[A comparative study of the toxic and therapeutic effects of digoxin and its immobilized form].

It was shown on different species of laboratory animals (frogs, mice, rats) that digoxin immobilized on the copolymer was 8-15 times less toxic that its usual preparation. In this case glycoside fixed on the copolymer preserves completely its specific cardiotonic effect, i.e., possesses a wider range of the therapeutic action.
