Description: Cefdinir is a cephalosporin antibiotic. It is active against numerous Gram-positive and Gram-negative bacteria, including lactamase-producing E. coli, K. oxytoca, K. pneumoniae, and P. aeruginosa clinical isolates (MICs = 0.25-16 g/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.
Cefdinir is an orally active, beta-lactamase stable cephalosporin with a broad spectrum of activity. Compared to other oral cephalosporins, cefdinir is more potent against Gram-positive bacteria, especially Staphylococci. Its activity against Gram-negative bacteria such as E.coli,K. pneumoniae and P.mirabilis is similar to cefixime, but superior to cefaclor and cephalexin.
