lanoxicaps and Calphron Interactions

Interactions between lanoxicaps(digoxin) and Calphron (calcium acetate)

digoxin and calcium acetate (Major Drug-Drug)

GENERALLY AVOID: The administration of parenteral calcium preparations, particularly by rapid IV injection, may precipitate serious cardiac arrhythmias in digitalized patients. The mechanism is probably related to the additive or synergistic inotropic effects of calcium and digitalis glycosides on the myocardium.

MANAGEMENT: Intravenous calcium should preferably not be used in patients receiving digitalis glycosides, or it should be given slowly or in small amounts to avoid high serum calcium concentrations. Patients should be monitored for development of arrhythmias.
