    Pharmacokinetic model based on circulatory transport (1979)
    Springer
    European journal of clinical pharmacology 16 (1979), S. 287-293 
    Details
    ISSN: 1432-1041
    Keywords: linear system theory ; perfusion model ; cardiac output ; pulmonary extraction ; pharmacokinetics
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Assessment of pharmacokinetics in terms of circulatory drug transport is proposed using the methods of linear system theory. In this model-independent approach drug distribution and disposition are characterized by the total extraction ratio, the mean residence time in the body and the volume of distribution at steady state. In analyzing concentration(c)-time(t) data, the procedure requires calculation only of the areas under the c(t)-and c(t)×t-curves to estimate kinetic parameters, and for prediction of the steady state concentration following continuous infusion or multiple doses. Pulmonary clearance of drugs is included in the theory.

    Pharmacokinetics of isosorbide-5-nitrate in renal failure (1986)
    Springer
    European journal of clinical pharmacology 30 (1986), S. 349-350 
    Details
    ISSN: 1432-1041
    Keywords: isosorbide-5-nitrate ; renal failure ; pharmacokinetics
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary The pharmacokinetics of the antianginal drug isosorbide-5-nitrate (IS-5-N) was studied in 20 patients with varying degrees of chronic renal failure after repeated oral doses of standard 20 mg tablets t.d.s. Blood samples were taken in the steady state on the 2nd and 28th days, and the plasma level was assayed by HPLC. There was no statistically significant difference in C max ss , t1/2 and AUC 0–8 ss between the 2nd and 28th days, nor was a difference found between patients with mild and severe renal failure.

    Rapid achievement of a serum concentration plateau of digoxin through controlled infusion (1983)
    Springer
    European journal of clinical pharmacology 25 (1983), S. 455-457 
    Details
    ISSN: 1432-1041
    Keywords: digoxin ; concentration plateau ; pharmacokinetics ; systolic time intervals ; optimal infusion scheme ; dose-response data
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Using a volume-controlled infusion pump, a mean serum plateau level of digoxin of 4–5 ng/ml was rapidly achieved and maintained in 6 healthy volunteers. The infusion scheme was calculated on the basis of data published on the pharmacokinetics and pharmacodynamics of digoxin following bolus intravenous injection. The magnitude of the response (change in electromechanical systole) at the end of the plateau phase was comparable to that observed with the concentration in the therapeutic range at steady state.

    A note on the rôle of generalized inverse Gaussian distributions of circulatory transit times in pharmacokinetics (1984)
    Springer
    Journal of mathematical biology 20 (1984), S. 95-102 
    Details
    ISSN: 1432-1416
    Keywords: pharmacokinetics ; generalized inverse Gaussian distribution ; recirculatory model ; renewal theory
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Mathematics
    Notes: Abstract Based on a stochastic pharmacokinetical model (which mirrors topological properties of the circulatory system) it is shown by reinterpreting results of Wise (1974) that if the transit times of circulating drug molecules have a generalized inverse Gaussian distribution the corresponding residence times are gamma distributed. The condition that the probability of elimination of a drug molecule in a single circulatory passage is sufficiently small appears to be valid for most drugs. Thus theoretical evidence is given for fitting blood concentration-time curves following bolus injection of a single dose by power functions of time.
