This interactive simulation of propofol pharmacokinetics is based on a 3-compartment model either from Gepts et al, Anesthesia & Analgesia 66:1256-63, 1987 (default) or Fechner et al, Anesthesiology 99:303-13, 2003. Click to play simulation.

We have compared the pharmacokinetics of propofol as an infusion in 10 control and 10 patients with cirrhosis. Anaesthesia was induced within 3-4 min during administration of an infusion of propofol 21 mg kg-1 h-1. After 5 min, the infusion was decreased in a stepwise manner to 12 mg kg-1 h-1 and subsequently 6 mg kg-1 h-1.

Propofol pharmacokinetics, with or without 2% benzyl alcohol, were characterized by rapid distribution, a long elimination phase, and a large volume of distribution. No differences were noted between treatments with the exception of clearance from the second compartment (CLD2), which was 23.6 and 38.8 mL kg(-1) minute(-1) in the P and P28 treatments, respectively.

2018-07-18 · Like most anaesthetics, propofol is a γ-aminobutyric acid (GABA) receptor agonist. It has a favourable pharmacokinetic (PK) and pharmacodynamic (PD) profile, which has resulted in it becoming the most commonly used intravenous anaesthetic for the past three decades [ 2, 3, 4, 5, 6, 7 ].

After premedication with acepromazine and papaveretum, anaesthesia was induced with either propofol at 4 mg kg-1 intravenously (group 1) or with a mixture of propofol at 3 mg kg-1 and ketamine at 1 mg kg-1 … 1993-11-01 Propofol pharmacokinetics in the obese BJA 449. variability in model parameters was modelled by exponen-tiating random effects (equivalent to assuming a log-normal distribution). P i = P TV ×e h i where P i is the parameter value (e.g. CL and V) of the ith patient, P Pharmacokinetic (PK) and pharmacodynamic (PD) models are used in target-controlled-infusion (TCI) systems to determine the optimal drug administration to achieve a desired target concentration in a central or effect-site compartment. Our aim was to develop a PK–PD model for propofol that can predict the bispectral index (BIS) for a broad population, suitable for TCI applications.

Propofol (2,6 diisopropylphenol) is a widely used sedative/hypnotic drug in anesthesiology and intensive care. Because it is very insoluble in water, propofol is currently formulated as 1% propofol in a lipid emulsion containing soybean oil, glycerol, and egg phosphatide (Diprivan®). Pharmacokinetics The pharmacokinetics of propofol are well described by a three compartment linear model with compartments representing the plasma, rapidly equilibrating tissues, and slowly He has published 19 papers about the pharmacokinetics of propofol. Pharmacokinetics involves the study of the dilution of drug in a patient's blood stream.

All patients received 2.5 mg.kg-1 propofol as an intravenous bolus injection for the induction of anesthesia. Whole blood propofol concentrations … The hypothesis that the propofol-in-cyclodextrin formulation would exhibit pharmacokinetic and pharmacodynamic behavior that was substantially similar to the propofol-in-lipid formulation was confirmed.IMPLICATIONS: A modified cyclodextrin-based formulation of propofol has been developed that may mitigate some of the problems associated with propofol in lipid emulsion.

1. The pharmacokinetics of propofol in an emulsion formulation ('Diprivan') have been studied after single bolus doses to rats, dogs, rabbits and pigs, and after single and multiple infusions to dogs. Venous blood propofol concentrations were determined by h.p.l.c. with u.v. or fluorescence detection. Curve fitting was performed using ELSFIT. 2.
