Digoxin may be prescribed for a child to treat heart defects. Possible side effects in children are: dysrhythmia, nausea, vomiting, a slower-than-normal heart rate and anorexia. [4] Children may demonstrate side effects if they are breastfed. Digoxin is also absorbed by the infant in utero. [5]
For heart rate control (atrial fibrillation), plasma levels are less defined and are generally titrated to a goal heart rate. Typically, digoxin levels are considered therapeutic for heart rate control between 0.5 and 2.0 ng/mL (or 0.6 and 2.6 nmol/L). [37] In suspected toxicity or ineffectiveness, digoxin levels should be monitored.
Digoxin helps alleviate symptoms and reduce hospitalizations related to heart failure, but it does not offer any mortality-reducing benefits. [86] Digoxin may be considered in patients who remain symptomatic despite receiving treatment with a first-line combination of an ACE inhibitor (or ARNI ), a beta-blocker , and a mineralocorticoid ...
The level of digoxin for treatment is typically 0.5-2 ng/mL. [8] Since this is a narrow therapeutic index, digoxin overdose can happen. A serum digoxin concentration of 0.5-0.9 ng/mL among those with heart failure is associated with reduced heart failure deaths and hospitalizations. [9]
Calcium channel blockers are generally contraindicated due to their negative inotropic effect, particularly in cardiomyopathy caused by amyloidosis. [ 18 ] [ 19 ] Digoxin, calcium channel blocking drugs and beta-adrenergic blocking agents provide little benefit, except in the subgroup of restrictive cardiomyopathy with atrial fibrillation. [ 20 ]
The effect of these compounds on the cardiovascular system presents a reason for concern, as they can directly affect the function of the heart through their inotropic and chronotropic effects. In terms of inotropic activity, excessive cardiac glycoside dosage results in cardiac contractions with greater force, as further calcium is released ...
Cardiovascular disease in women is an integral area of research in the ongoing studies of women's health. Cardiovascular disease (CVD) is an umbrella term for a wide range of diseases affecting the heart and blood vessels, including but not limited to, coronary artery disease, stroke, cardiomyopathy, myocardial infarctions, and aortic aneurysms.
It is an acetyl derivative of digoxin and an isomer of β-acetyldigoxin. α-Acetyldigoxin increases the contractility of the heart by its positive inotropic effect on cardiac muscle. [citation needed] The effects of α-acetyldigoxin begin 3–4 hours after administration, and maximize after 6–8 hours.
