Digoxin Uses:-

The main use of digoxin is to control the ventricular rate (and therefore improve cardiac output) in patients with atrial fibrillation. Digoxin is usually given orally, but if it is impossible, or if a rapid effect is required, it may be given intravenously.  This is acceptable in most settings, but if clinical circulation attitudes are more urgent, therapeutic plasma concentration can be achieved more rapidly by giving a loading dose.

Pediatrics: Reduce dose necessary.

Adverse Drug Reaction’s (ADR’s):-

Tachycardia, Cardiac arrhythmia,  heart block.

Side effects:-

Anorexia,  nausea, vomiting, abdominal pain, fatigue, headache, mental confusion, restlessness, Weakness, Rash, Dizziness.

Mechanism Of Action:-

The mechanism of action inhibits digoxin Sodium / Potassium + adenosine Triphosphates (Na/ K + ATPase).  It increases intracellular concentrations by intracellular Sodium accumulation and reduced sodium exchange. The increase in intracellular Calcium + availability is attributed to the positive isotropic effect of digoxin.  Excessive inhibition of sodium / potassium ATPase causes many non-cardiac (dysrhythmogenic) toxic effects.

Ventricular slowing due to increased vagal activity in the AV node.  Improving ventricular filling during diastole improves cardiac output in patients with atrial fibrillation.  Clinical progression is measured by measuring the heart rate (at the peak): epicardial rates can be achieved at 70 – 80 per minute during rest.

Unfortunately, because vagal activity is suppressed during exercise (when the heart rate is controlled by sympathetic activity), rate control is not usually achieved when exercising.

Drug-Drug Interactions:-

Digoxin Major Drug Interactions:-

Digoxin +Amiodarone:-

These combinations of medicines may lead to higher blood levels of digoxin. Digoxin levels ought to be firmly checked on the off chance that you begin on Amiodarone..

It is necessary to inform your doctor regarding all different medications you utilize
