Ceftibuten Brand Name– Cedax

What is Ceftibuten

Ceftibuten is an oral, third-generation cephalosporin.

Ceftibuten is more beta-lactamase stable compared to other beta-lactamase stable cephalosporins; however, ceftibuten is inactivated by type I beta-lactamase produced by EnterobacterPseudomonas, and Serratia species.

In addition, resistance occurs in over 15% of strains of Citrobacter freundii and Morganella morganii.

Although ceftibuten possesses activity against a variety of gram-negative and gram-positive bacteria, gram-positive activity with ceftibuten is less than for first generation agents.

Ceftibuten, like cefixime, has minimal activity against staphylococci, group B streptococci (Streptococcus agalactiae), and the enterococci.

About 95% of penicillin-susceptible Streptococcus pneumoniae have ceftibuten MICs less than 8 mcg/mL; however, ceftibuten and other orally administered beta-lactam antibiotics are not active against penicillin-resistant S. pneumoniae. In one study of patients with acute otitis media, ceftibuten was less effective than cefaclor in patients with infection due to S. pneumoniae (80% vs. 95%).

Therefore, the manufacturer recommends that ceftibuten should only be given empirically for acute otitis media when adequate antimicrobial coverage against S. pneumoniae has been previously administered.

Since ceftibuten is acid-stable, it does not require administration as a prodrug as do cefuroxime or cefpodoxime.

Ceftibuten was approved by the FDA December 20, 1995 for treatment of respiratory infections.

Limited data support the use of ceftibuten for the treatment of dysentery, pneumonia, or sinusitis.
