Cefotiam Treatment in Children: Evidence of Subtherapeutic Levels

Background: Cefotiam, a second-generation cephalosporin, is a broad-spectrum antibiotic with good antibacterial action against both gram-negative and gram-positive bacteria. It is used widely in clinical practice, although bacterial drug resistance makes its clinical use problematic. The authors hypothesized that subtherapeutic concentrations of cefotiam leads to bacterial resistance. The present study was conducted to evaluate whether the standard cefotiam dosing regimen resulted in a subtherapeutic concentrations in children. Method: Data were prospectively collected from pediatric patients with suspected or confirmed community-acquired pneumonia who were receiving cefotiam at the standard dosing regimen (40–80 mg/kg, 2 or 3 times daily). A blood sample was collected after 70%–100% of the dosing interval, and plasma concentrations were determined by high-performance liquid chromatography using an ultraviolet detector. Results: The data from 88 patients (age, 3.0 ± 2.8 years; weight, 15.4 ± 8.3 kg) were used for analysis. The average of cefotiam concentrations was 0.06 mcg/mL (range:
