    Notes: Summary Single doses of β-methyl-digoxin 0.4 mg were given to groups of 17 – 18 healthy volunteers as an intravenous infusion lasting 2 hours, or orally as Lanitop Liquidum® or Lanitop® tablets. The serum glycoside concentration and urinary glycoside excretion were measured over 8 and 32 h. The absolute bioavailability from the oral preparations in comparison with the infusion was lower for the first 8 h than for the entire 32 h of the investigation; the relative bioavailability from tablets was the same as from the solution for both periods. For both periods the area under the serum concentration/time curve and the urinary glycoside excretion were significantly lower after administration of the tablets than after intravenous infusion. Taking the average of both parameters, the absolute bioavailability of β-methyl-digoxin was about 80% from the solution and about 70% from the tablets. In 18 patients undergoing intravenous or oral therapy with β-methyl-digoxin steady state glycoside concentrations were compared in a cross-over study of intravenous maintenance therapy with Lanitop® ampoules or oral treatment with Lanitop® tablets. For a standard daily dose of 0.2 mg β-methyl-digoxin the serum concentrations were 1.35±0.10 ng/ml during both intravenous and oral administration. The intra-individual variation in glycoside concentration after changing from intravenous to oral maintenance therapy, or vice versa, was about the same as during continued intravenous or oral administration. It is concluded that the rate of rise of serum concentration after a single dose may be a useful indicator of the rate of absorption, but that the area under the serum concentration/time curve and the urinary glycoside excretion up to 32 h are unsuitable for determining equivalent doses of different formulations or routes of administration of digitalis glycosides.

    Fine structure and hyperfine structure in the excited configuration 5p 26s of the antimony I spectrum (1986)

    Notes: Abstract By optical interference and VUV spectroscopy the doublet system of SbI 5p 26s was investigated, so that now the hyperfinestructure of all 8 levels of 5p 26s (A- andB-splitting constants) are known. From the analysis we receive a spin-orbit parameter ζ5p =3,538(57) cm−1 and from the hyperfine-analysis single electron splitting constantsa 5p 01 =52.4(4.6),a 5p 10 =−1.6(7.3),a 5p 12 =72.3(2.3),a 6s 10 =91.7(4.1),b 5p 02 =−49.6(1.1) andb 5p 11 =30.4(3.2) (all values in mK). For all calculations in the fs- and hfs-analysis the 5p 26s 2 D 3/2 has to be excluded (see discussion). With the figures given above the quadrupole moment121 Q(5p 26s)=−0.44(3) barn was obtained. It is in good agreement with the121 Q(5p 3). For the core-polarization by the 5p electron in the innerfieldns-shells (n=1, 2, 3, 4, 5) and the unpaired 6s electron a field of +500(300) kG was obtained.

    Theoretical and experimental analysis of the fine structure and hyperfine structure in the configurations 5p6s and 5p6p of the antimony II spectrum (1986)

    Notes: Abstract From 17 transitions in the singly ionized Sb II spectrum the hyperfine structure (A andB splitting constants) of the complete excited configurations 5p6s and 5p6p were determined by means of optical interference spectroscopy. In addition, a theoretical analysis both of the fine structure and also of the hyperfine structure was carried out (in the case of 5p6p of the general typenpn′p for the first time in literature). For the 3 levels 5p6p 3 P 1, 5p7p 3 D 2 and 5p6p 1 P 1 a different classification was found and consistent values for the fine structure parameters, mixing coefficients and single electron hyperfine structure splitting parametersa nl ik andb nl ik were obtained. The three new determinations in Sb II of the quadrupole moment (in barn) of121Sb (Q(5p6s)=−0.55(5);Q(5p6p)=−0.57(5) from the 5p-electron andQ(5p6p)=−0.7(2) from the 6p-electron) are well agreeing with each other but differ to former values from SbI. The core polarization and isotope shift of the lines, however, are compatible with our former results in SbI.
