Staphylococcus aureus remains one of the most common and troublesome microorganisms causing disease in humans, despite the development of effective antibiotics. Linezolid is a member of a new class of synthetic antibiotics called oxazolidinones, introduced into therapy due to the increasing resistance of Gram-positive pathogens to traditional antibiotics. Information about the pharmacokinetics and tolerability profile of linezolid in the pediatric population mostly derive from adult studies and especially in the neonatal field relatively few data are available. Here we summarize linezolid's characteristics and report data available in the literature regarding linezolid use in newborns and children. For this purpose, a Medline search was performed between 1990 and 2006 involving the term "linezolid" combined with the terms "newborn", "infant", "child", "pediatrics". Additional information was obtained from Reactions Weekly.

Linezolid is the first member of a new generation of antibiotics, the synthetic oxazolidinones, to become available, with a broad spectrum of in vitro activity against gram-positive organisms, including methicillin-resistant Staphylococcus aureus, vancomycin-resistant Enterococcus faecalis and vancomycin-resistant E. faecium. Linezolid is showing great promise currently for the treatment of multiresistant gram-positive bacterial infections, especially complicated skin infections, catheter-induced bacteremia or nosocomial pneumonia both in the community and in a hospital setting, in children and in adults. Although most recent reports are favorable and anticipatory of a more extensive use of linezolid in appropriately selected pediatric population groups in the near future, following treatment failure of conventional antimicrobial agents, more clinical trials are, however, required to investigate the safety profile and tolerability of this new antibiotic in the pediatric population.
