Feedback:
Digoxin immune Fab is an antigen-binding fragment derived from specific antidigoxin antibodies. The drug is used for the treatment of life-threatening digoxin intoxication when serum levels are greater than 10 ng/mL. Inamrinone is a phosphodiesterase inhibitor that acts as a cardiotonic agent. Verapamil hydrochloride is a calcium channel blocker. Quinidine is an antiarrhythmic agent that when taken with digoxin increases both the therapeutic and toxic effects of digoxin.
