Reduce doses if patient has been given cardiac glycoside in the preceding 2 wk. Adult: IV Emergency heart failure For patients who have not received cardiac glycosides in the previous 2 wk: 0.5-1 mg via infusion as a single dose or in divided doses. Maintenance: Usually via oral admin.

Contraindication ::

Digitalis toxicity, ventricular tachycardia/fibrillation, obstructive cardiomyopathy. Arrhythmias due to accessory pathways (e.g. Wolff-Parkinson-White syndrome).

Drug Precautions ::

Cardiac dysrhythmias, hypokalaemia, hypertension, IHD, hypercalcaemia, hypomagnesaemia, electroconversion, chronic cor pulmonale, aortic valve disease, acute myocarditis, congestive cardiomyopathies, constrictive pericarditis, heart block, elderly, renal impairment, abnormalities in thyroid function; pregnancy. IV digoxin can only be given to patients who have not received cardiac glycosides in the preceding 2 wk.

Drug Side Effects ::

Extra beats, anorexia, nausea and vomiting. Diarrhoea in elderly, confusion, dizziness, drowsiness, restlessness, nervousness, agitation and amnesia, visual disturbances, gynaecomastia, local irritation (IM/SC inj), rapid IV admin may lead to vasocostriction and transient hypertension. Potentially Fatal: Cardiac arrhythmias in combination with heart block.

Pregnancy category ::

3

Drug Mode of Action ::  

Digoxin is a cardiac glycoside which has positive inotropic activity characterized by an increase in the force of myocardial contraction. It also reduces the conductivity of the heart through the atrioventricular (AV) node. Digoxin also exerts direct action on vascular smooth muscle and indirect effects mediated primarily by the autonomic nervous system and an increase in vagal activity.

Drug Interactions ::

Effectiveness reduced by phenytoin, neomycin, sulphasalazine, kaolin, pectin, antacids and in patients receiving radiotherapy. Metoclopramide may alter the absorption of solid dosage forms of digoxin. Blood levels increased by calcium channel blockers, spironolactone, quinidine and calcium salts. Potentially Fatal: Electrolyte imbalances such as hypokalaemia and hypomagnesemia (e.g. admin of potassium-losing diuretics, corticosteroids) can increase the risk of cardiac toxicity.
