What is Lanoxin

Lanoxin is the brand name for a drug containing the active ingredient digoxin, which is used to treat certain heart conditions. The drug is effective in treating heart failure and controlling the heart rate in atrial fibrillation. It is important for maintaining heart function and improving the quality of life of patients with chronic heart disease.

Lanoxin: Classification, uses and medical indications

Lanoxin, whose active ingredient is digoxin, belongs to a class of drugs known as cardiac glycosides. This drug has a complex effect on the cardiovascular system, which can be divided into several key aspects:

Effects on cardiomyocytes: Lanoxin increases the strength of heart contractions through direct effects on cardiomyocytes, the muscle cells of the heart. It increases the concentration of calcium ions inside the cells, which leads to increased contractility (positive inotropic effect).

Effect on the nervous system: The drug modulates the activity of the parasympathetic nervous system, which contributes to slowing down the heart rate. This is achieved by increasing the sensitivity of cardiac nerve endings to acetylcholine, a mediator of the parasympathetic nervous system.

Decreased conduction: Lanoxin slows the conduction of electrical impulses through the atrioventricular node (AV node) of the heart. This is especially important in the treatment of arrhythmias because slowing conduction helps control the heart rate.

Effects on the kidneys: Through its effects on the kidneys, digoxin helps to reduce the volume of circulating blood and decrease the workload of the heart, thereby alleviating symptoms of heart failure.

Through these mechanisms, Lanoxin helps to improve blood flow and relieve symptoms in patients with heart failure, as well as control heart rhythm in arrhythmias. This leads to improved exercise tolerance and improved quality of life in patients.


Heart failure

Initial Dosage: For adults, the starting dose of Lanoxin is usually 0.75 to 1.25 mg, divided into several doses over 24 hours. This loading dose allows rapid attainment of therapeutic digoxin blood concentrations.

Maintenance dose: After the loading dose, the maintenance dose is usually 0.125 to 0.25 mg daily. Dosage may be adjusted depending on the patient's clinical response and digoxin blood levels.

Arrhythmias and atrial fibrillation

Loading dosage: Same as for heart failure.

Maintenance dose: Also similar, ranging from 0.125 to 0.25 mg daily. When treating arrhythmias, special attention is paid to monitoring heart rhythm and regular measurement of digoxin levels.

Careful monitoring of digoxin levels in the blood is vital because the therapeutic and toxic levels of this drug are very close. The normal therapeutic range for Lanoxin is 0.5 to 2.0 ng/mL. Periodic testing helps to avoid toxicity, especially in high-risk patients.

Lanoxin dosage should be closely monitored by a physician, especially in the presence of risk factors such as age, comorbidities, and current drug therapy. Regular visits to the doctor and monitoring of the health condition provide the greatest safety and effectiveness of digoxin treatment.


Known hypersensitivity to digoxin or other components of the drug: Patients with a history of allergic reactions to digoxin should not take Lanoxin.

Certain types of arrhythmias: The drug is contraindicated for certain types of arrhythmias, including ventricular fibrillation and ventricular tachycardia, as it may aggravate these conditions.

Electrolyte balance disorders: Low levels of potassium or magnesium in the blood increase the risk of digoxin toxicity, so levels of these electrolytes should be monitored before and during treatment.

Sinus node weakness syndrome and AV blockade: Patients with these conditions should only be prescribed Lanoxin under strict medical supervision, unless there is an established pacemaker.

Side Effects

Gastrointestinal symptoms: Nausea, vomiting, diarrhea, and abdominal pain are among the most common side effects and usually occur during the initial phase of treatment.

CNS disorders: Dizziness, fatigue, confusion and even hallucinations may occur, especially in elderly patients.

Cardiovascular reactions: Include bradycardia, tachycardia, and other arrhythmias. The severity of these effects requires immediate attention.

Visual disturbances: Changes in color perception, blurred vision, or the appearance of "flies" in front of the eyes may be a sign of high digoxin concentrations in the blood.

Lanoxin near me: Availability and cost

The availability and cost of Lanoxin can vary by country and region. In most countries, including the United States and European Union countries, the drug is available only with a doctor's prescription. However, in some countries, such as Mexico, it is possible to buy Lanoxin without a prescription.

Buying lanoxin online can be a convenient way to obtain medication for those who live in remote or hard-to-reach areas. Many online pharmacies offer direct home delivery, making the buying process more comfortable. However, it is important to choose reliable and licensed online pharmacies to avoid counterfeit and low-quality products.

Lanoxin prices can vary greatly depending on the dosage and form of release. Lanoxin 25 mg price can vary by region and pharmacy. For example, in Mexico, where laws are more flexible, the Lanoxin 0.25 price is usually more budget-friendly than in other countries and allows you to buy Lanoxin without a prescription. However, it is advisable to consult a doctor before starting any medication to avoid possible complications and side effects.

Lanoxin is a life-saving drug for many patients, and its availability and cost play a key role in ensuring continuity of treatment. It is important to research different purchasing and cost options, whether at local pharmacies or online, to find the most appropriate and cost-effective option. Keep in mind that the safety and efficacy of treatment should remain a priority when selecting a source of medication.

Interaction of Lanoxin with other medicines

Understanding interactions with other medications is critical to ensuring the safety and effectiveness of treatment.

Beta-blockers and calcium channel blockers (e.g., verapamil, diltiazem): These drugs may increase the effect of digoxin on heart rate, increasing the risk of bradycardia. They may also increase the inotropic effect of digoxin, requiring dosage adjustment.

Diuretics (especially loop diuretics such as furosemide): Although diuretics are often used in combination with digoxin to treat heart failure, they may contribute to a decrease in blood potassium levels, increasing the risk of digoxin toxicity. It is important to monitor electrolyte levels with this combination.

P-glycoprotein inhibitors and inducers: Some drugs, including verapamil, amylodipine, and some antiepileptic drugs, may alter digoxin clearance, increasing or decreasing its concentration in the blood. This may require an adjustment of the digoxin dose.

Antibiotics (e.g., erythromycin, tetracycline): Some antibiotics may increase digoxin levels in the blood, increasing its effects and the risk of adverse reactions.

Antacids containing aluminum and magnesium: These agents may reduce the absorption of digoxin in the intestine, reducing its effectiveness. It is recommended that antacids be taken 2 hours before or after taking Lanoxin.

Antifungal agents (e.g., itraconazole): May increase plasma digoxin levels, which requires monitoring and possible dose adjustment.

Fiber foods: High-fiber diets may reduce digoxin absorption. It is important to maintain regularity in food and drug intake to prevent fluctuations in absorption.

When prescribing Lanoxin, it is important to consider any potential interactions with other medications the patient is taking. Regular monitoring of digoxin levels in the blood, observation of the patient's condition, and adequate dose adjustments ensure optimal treatment efficacy and minimize risks.

Lanoxin is an important medication for many people with heart disease, but its use requires strict adherence to medical guidelines. It is important for patients to regularly consult with their doctor and report any changes in their condition to optimize treatment customization and avoid potential risks.
