Propofol: Pharmacokinetics, Medical Uses and Potential Health Effects Several studies have reported analgesic effects of subhypnotic doses of propofol on
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 is administered undiluted intravenously by continuous infusion. Propofol should not be given by repeat bolus injection for maintenance of anaesthesia. Dyck GB, Shafer SL.

Propofol is an intravenous hypnotic drug that is used for induction and maintenance of sedation and general anaesthesia.
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. Using propofol as an example, explain briefly the importance of clearance. (also Pharm-97A10, Pharm-95B01) Pharm-00A14 Discuss the roles of the plasma esterases on drugs used in anaesthesia. Pharm-95B03 Give a brief account of drug protein binding and outline its significance. Pharm-95A03 Define Phase I and Phase II reactions in drug metabolism. Pharmacokinetics of propofol can be well described by a three-compartment model.
Unlike polymorphism of the UGT1A9 gene, the tested CYP2C9 and CYP2B6 gene polymorphisms are not independent predictors of the pharmacokinetics of propofol. The prevalence of obesity has markedly increased worldwide. Obese patients pose significant challenges to anesthesiologists with regard to accurate dosing of anesthetics due to potentially altered pharmacokinetics (PK).
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.

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. Our clinical experiences regarding the use of propofol evaluated by the COMFORT-B in young children in the pediatric surgical intensive care unit (PSICU) have recently been published by Prins et al. 8In the current article, propofol pharmacokinetics and pharmacodynamics characterized by use of the COMFORT-B and BIS on the postoperative sleep pattern in nonventilated infants are described using population modeling, to select appropriate doses in infants and to support the safe and effective The pharmacokinetics and pharmacodynamics of propofol in a modified cyclodextrin formulation (Captisol) versus propofol in a lipid formulation (Diprivan): an electroencephalographic and hemodynamic study in a porcine model. Egan TD (1), Kern SE, Johnson KB, Pace NL. Models of propofol pharmacokinetics and pharmacodynamics developed in patients without brain pathology are widely used for target-controlled infusion (TCI) during brain tumour excision operations.

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. 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 ]. Clinical Pharmacokinetics and Pharmacodynamics of Propofol Marko M. Sahinovic1,3 • Michel M. R. F. Struys1,2 • Anthony R. Absalom1 The Author(s) 2018 Abstract Propofol is an intravenous hypnotic drug that is used for induction and maintenance of sedation and general anaesthesia. It exerts its effects through potentiation of the PROPOFOL (2,6-diisopropylphenol) is a water-insoluble intravenous anesthetic that is available as an oil-in-water lipid emulsion with 10% soybean oil (Diprivan®; AstraZeneca, London, United Kingdom). 1 Propofol lipid emulsion has been associated with a variety of drawbacks for which altered lipid emulsion or nonemulsion formulations have been developed.
