Lanoxin

Lanoxin (also known as Digoxin) is a cardiac glycoside that is commonly used in the treatment of various heart conditions, including atrial fibrillation, atrial flutter, and heart failure that cannot be controlled by other medication. It is derived from the leaves of a digitalis plant.

Mechanism of Action

Lanoxin works by inhibiting the sodium-potassium ATPase, leading to an increase in the amount of intracellular calcium. This, in turn, increases the force of contraction of the heart muscle, slows the heart rate, and helps to restore a regular, steady rhythm.

Side Effects

Common side effects of Lanoxin include nausea, vomiting, diarrhea, and dizziness. More serious side effects can include arrhythmia, hallucinations, and vision changes.

Interactions

Lanoxin can interact with a number of other medications, including calcium channel blockers, beta blockers, and some antibiotics. It is important to inform your healthcare provider of all medications you are currently taking to avoid potential interactions.

Dosage

The dosage of Lanoxin is based on the patient's age, weight, kidney function, and response to treatment. It is typically taken once daily, with or without food.

Precautions

Before taking Lanoxin, it is important to inform your healthcare provider if you have any history of kidney disease, thyroid disease, or certain types of heart rhythm problems.
