title: [Biological availability of digoxin from a combination drug].
abstract: In a randomized cross-over study with 14 voluntary test persons the absolute biological availability of digoxin in Card-Dusodril 1/8 and 1/4 respectively was investigated. 6 test persons received 4 drag. Card-Dusodril 1/8 (= 0.5 mg digoxin), 8 test persons 4 drag. Card-Dusodril 1/4 (= 1 mg digoxin) orally, in comparison to the corresponding group with intravenously applied digoxin as standard. Based on the cumulative digoxin excretion in the urine an absolute biological availability of Card-Dusodril 1/8 of 79%, of Card-Dusodril 1/4 of 76% could be demonstrated. With regard to an average resorption of oral digoxin preparations of approx. 70%, the present values, which correspond in direct comparison to those of acetyl digoxin, can be considered good. Maximum serum levels were achieved after 86 +/- 6.8 minutes which also indicates a quick resorption.
