The bio-availability of beta-acetyldigoxine (Novodigal) alone and combined with oxyfedrine (Ildamen-Novodigal).
The bio-availability of various galenic preparations of beta-acetyldigoxine was tested in six healthy probands after a single oral dose (1 mg). The availability parameters were calculated from the areas under the plasma concentration curves and from the cumulative urinal excretion. There was no significant difference between the bio-availabilities of Novodigal (beta-acetyledigoxine tablets), Ildamen-Novodigal (beta-acetyldigoxine and oxyfedrine) and an alcoholic solution of beta-acetyldigoxine. Correlation calculations showed that the determination of the plasma concentration courses up to six hours after substance application are most favourite in regard to judging the absorption processes of digoxine preparations. For the assessment of the bio-availability, the methods of comparing the areas under the blood level curves of 0 to 6 hrs and of comparing the cumulative urinal excretion over a period of 24 hrs were of equal validity.
