Question: What does digoxin do?

What does digoxin do to the heart rate?

Digoxin is a type of drug called a cardiac glycoside. Their function is to slow your heart rate down and improve the filling of your ventricles (two of the chambers of the heart) with blood. For people with atrial fibrillation, where the heart beats irregularly, a different volume of blood is pumped out each time.

How does digoxin work in the body?

Digoxin belongs to a class of medications called cardiac glycosides. It works by affecting certain minerals (sodium and potassium) inside heart cells. This reduces strain on the heart and helps it maintain a normal, steady, and strong heartbeat.

Does digoxin lower blood pressure?

Because digoxin does not affect blood pressure, it is sometimes used alone in a person with atrial fibrillation who has naturally low blood pressure. But these cases are rare. “Sometimes, there is no other effective rate-controlling treatment that doesn’t also lower blood pressure.

What does digoxin do for AFIB?

Digoxin in atrial fibrillation

In patients with AF, the primary effect of digoxin is slowing down atrioventricular (AV) conduction, leading to a reduction in ventricular response at rest, but much less so during exercise.

When should you not take digoxin?

Withhold dose and notify health care professional if pulse rate is <60 bpm in an adult, <70 bpm in a child, or <90 bpm in an infant. Notify health care professional promptly of any significant changes in rate, rhythm, or quality of pulse.

Does digoxin cause more harm than good?

Overall, a meta-analysis of 11 observational studies by Ouyang et al (2015), including the AFFIRM Trial and TREAT-AF studies, found digoxin use was associated with greater risk for mortality in patients with AF, regardless of concomitant heart failure.

Who should not take digoxin?

For people with ventricular fibrillation: Digoxin can’t be used if you have ventricular fibrillation. It may make your ventricular fibrillation worse. For people with Wolff-Parkinson-White syndrome: If you have Wolff-Parkinson-White syndrome, you’re at a higher risk for an abnormal heart rhythm.

Why is digoxin no longer used?

While the cause of the apparently elevated risk of dying with digoxin is not certain, it is likely that it is due to a higher risk of sudden death from cardiac arrhythmias. Most experts are now at least somewhat reluctant to recommend using digoxin for controlling the heart rate in people with atrial fibrillation.

Does digoxin make you tired?

What happens if I overdose on Digoxin (Lanoxin)? Overdose symptoms may include nausea, vomiting, loss of appetite, and feeling tired.

Does digoxin affect the kidneys?

Digoxin efficacy did not differ by level of GFR (P = 0.19 for interaction). Renal dysfunction is strongly associated with mortality in stable outpatients with heart failure, notably in patients with estimated GFR <50 ml/min per 1.73 m2. The effect of digoxin did not differ by level of renal function.

Is digoxin safe for elderly?

The elderly are at an increased risk of digoxin toxicity. Low dosages of digoxin appear to be effective in the treatment of heart failure due to systolic dysfunction and may reduce the incidence of digitalis toxicity in these patients.

What is the alternative to digoxin?


Is digoxin safe for AFib?

“Based on our study, digoxin should be avoided in patients with AFib, particularly if symptoms can be alleviated with other treatments,” Lopes said. “We showed that starting digoxin was associated with increased risk of death and sudden death, regardless of the presence of heart failure.
