Why thiazides and loop diuretics are contraindicated in patients on digitalis therapy?
Electrolyte disturbance is believed to be the main mechanism responsible for the digoxin–diuretic interactions [17, 18], and use of diuretics including thiazides and loop diuretics has been found to cause potassium or magnesium deficit [19–22].
Why is digoxin given for heart failure?
Digoxin, also called digitalis, helps an injured or weakened heart pump more efficiently.
