An interpretation of the Hill equation: time course of diuretic response after furosemide administration in man.
- MedicineJournal of pharmacobio-dynamics
- 1991
The Hill equation, which has been widely used without a definite rationale, for correlation between pharmacologic response intensity and drug concentration is revealed as an approximate equation of the response function.
Understanding the Dose-Effect Relationship
- Biology, MedicineClinical pharmacokinetics
- 1981
The design of rational dosing regimens for clinical therapeutics cannot be performed with a knowledge of pharmacokinelics alone, and the linking of pharmacokinetics and pharmacodynamics to predict firstly the dose-concentration, and then the concentration-effect relationship is required.
A modern view of pharmacokinetics
- Biology, MedicineJournal of Pharmacokinetics and Biopharmaceutics

This paper contains references to over 160 articles which suggest evidence on nonlinearities in drug absorption, distribution, metabolism and excretion, and the pharmacokinetics of drug action, which are reviewed in a format of six tables.

The time courses of blood levels, tissue levels and amounts excreted of an administered drug and its formed metabolites can be monitored simultaneously with observed pharmacological, toxicological or…
The use of kinetic-dynamic interactions in the evaluation of drugs
- BiologyPsychopharmacology
- 2005
This review shows, with reference to psychotropic drugs, how, in simple terms, it is possible to relate pharmacokinetics with pharmacodynamics, and how such relationships may provide a greater insight into drug activity and enhance drug development.
Molecular Mechanisms of Drug Action and Pharmacokinetic-Pharmacodynamic Models

The predictive potential of the pharmacokinetic-pharmacodynamic models should prove useful in evaluating pharmaceutical formulations with controlled drug delivery.
Drug-absorption analysis from pharmacological data. I. Method and confirmation exemplified for the mydriatic drug tropicamide.
- Medicine, BiologyJournal of pharmaceutical sciences
- 1971
It is demonstrated that through the suitable use of intravenous dose-effect curves, the postulation of hypothetical models for pharmacon-receptor site interaction is obviated and the relationship between the quantity of drug in body compartments (biophase) and the observed intensity of drug response is graphically provided.
Application of effect-compartment model to bumetanide-indomethacin interaction in dogs
- BiologyJournal of Pharmacokinetics and Biopharmaceutics
- 2005
An expanded pharmaco-dynamic model has been introduced in which the hypothetical effect compartment is linked, by a first-order process (Kue),to the urine compartment, and accommodates bumetanide's luminal site of action in the kidney tubule as well as the drug's temporal component.
The Efficiency Concept in Pharmacodynamics
- BiologyClinical pharmacokinetics
- 1999
It is concluded that the shape of the time course of drug presentation to its site of action is an independent determinant of overall response and the possibility of adjusting the drug input profile to maximise therapeutic effect per dose should be considered in designing administration schedules and in drug development.

Pharmacokinetic analysis of pharmacologic activity data can lead to better understanding of the relationship between dose and the multiple pharmacologic effects elicited by a drug, and it can facilitate the assessment of factors which account for individual variations in the response to drugs.
