Description
Curator's Comment: description was created based on several sources, including: https://www.drugs.com/dosage/cefditoren.html http://www.rxlist.com/spectracef-drug.htm http://www.wikidoc.org/index.php/Cefditoren

Cefditoren pivoxil is a semi-synthetic cephalosporin antibiotic for oral administration. It is a 3rd generation cephalosporin that is FDA approved for the treatment of acute bacterial exacerbation of chronic bronchitis, community acquired pneumonia, infection of skin and/or subcutaneous tissue, and pharyngitis/tonsillitis. Cefditoren is a cephalosporin with antibacterial activity against gram-positive and gram-negative pathogens. The bactericidal activity of cefditoren results from the inhibition of cell wall synthesis via affinity for penicillin-binding proteins (PBPs). Common adverse reactions include diarrhea, nausea and candida vaginitis. Co-administration of a single dose of an antacid which contained both magnesium (800 mg) and aluminum (900 mg) hydroxides or co-administration of a single dose of intravenously administered famotidine (20 mg) reduced the oral absorption of a single 400 mg dose of cefditoren pivoxil administered following a meal. Co-administration of probenecid with cefditoren pivoxil resulted in an increase in the plasma exposure of cefditoren.

SPECTRACEF

Approved Use

SPECTRACEF® (cefditoren pivoxil) is indicated for the treatment of mild to moderate infections in adults and adolescents (12 years of age or older) which are caused by susceptible strains of the designated microorganisms in the conditions listed below. Acute Bacterial Exacerbation of Chronic Bronchitis caused by Haemophilus influenzae (including ß-lactamase-producing strains), Haemophilus parainfluenzae (including ß-lactamase producing strains), Streptococcus pneumoniae (penicillin susceptible strains only), or Moraxella catarrhalis (including ß-lactamase-producing strains). Community-Acquired Pneumonia caused by Haemophilus influenzae (including ß-lactamase-producing strains), Haemophilus parainfluenzae (including ß-lactamase-producing strains), Streptococcus pneumoniae (penicillin-susceptible strains only), or Moraxella catarrhalis (including ß-lactamase producing strains). Pharyngitis/Tonsillitis caused by Streptococcus pyogenes. NOTE: SPECTRACEF® is effective in the eradication of Streptococcus pyogenes from the oropharynx. SPECTRACEF® has not been studied for the prevention of rheumatic fever following Streptococcus pyogenes pharyngitis/tonsillitis. Only intramuscular penicillin has been demonstrated to be effective for the prevention of rheumatic fever. Uncomplicated Skin and Skin-Structure Infections caused by Staphylococcus aureus (including ß-lactamase-producing strains) or Streptococcus pyogenes. To reduce the development of drug-resistant bacteria and maintain the effectiveness of SPECTRACEF® and other antibacterial drugs, SPECTRACEF® should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Sample Use Guides

In Vivo Use Guide
Acute bacterial exacerbation of chronic bronchitis: 400 mg twice a day for 10 days. Community-acquired pneumonia: 400 mg twice a day for 14 days Tonsillitis/Pharyngitis and Uncomplicated Skin or Soft Tissue Infection: 200 mg twice a day for 10 days
Route of Administration: Oral
In Vitro Use Guide
The level of cefditoren activity against S. pneumoniae (MIC(90,) 0.5 microg/mL) was superior to all marketed oral cephalosporins and at least equal to amoxicillin +/- clavulanate. H. influenzae (MIC(90,) 0.016-0.03 microg/mL) and M. catarrhalis (MIC(90,) 0.06-0.5 microg/mL) were also very susceptible to cefditoren. cefditoren was active against oxacillin-susceptible staphylococci (MIC(90,) < or = 1 microg/mL) at a level comparable to cefuroxime axetil, cefaclor or cefprozil.
