3. How Does Lanoxin Work?

Lanoxin, also known as digoxin, belongs to a class of medications called cardiac glycosides. It works by increasing the force of contraction of the heart and slowing down the heart rate, thus helping the heart to pump more efficiently. Digoxin acts on the sodium-potassium ATPase pump in the cell membrane of heart muscle cells, inhibiting the pump and increasing the levels of calcium inside the cells. This results in increased contractility and decreased conduction velocity throughout the heart.

Specifically, Lanoxin works by:

Inhibiting the Sodium-Potassium ATPase Pump

The Sodium-Potassium ATPase pump is responsible for maintaining the balance of sodium and potassium ions inside and outside the heart muscle cells. Digoxin binds to the ATPase enzyme of the pump, preventing it from pumping out excess sodium ions. This leads to an increased concentration of sodium inside the cell, which in turn inhibits the activity of the sodium-calcium exchanger. This causes an increase in the intracellular concentration of calcium ions, which ultimately enhances the force of contraction of the heart.

Slowing Down the Heart Rate

Lanoxin also acts on the electrical conduction system of the heart to slow down the heart rate. It acts on the atrioventricular (AV) node, which is responsible for transmitting electrical signals from the atria to the ventricles. By slowing down conduction through the AV node, Lanoxin helps to separate the electrical activity of the atria and ventricles, leading to a more coordinated and efficient heart rhythm.

Lanoxin is primarily used to treat various heart conditions, such as heart failure and certain types of arrhythmias (abnormal heart rhythms). It helps to improve symptoms such as shortness of breath, fatigue, and fluid retention. However, it is important to note that Lanoxin may not be suitable for everyone and should only be used under the guidance of a healthcare professional.
