A predictive parameter of @entity3405 therapeutic efficacy is the time (T > MIC) while antibiotic serum concentrations are above the MIC of suspected bacteriological agents. This led us to carry out a randomised open study to compare the usually used intermittent administration of @entity52661 (three injections of 4 g/0.5 g a day) and continuous perfusion of 12 g/1.5 g a day by calculating these T > MIC. @entity1 from digestive reanimation department were randomised within two arms: continuous or intermittent administration. Sixteen takings of blood were executed over a forty-hour period. After liquid/liquid extraction, @entity3400 and @entity7120 serum concentrations were determined by HPLC with a reversed phase column ( @entity6173 ) and a UV spectrophotometry detection. Then, from the time-concentration curves we have evaluated the T > MIC for an enterobacteria (MIC = 8 micrograms/mL) and for Pseudomonas (MIC = 16 micrograms/mL). Concerning intermittent administration T > MIC were 74% (c > MICenterobacteria) and 62% (c > MICPseudomonas). These percentages in the continuous arm were 100% (c > MICenterobacteria) and 99% (c > MICPseudomonas). @entity7120 concentrations were low and even undetectable between each injection in the intermittent administration arm. This was not found within the continuous administration arm. In conclusion, for the intermittent administration, we observed some long periods occurring before each injection while antibiotic concentrations were under the MIC of most bacteria. During these same periods @entity7120 concentrations were under the efficacy threshold. These periods were not observed within the continuous administration arm.
