Thrombocytopenia exposes patients to increased bleeding risk. This serious adverse event was observed with a frequency of approximately 2% in early clinical trials with the potent, orally bioavailable glycoprotein (GP) IIb/IIIa receptor antagonist ro

The disposition of XV459, a potent, selective GP IIb/IIIa antagonist, has been examined following intravenous administration of XP280, the benzenesulphonate salt, and 3H-SA202, the trifluroacetic acid salt, to male guinea pigs. A liquid chromatograph

A precursor-dependent model of indirect pharmacody-namic response which can describe tolerance and rebound was characterized in terms of the effects of changes in the fundamental properties of the drug on its response profiles. The model extends prev

Background Propofol when administered by brief infusion in a lipid-free formulation has a slower onset, prolonged offset and greater potency compared with an emulsion formulation. To understand these findings the authors examined propofol brain and l

Currently available software for nonlinear regression does not account for errors in both the independent and the dependent variables. In pharmacodynamics, measurement errors are involved in the drug concentrations as well as in the effects. Instead

Pharmacodynamics of general anesthetic agents generally exhibit biphasic concentration–effect relationships (i.e., an activation phase at low concentrations and inhibition at higher concentrations). These relationships are usually characterized wit

Propofol is a unique highly lipid-soluble anesthetic that is formulated in a fat emulsion (Diprivan) for intravenous (i.v.) use. It has the desirable properties of rapid onset and offset of effect following rapid i.v. administration and minimal accum

Background The goal of this investigation was to characterize the effects of thiopental on cardia output and regional blood flows in the rat. Blood flows influence thiopental pharmacokinetics. Acquisition of these data may ultimately permit evaluatio

The article by Verotta and Sheiner (1) provides a cogent extension of the indirect response models (IRM) of Dayneka et al. (2) to accommodate a linear "effect compartment" as a biophase for the drug and a nonlinear transformation of an endogenous med

We have developed a computer-controlled infusion pump to achieve rapidly and then maintain stable plasma thiopental concentrations in rats. Initially we derived the parameters of a triexponential pharma-cokinetic model for thiopental, administered as
