4.2 Drug Indication

Indicated for the treatment of acute bacterial exacerbations of chronic bronchitis (ABECB), acute bacterial otitis media, pharyngitis, and tonsilitis.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Ceftibuten is an antibiotic with bactericidal actions.


5.2 MeSH Pharmacological Classification

Anti-Bacterial Agents

Substances that inhibit the growth or reproduction of BACTERIA. (See all compounds classified as Anti-Bacterial Agents.)

5.4 ATC Code

J - Antiinfectives for systemic use

J01 - Antibacterials for systemic use

J01D - Other beta-lactam antibacterials

J01DD - Third-generation cephalosporins

J01DD14 - Ceftibuten


5.5 Absorption, Distribution and Excretion

Absorption

Rapidly absorbed following oral administration.


Route of Elimination

Ceftibuten is excreted in the urine; 95% of the administered radioactivity was recovered either in urine or feces.


Volume of Distribution

0.21 L/kg [adult subjects]

0.5 L/kg [fasting pediatric patients]


5.6 Metabolism/Metabolites

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.


5.7 Mechanism of Action

Ceftibuten exerts its bactericidal action by binding to essential target proteins of the bacterial cell wall. This binding leads to inhibition of cell-wall synthesis.
