Ceftibuten is a third-generation cephalosporin antibiotic. It is an orally-administered agent. Cefalexin is used to treat acute bacterial exacerbations of chronic bronchitis (ABECB), acute bacterial otitis media, pharyngitis, and tonsilitis.
Indication
Used to treat acute bacterial exacerbations of chronic bronchitis (ABECB), acute bacterial otitis media, pharyngitis, and tonsilitis.
Pharmacology
Ceftibuten is a third-generation cephalosporin antibiotic.
Toxicity
Overdosage of cephalosporins can cause cerebral irritation leading to convulsions.
Affected Organisms
Enteric bacteria and other eubacteria
Biotransformation
A study with radiolabeled ceftibuten administered to 6 healthy adult male volunteers demonstrated that cis-ceftibuten is the predominant component in both plasma and urine. About 10% of ceftibuten is converted to the trans-isomer is approximately 1/8 as antimicrobially potent as the cis-isomer.
Absorption
Rapidly absorbed following oral administration.
Protein Binding
Ceftibuten is 65% bound to plasma proteins. The protein binding is independent of plasma ceftibuten concentration.
Elimination
Ceftibuten is excreted in the urine; 95% of the administered radioactivity was recovered either in urine or feces.
