Population Pharmacokinetics of Anti-infectives in Hospitalized Patients

In case of sepsis, the therapeutic success is strongly influenced by the choice of anti-infectives (AI) in terms of spectrum, dosage and administration schedule. It is therefore critical to achieve adequate AI concentration as quickly as possible. This protocol aims to define a common framework to studies conducted jointly by the Antimicrobial Stewardship Tea, the Pharmacology department of Cochin hospital and within the APHP Centre hospital group for various AI in a range of specific study populations (intensive care unit patients, neutropenic patients…). These studies will use mathematical modeling methodologies to investigate the pharmacokinetics (PK) and pharmacodynamics (PD) of different AI including PK/PD targets or any other biological compartment. The effects of covariates on PK and PD parameters will be investigated to better explain the between-subject variability (BSV) and to ultimately suggest individualized dosage regimens.
