Video Summary:
This is video on digoxin mechanism of action.
Notes from the video.
- Digoxin is a cardiac glycoside
- It is used in heart failure
- It inhibits Na-K ATPase pump and thereby increases intracellular Ca after sequence of events. Increased Ca helps cardiac myocyte contract better.
- Digoxin and K competes with other for same binding site on Na-K ATPase.
- In case of hypokalaemia there are chances of digoxin toxicity and in hyperkalemia digoxin effect may reduce.
