Lanoxin (Digoxin)

Digoxin inhibits the Na⁺/K⁺‑ATPase pump on cardiac cells, leading to increased intracellular sodium. This change reduces the activity of the sodium‑calcium exchanger, causing calcium to accumulate inside the cell, which strengthens heart muscle contractions. At the same time, digoxin enhances vagal tone, slowing atrioventricular nodal conduction and helping control heart rate.

The appropriate dose of Lanoxin is individualized by the prescribing clinician based on factors such as the patient’s age, renal function, electrolyte status, and therapeutic response. Dosage adjustments are guided by clinical assessment and, when necessary, serum digoxin concentration monitoring to maintain safe and effective drug levels.

Data on digoxin use in pregnancy are limited, and the drug is generally avoided unless the potential benefit outweighs the risk to the fetus. Digoxin does pass into breast milk in small amounts; therefore, caution is advised for nursing mothers, and a healthcare professional should evaluate the risk‑benefit profile before continuation.

To request Lanoxin, submit an enquiry on the 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.

Lanoxin (digoxin) offers a unique positive inotropic effect and rate‑control capability, which differs from beta‑blockers, ACE inhibitors, or ARBs that primarily reduce cardiac workload and remodel the heart. While digoxin can improve symptoms and exercise tolerance, it does not replace guideline‑directed therapies and is often used as an adjunct, especially when rate control is needed.

Store Lanoxin tablets at ambient temperature, preferably below 25 °C, in the original container to protect them from moisture and direct sunlight. Keep the medication out of reach of children and avoid exposure to extreme heat or humidity, which could affect tablet integrity.

Lanoxin is taken orally, usually as a tablet swallowed whole with a glass of water. It may be taken with or without food, but consistency with meals helps maintain stable absorption. Patients should follow the prescribing clinician’s instructions regarding timing and any required dose adjustments.

The most critical risks involve digoxin toxicity, which can manifest as life‑threatening arrhythmias (e.g., ventricular tachycardia), severe bradycardia, heart block, and marked electrolyte disturbances such as hyperkalemia. Visual changes like yellow‑green halos and gastrointestinal symptoms may also signal toxicity and require immediate medical evaluation.

Lanoxin is contraindicated in patients with known hypersensitivity to digoxin, ventricular fibrillation, or advanced atrioventricular block without a pacemaker. Caution is also advised for individuals with severe renal impairment, uncontrolled electrolyte imbalances, or those taking interacting medications that could precipitate toxicity.
