[Cholestyramine for digoxin intoxication].

Cholestyramine, a bile acid sequestering resin, has been reported to bind digitalis in vitro. We gave 4 g every 6 hours to 3 patients with non-life threatening digoxin intoxication. In all 3 serum digoxin concentrations and digoxin half-life decreased: from 50 to 32 hours, from 50 to 10 hours and from 46 to 16 hours in the 3 cases, respectively. Cholestyramine is potentially useful and safe adjunct medication for non-life threatening digoxin intoxication.
