Klinisk prövning på General Anesthesia: Pharmacokinetic of
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. The pharmacokinetics of propofol administered as long term infusions were determined in 12 intensive care unit patients (two female; mean age 58 yr, mean weight 66.9 kg) requiring sedation during mechanical ventilation. Patients were recruited after having been administered propofol for 24 h.

So far, the pharmacokinetics of propofol has not been studied in Indian children. We believe that this pharmacokinetic characterization of propofol will help in better management of these patients undergoing surgery under total intravenous anesthesia (TIVA) in our setup. 12 ASA (American Society of Anesthesiologists) grade I patients, 5 to 12 years old planned for elective surgery will be 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.

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. 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 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). Here we determined the PK and pharmacodynamics (PD) of propofol for anesthesia induction in morbidly obese (MO) subjects (body mass index >35 kg/m2) at two dosing regimens This study, however, shows that epidural blockade affects the pharmacokinetics of propofol through a reduction in propofol clearance. We successfully fitted a 3-compartment model to the data. Covariates were included in the model based on the BIC, evaluated for every possible combination of influence of a covariate on any of the 6 pharmacokinetic parameters.

However, if a steady concentration is maintained, we can use the integrated pharmacokinetic-pharmacodynamic model to compare ihe time to the offset of drug effect for propofol and midazolam, as shown in Figure 5. Propofol pharmacokinetics, with or without 2% benzyl alcohol, were characterized by rapid distribution, a long elimination phase, and a large volume of distribution.
