Brief Summary:
Description of the pharmacokinetic parameters of the amoxicillin / clavulanic acid to healthy voluntary obese after oral and intra venous administration Determination of the pharmacokinetic parameters of amoxicillin / clavulanic acid obtained from plasmatic concentrations of intravenous injection (IV) and oral administrations. The criterion of evaluation allowing to answer our main objective corresponds to the parameters estimated by the pharmacokinetic model of the concentrations obtained from the data IV and by the pharmacokinetic model of the concentrations obtained from the oral data. The following pharmacokinetic parameters will be considered at every obese volunteer's for both molecules (amoxicillin and clavulanic acid) from the concentrations by pharmacokinetic analysis of population.
The main evaluation criteria are PK parameters of amoxicillin / clavulanic:
* Cl, systematic plasmatic clearance
* Vd, volume of distribution
* ASC 0-oo, area under the curve time - concentration
* T1/2, half-life time
* F, bioavailability after oral administration
* Ka, constant of speed of absorption
Detailed Description:
Main objective Description of the pharmacokinetic parameters of the amoxicillin / clavulanic acid to healthy voluntary obese after oral and intra venous administration
Secondary objectives
* Define dosage plans optimized with the antibiotic treatment to the obese subject
* Ensure an adequacy of the treatment with the related infection
* Formulate recommendations of dosage adaptations for a better individualization of treatments, by estimating several plans of doses by simulation to reach various PK/PD goals according to different theoretical MIC
Methodology
The pharmacokinetic analysis will be realized by approach of population allowing the estimation of the average parameters of amoxicillin and clavulanic acid as well as the interpersonal variability after an administration IV and an oral administration. Parameters's population and their variability will be estimated with the SAEM algorithm implemented in the software Monolix ( www.lixoft.eu ).
For the main objective, PK parameters PK of amoxicillin and clavulanic acid will be determined to day 1 and day 2. They will be described by means of indicators of position (average and median) and of dispersal (standard deviations, quartiles).
For secondary objectives, the profiles concentration/time of 1000 obese subjects will be determined by Monte Carlo method from PK parameters estimated at the balance by the model. For every feigned profile, the time during which the plasmatic concentration of amoxicillin and clavulanic acid is superior to a panel of theoretical MIC will be calculated by means of curves concentration - time determined for each of the subjects.
