Indication |
For the treatment and management of Congestive cardiac insufficiency, arrhythmias and heart failure. |
Pharmacodynamics |
Deslanoside is a cardiac glycoside used to treat congestive
heart failure and supraventricular arrhythmias due to reentry
mechanisms, and to control ventricular rate in the treatment of chronic
atrial fibrillation. |
Mechanism of action |
Deslanoside inhibits the Na-K-ATPase membrane pump, resulting in
an increase in intracellular sodium and calcium concentrations.
Increased intracellular concentrations of calcium may promote activation
of contractile proteins (e.g., actin, myosin). Deslanoside also acts on
the electrical activity of the heart, increasing the slope of phase 4
depolarization, shortening the action potential duration, and decreasing
the maximal diastolic potential. |
