title: Congestive heart failure and toxic digoxin levels: role of cholestyramine.
abstract: We report 2 patients with congestive heart failure and concomitant toxic serum digoxin levels in whom cholestyramine administration increased clearance of digoxin and decreased serum digoxin elimination half-lives. Cholestyramine's gastrointestinal binding of enterohepatically-recycled and enterally-secreted digoxin enhanced elimination, allowing a more rapid return to therapeutic drug levels.
