Propofol pharmacokinetics

Pharm-95A03 Define Phase I and Phase II reactions in drug metabolism. Propofol, marketed as Diprivan, among other names, is a short-acting medication that results in a decreased level of consciousness and a lack of memory for events. Its uses include the starting and maintenance of general anesthesia, sedation for mechanically ventilated adults, and procedural sedation. Se hela listan på drugs.com 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. The goal of this study was to determine if the presence of a frontal brain tumour influences propofol pharmacokinetics and pharmacodynamics and existing PK-PD model performance. Propofol pharmacokinetics readily crosses the placenta; however, it is rapidly cleared from the neonatal circulation. The amount of propofol excreted into milk within 24 hours of induction of anesthesia dose not mandate discontinuation of breastfeeding.

Anesth Analg 77:1031-1040, 1993 Pharmacokinetics The pharmacokinetics of propofol are well described by a three compartment linear model with compartments representing the plasma, rapidly equilibrating tissues, and slowly equilibrating tissues. Following an IV bolus dose, there is rapid equilibration between the plasma and the brain, accounting for the rapid onset of anesthesia. Despite the very long elimination half-life, blood propofol concentrations appeared to approach steady state within 20 min rather than the 4-5 half-lives normally expected.

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.

The disposition of propofol was similar after The pharmacokinetics of propofol were investigated in two groups of five Scottish blackface sheep undergoing surgery for the implantation of subcutaneous tissue pouches. 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.

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. 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.

The pharmacokinetic parameters of propofol that have been studied in various animal species are summarized in Table 141-43;45. 2.3.1. Propofol blood

The pharmacokinetics of propofol were investigated in two groups of five Scottish blackface sheep undergoing surgery for the implantation of subcutaneous tissue pouches. 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 intravenously (group 2). characterize propofol PK over a wide range of body weights. An allometric model using TBW as the size descriptor of volumes and clearances was superior to other size descriptors to characterize propofol PK in obese patients. Keywords: anaesthetics i.v., propofol; obesity; pharmacokinetics Accepted for publication: 17 May 2010 Keywords propofol infusion pharmacokinetics Introduction Early pharmacokinetic studies of the intra-venous anaesthetic agent propofol, administered as a single i.v. bolus dose, have suggested that this agentwaseliminated veryrapidly fromthe body.
