Clinical Pharmacokinetics of Gentamicin in Neonates

Gentamicin is a bactericidal aminoglycoside antibiotic, it inhibits the protein synthesis. Gentamicin is active against the majority of aerobic gram-negative bacilli such as Pseudomonas, Klebsiella and Escherichia coli. The gentamicin doses are 3 mg/kg once-daily for preterm newborns 35 weeks of gestation. The monitoring of gentamicin serum concentration is recommended when infants are treated for 48 hours or more. The gentamicin peak concentration must be at least 8 times the minimum inhibitory concentration (MIC) to be bactericidal and the gentamicin trough concentration must be
