Description and Uses

Cefdinir is a cephalosporin antibiotic. It is active against numerous Gram-positive and Gram-negative bacteria, including β-lactamase-producing E. coli, K. oxytoca, K. pneumoniae, and P. aeruginosa clinical isolates (MICs = 0.25-16 μg/ml). Cefdinir is protective against sepsis induced by strains of S. aureus or H. influenzae in mice with 50% protective dose (PD₅₀) values of 2.7-35 and 3.1-5.8 mg/kg, respectively. Formulations containing cefdinir have been used in the treatment of Gram-positive and Gram-negative infections.

A broad spectrum antibiotic targeting both Gram-positive and Gram-negative pathogens
