Background:

Cefditoren pivoxil is a new-third generation cephalosporin antibiotic that has a broad spectrum of activity against Gram-positive and Gram-negative bacteria, including common respiratory and skin pathogens.Target: AntibacterialCefditoren pivoxil, a new-third generation cephalosporin antibiotic that has recently been granted approval in Spain, shows important activity over a large part of the pathogens causing skin, soft tissue and respiratory tract infections, including Gram-negative and Gram-positive bacteria. Cefditoren is also marketed under the name Meiact. Cefditoren has a broad spectrum of activity and has been used to treat bacterial infections of the skin and respiratory tract including bronchitis, pneumonia, and tonsillitis. The following represents MIC susceptibility data for a few medically significant microorganisms.Cefditoren has shown excellent in vitro activity against the Gram-positive pathogens penicillin-susceptible and -intermediate Streptococcus pneumoniae, S. pyogenes and methicillin-susceptible Staphylococcus aureus. Cefditoren was inactive against methicillin-resistant S. aureus. Of the important Gram-negative pathogens, cefditoren had potent antibacterial effects against beta-lactamase-positive and -negative Haemophilus influenzae, H. parainfluenzae and beta-lactamase-positive and -negative Moraxella catarrhalis.
