Description
About
The human heart’s pumping is a uniquely orchestrated mechanism based on synchronized beats and signal conduction of impulses, operating atria, ventricles, and the valves to allow continuous “beating” of the heart, thus permitting life. Any disturbance in this rhythm arrangement can lead to irregular heartbeat, at times getting very quick, manifested as palpitations. This condition is called Atrial Fibrillation, a chronic heart condition affecting the atria. Lanoxin 0.5mg Injection 2 ml belongs to a class of drugs called Antiarrhythmics/ cardiac glycosides, used to treat disturbance in heart rhythm (fibrillation), heart failure, etc. Lanoxin 0.5mg Injection 2 ml is chemically composed of Digoxin, available as oral tablets and IV solution to be taken strictly under a doctor’s prescription.
Digoxin contained in Lanoxin 0.5mg Injection 2 ml shows its clinical effects via 2 basic mechanisms, Positive tropism (heart contraction) by inhibiting Na+/K+-ATPase causes an increase in calcium levels in heart cells, and secondly Negative chronotropic effect (reduced heart rate) through activation of Parasympathetic nervous system, causing a decrease in AV node conduction slowing down the heart rate. It improves the overall compromised function of the heart. Lanoxin 0.5mg Injection 2 ml is usually taken for long periods, strictly follow your doctor’s advice.
Lanoxin 0.5mg Injection 2 ml is available as oral tablets on prescription to be swallowed by mouth with a glass of water once a day or as advised by the doctor. Do not crush or chew the tablet.
