Medicine Description lanoxin 0.5mg
Lanoxin ampoules is a medication that contains digoxin, which functions by inhibiting the sodium-potassium ATPase pump in cardiac myocytes. This inhibition leads to an increase in intracellular sodium levels, which subsequently enhances calcium influx through the sodium-calcium exchange mechanism. This results in improved myocardial contractility, or positive inotropic effect, allowing the heart to pump blood more effectively. Additionally, digoxin exerts a parasympathomimetic effect on the heart, decreasing heart rate and prolonging the refractory period of the atrioventricular (AV) node. This dual action of enhancing contractility while controlling heart rate makes it particularly beneficial in managing heart failure and certain arrhythmias, thus improving patient outcomes and quality of life.
