Pharmacokinetics/Pharmacodynamics and Clinical Outcomes of β-lactams in Critically Ill Patients

Meropenem and imipenem are broad-spectrum carbapenem antibiotic and are frequently prescribed in critically ill patients with severe infections. These patients show several pathophysiological changes that may alter the carbapenem pharmacokinetic (PK) normally found in other populations. Although the PK of carbapenems has been widely studied, most studies have been conducted on small populations, and clinical outcome data are sparse. Therefore, the aims of this study are (i) describe the population pharmacokinetic parameters of meropenem and imipenem in critically ill subject (ii) evaluate the pharmacodynamic of meropenem and imipenem as a predictor of clinical treatment outcome.
