Digoxin Nursing Considerations - NurseStudy.Net
Mechanism of action: Digoxin inhibits the sodium-potassium ATPase pump, leading to increased intracellular calcium. This results in increased cardiac contractility (positive inotropic effect) and decreased conduction through the AV node (negative chronotropic effect).
Digoxin - StatPearls - NCBI Bookshelf - National Center for ...
2023年1月19日 · Digoxin has 2 principal mechanisms of action, which are selectively employed depending on the indication: Positive ionotropic: It increases the force of contraction of the heart by reversibly inhibiting the activity of the myocardial sodium=potassium adenosinetriphosphatase pump, an enzyme that controls the movement of ions into the heart.
Digoxin: A Comprehensive Guide and Nursing Interventions - rn101
Digoxin is a widely used medication in the treatment of heart failure and atrial fibrillation. Understanding its mechanism of action, indications for use, dosage and administration, potential side effects, nursing interventions, patient education, and safety precautions is essential for healthcare professionals involved in the care of patients ...
Digoxin Nursing Implications and Patient Teachings
2023年12月28日 · Digoxin Mechanism of Action. Inhibits the sodium-potassium ATPase pump, causing calcium influx thereby, promoting cardiac contractility. Increases cardiac contraction force and velocity, resulting in positive inotropic effects.
6.7 Cardiac Glycosides – Nursing Pharmacology
Mechanism of Action. Digoxin works by inhibiting the sodium and potassium pump, which results in an increase in intracellular sodium and an influx of calcium into cardiac cells, causing the cardiac muscle fibers to contract more efficiently and …
Digoxin: Uses, Interactions, Mechanism of Action - DrugBank …
Mechanism of action. Digoxin exerts hemodynamic, electrophysiologic, and neurohormonal effects on the cardiovascular system. 7 It reversibly inhibits the Na-K ATPase enzyme, leading to various beneficial effects. The Na-K ATPase enzyme functions to maintain the intracellular environment by regulating the entry and exit of sodium, potassium, and ...

Mechanism: Digoxin works by inhibiting the sodium and potassium pump, which results in an increase in intracellular sodium and an influx of calcium into cardiac cells, causing the cardiac muscle fibers to contract more efficiently and increase cardiac output
Digoxin (Lanoxin) - Inotropes - Pharmacological Nursing - Picmonic
Digoxin is used in people with atrial fibrillation by slowing down the conduction in the AV node, thereby reducing ventricular rate. Digoxin increases vagal activity, thereby decreasing heart rate by slowing depolarization of pacemaker cells in the AV node.
