin or any excipients in the tablet formulation.
• Pregnant or breastfeeding women, where teratogenic risk and infant exposure outweigh potential benefits.
• Patients with acute myocardial infarction requiring inotropic support beyond the modest effect of digoxin, where agents such as dobutamine are preferred.

Risks, Side Effects, and Interactions

Common

• Nausea, vomiting or diarrhoea
• Fatigue or weakness
• Blurred or yellow‑green visual disturbances (chromatopsia)
• Anorexia or loss of appetite

Rare

• Cardiac arrhythmias (e.g., premature ventricular contractions, atrial tachycardia)
• Severe bradycardia leading to syncope
• Hyper‑kalaemia unrelated to renal dysfunction (due to digoxin‑induced shift of potassium)

Serious

• Life‑threatening ventricular tachyarrhythmias or ventricular fibrillation
• High‑grade AV block requiring pacemaker implantation
• Digoxin toxicity with multi‑organ involvement (neurological confusion, hallucinatory visual changes, profound electrolyte imbalance)

Clinically Relevant Drug–Drug Interactions

• Amiodarone, quinidine, verapamil, diltiazem – inhibit digoxin metabolism and increase serum concentrations; dose reduction of Lanoxin is usually required.
• Loop and thiazide diuretics – promote potassium loss, enhancing the risk of digoxin‑related arrhythmias.
• Macrolide antibiotics (e.g., erythromycin, clarithromycin) – raise digoxin levels by reducing gastrointestinal clearance.
• Antidepressants (e.g., sertraline, fluoxetine) – may modestly increase digoxin exposure.
• St. John’s wort – induces P‑glycoprotein and may lower digoxin concentrations, reducing efficacy.
• Thyroid hormone replacement – excess thyroid hormone increases digoxin clearance, potentially necessitating a higher dose.

Patients should inform their clinician of all prescription, over‑the‑counter and herbal products they are taking.

Practical Use: Dosing, Missed Dose, Overdose

• Standard dosing for chronic heart failure – .125 mg (.125 mg tablet) once daily, titrated after 5–7 days to a maximum of .25 mg daily based on serum digoxin concentration (.5–.9 ng/mL) and clinical response.
• Standard dosing for atrial fibrillation – .25 mg once daily; a lower starting dose of .125 mg may be used in frail or renally impaired patients.
• Renal adjustment – When creatinine clearance falls below 50 mL/min, initiate therapy at .125 mg daily and consider extending the dosing interval (e.g., every 48 hours) after evaluating serum levels.

Missed dose:
If a dose is remembered within 12 hours, take it immediately. If more than 12 hours have passed, skip the missed tablet and resume the regular schedule; do not double‑dose.

Overdose:
Symptoms may include severe nausea, vomiting, visual changes, and arrhythmias. Immediate action includes:

• Calling emergency services (999 in the UK).
• Providing activated charcoal if ingestion was recent (within 1 hour).
• Monitoring cardiac rhythm continuously.
• Administration of digoxin‑specific antibody fragments (e.g., Digibind) in hospital settings, especially when serum digoxin exceeds 2.5 ng/mL or life‑threatening arrhythmias develop.

Practical precautions:

• Avoid large amounts of caffeine or alcohol, which can exacerbate palpitations.
• Maintain regular monitoring of serum digoxin, electrolytes (especially potassium and magnesium), and renal function.
• Do not change dietary potassium intake abruptly without medical guidance.
• Store tablets at room temperature, protected from moisture and direct sunlight.

FAQ

• Can Lanoxin be taken with other heart medications such as beta‑blockers?
  Yes, Lanoxin is often prescribed alongside beta‑blockers when additional rate control or inotropic support is required. However, clinicians must monitor for additive bradycardia and adjust doses accordingly.

• What is the appearance of Lanoxin tablets and how can I identify them?
  Lanoxin tablets are round, film‑coated, and typically embossed with “.125” or “.25” to indicate the strength in milligrams. The colour may vary between manufacturers but is usually white or off‑white with a scored line for half‑tablet dosing.

*Does Lanoxin require refrigeration during storage or shipping?**
No, Lanoxin is stable at room temperature (15‑30 °C). It should be kept away from excess heat, moisture, and direct sunlight, but refrigeration is not necessary.

• Are there any dietary restrictions while using Lanoxin?
  While no specific foods are prohibited, patients should avoid sudden changes in potassium intake, as both hypo‑ and hyper‑kalaemia can predispose to toxicity. Moderate potassium‑rich foods (bananas, oranges) are acceptable when serum levels are within the normal range.

• Can Lanoxin affect laboratory tests, such as urine drug screens or cardiac biomarkers?
  Digoxin does not typically cause false‑positive results on standard drug screens, but it can interfere with certain immunoassays for thyroid hormones and may alter serum potassium readings if toxicity is present. Laboratories should be informed of digoxin therapy when interpreting ambiguous results.

• Is it legal to import Lanoxin for personal use into the UK?
  Personal import of a prescription‑only medication like Lanoxin is permitted under UK law when the supply is for a legitimate private use and the total quantity does not exceed a three‑month supply. Importation must comply with MHRA guidance and customs regulations.

• What is the historical significance of digoxin in cardiology?
  Digoxin, derived from foxglove, was first used in the 18th century and became the cornerstone of heart‑failure therapy before the advent of newer agents. Its long‑standing clinical experience provides a robust safety record, even though modern guidelines now reserve it for specific indications.

• How does the effectiveness of Lanoxin compare with newer heart‑failure drugs such as sacubitril/valsartan?
  Contemporary heart‑failure regimens prioritize neprilysin inhibitors, ACE inhibitors, β‑blockers and mineral‑ocorticoid antagonists. Digoxin adds modest mortality benefit and improves symptoms, particularly for patients with persistent fatigue or exercise intolerance despite optimal therapy.

• Are there any known differences between Lanoxin formulations sold in Europe versus those manufactured in the United States or Asia?
  European formulations must meet the European Pharmacopoeia standards for purity, which are equivalent to US and Asian pharmacopeial requirements. However, excipient composition (e.g., fillers, colourants) may differ, potentially influencing tolerability in patients with hypersensitivity.

• What should I do if I experience visual disturbances such as a yellow‑green halo while taking Lanoxin?
  Visual changes are a hallmark of digoxin toxicity and warrant immediate medical evaluation. Patients should discontinue the medication and seek urgent care, where serum digoxin levels and electrolyte status will be assessed.

• Does Lanoxin have any impact on pregnancy outcomes, and is it safe for breastfeeding mothers?
  Digoxin crosses the placenta and is excreted in breast milk. Because potential fetal cardiac effects and infant toxicity cannot be ruled out, Lanoxin is generally avoided during pregnancy and lactation unless the benefit clearly outweighs the risk.

Glossary

Na⁺/K⁺‑ATPase

An essential membrane enzyme that pumps sodium out of cells and potassium into cells, maintaining electrochemical gradients. Digoxin’s inhibition of this pump leads to increased intracellular calcium and stronger heart contractions.

Therapeutic Window

The range of drug concentrations in the blood that provides optimal efficacy while minimizing toxicity. For digoxin, the window is narrow (≈ .5–.9 ng/mL), requiring regular monitoring.

Bioavailability

The proportion of an administered dose that reaches systemic circulation unchanged. Lanoxin’s oral bioavailability is about 70‑80 %, meaning most of the tablet is absorbed.

Half‑Life

The time required for the plasma concentration of a drug to decrease by 50 %. Digoxin’s half‑life is 36‑48 hours in individuals with normal renal function.
