Pharmacokinetics of propofol (Diprivan):5. Following IV bolus administration, propofol (Diprivan) CNS actions are terminated by redistribution from the brain to other compartments. This process occurs with a redistribution halftime in the 2-8 minute range.

Lampotang S, Lizdas D, Gravenstein N, Yavas S (2006): Web Simulation of Propofol Pharmacokinetics. 2021-01-26 A (COMFORT-B or BIS units) is the amplitude of the night dip, and 2π/Fr (minutes) is the frequency of the oscillations. Propofol effect (PEF) was related to the pharmacokinetic model–predicted individual propofol concentration (C ij) by a simple E max model: Pharmacokinetics: propofol.

Propofol is an intravenous hypnotic drug that is used for induction and maintenance of sedation and general anaesthesia. It exerts its effects through potentiation

2 The pharmacokinetics of propofol were best described by a three-compartment model. Weight was found to be a significant covariate for elimination clearance, the two intercompartmental clearances, and the volumes of the central compartment, the shallow peripheral compartment, and the deep peripheral compartment; power functions with exponents smaller than 1 yielded the best results. The pharmacokinetics and protein binding of propofol were studied in ten patients with cirrhosis and in ten control patients undergoing elective surgery.

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.

The pharmacokinetics and protein binding of propofol were studied in ten patients with cirrhosis and in ten control patients undergoing elective surgery. 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. Propofol pharmacokinetics, with or without 2% benzyl alcohol, were characterized by rapid distribution, a long elimination phase, and a large volume of distribution.

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. Se hela listan på journals.lww.com Se hela listan på academic.oup.com 2021-01-26 · Pharmacokinetics and Pharmacodynamics of Propofol designed to achieve a particular plasma concentration, they result in administration of a larger than necessary induc tion Propofol, the recently marketed intravenous induction agent for anaesthesia, is chemically unrelated to earlier anaesthetic drugs. This highly lipophilic agent has a fast onset and short, predictable duration of action due to its rapid penetration of the blood-brain barrier and distribution to the CNS, followed by redistribution to inactive tissue depots such as muscle and fat.

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. 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.
