Cefditoren is a semisynthetic, broad-spectrum, beta-lactamase-resistant, third-generation cephalosporin with antibacterial activity. Cefditoren binds to and inactivates penicillin-binding proteins (PBPs) located on the inner membrane of the bacterial cell wall. PBPs are enzymes involved in the terminal stages of assembling the bacterial cell wall and in reshaping the cell wall during growth and division. Inactivation of PBPs interferes with the cross-linkage of peptidoglycan chains necessary for bacterial cell wall strength and rigidity. This results in the weakening of the bacterial cell wall and causes cell lysis.

It 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.
Mechanism of Action of Cefditoren
Cefditoren, like other beta-lactam antibiotics (e.g., penicillins), is mainly bactericidal. It inhibits the third and final stage of bacterial cell wall synthesis by preferentially binding to specific penicillin-binding proteins (PBPs) that are located inside the bacterial cell wall. Penicillin-binding proteins are responsible for several steps in the synthesis of the cell wall and are found in quantities of several hundred to several thousand molecules per bacterial cell. Penicillin-binding proteins vary among different bacterial species. Thus, the intrinsic activity of cefditoren, as well as the other cephalosporins and penicillins against a particular organism, depends on its ability to gain access to and bind with the necessary PBP. Like all beta-lactam antibiotics, the ability of cefditoren to interfere with PBP-mediated cell wall synthesis ultimately leads to cell lysis. Lysis is mediated by bacterial cell wall autolytic enzymes (i.e., autolysins). The relationship between PBPs and autolysins is unclear, but it is possible that the beta-lactam antibiotic interferes with an autolysin inhibitor.
In general, the following organisms are considered clinically susceptible to cefditoren: Haemophilus influenzae (including beta-lactamase-producing strains), Haemophilus parainfluenzae (including beta-lactamase-producing strains), Moraxella catarrhalis (including beta-lactamase-producing strains), methicillin-sensitive Staphylococcus aureus (MSSA), penicillin-susceptible strains of Streptococcus pneumoniae, and Streptococcus pyogenes. Cefditoren is usually active against the following organisms in vitro, but the clinical significance of these data is unknown: Streptococcus agalactiae, Streptococcus Groups C and G, and Viridans streptococci (penicillin-susceptible and -intermediate strains).

Pregnancy & Lactation of Cefditoren
FDA pregnancy risk category B
Cefditoren crosses the placenta. Animal data reveal no teratogenic effects; however, a slight decrease in fetal weight was observed. Studies of doses 1 to 7.5 times the maximum recommended human dose in rabbits revealed a high incidence of abortion and maternal death. There are, however, no adequate and well-controlled studies of cefditoren use in pregnant women. Because animal studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed. Cefditoren has not been studied for use during labor and delivery. Treatment should be given only if clearly needed.
Lactation
Although no information is available on the use of cefditoren during breastfeeding, cephalosporins are generally not be expected to cause adverse effects in breastfed infants.
