Lanoxin (Digoxin)

Digoxin blocks the Na⁺/K⁺‑ATPase pump on heart muscle cells, leading to higher intracellular sodium. This change reduces the sodium‑calcium exchanger activity, causing calcium buildup that strengthens heart contractions. Additionally, digoxin increases vagal tone, which slows conduction through the atrioventricular node and helps control abnormal heart rhythms.

The appropriate dose of Lanoxin is individualized by the prescribing clinician based on factors such as age, kidney function, electrolyte status, and concurrent medications. Dosage decisions are made after evaluating the patient’s clinical condition and may be adjusted during therapy.

Lanoxin is classified as pregnancy category C, meaning risk cannot be ruled out. It should only be used if the potential benefit justifies the potential risk to the fetus. Limited data are available for breastfeeding; the decision to continue therapy should be made by the healthcare provider after weighing benefits and risks.

To place an order, submit an enquiry on the Lanoxin product page at gnhindia.com, specifying the required quantity. GNH India works with hospitals, pharmacies, and procurement teams worldwide, verifies trade or institutional credentials, and then provides pricing, availability, shipping details (including any cold‑chain requirements), and necessary import documentation.

Unlike many anti‑arrhythmics that primarily block ion channels, digoxin exerts its effect by enhancing vagal tone and increasing myocardial contractility. This dual action makes it useful for both heart failure and rate control, whereas drugs such as beta‑blockers or calcium‑channel blockers mainly reduce heart rate without improving contractility.

Lanoxin tablets should be stored at temperatures below 25 °C. Keep them in the original container, protect from moisture and direct sunlight, and ensure the packaging remains tightly closed to maintain product stability.

Lanoxin is taken orally, usually with or without food, as directed by the prescriber. The tablet should be swallowed whole with a glass of water. Patients should follow the dosing schedule provided by their healthcare professional and not alter the regimen without medical advice.

The most serious risks include digoxin toxicity, which can manifest as severe arrhythmias, marked bradycardia, heart block, and life‑threatening ventricular tachycardia. Toxicity is more likely with renal impairment, electrolyte disturbances, or drug interactions that raise serum digoxin levels.

Lanoxin is contraindicated in patients with known hypersensitivity to digoxin or other cardiac glycosides, in those with ventricular fibrillation, and in individuals with severe uncontrolled electrolyte imbalances. Caution is also advised for patients with significant AV block without a pacemaker.
