Study Notes
Cardiac Glycosides
- Digoxin (Lanoxin) is the prototype drug of cardiac glycosides
- Mechanism of action of cardiac glycosides is to increase the force of the heartbeat and decrease the heart rate
- The primary effect of cardiac glycosides is to regulate the heart's rhythm and contractions
This quiz covers cardiac glycosides, focusing on the prototype drug digoxin and its mechanism of action in increasing heart force and slowing heart rate.
