As with most beta-lactam antibiotics, the bactericidal activity of ceftibuten results from the inhibition of bacterial cell wall synthesis. Due to its chemical structure, ceftibuten is highly stable to beta-lactamases. Many beta-lactamase-producing microorganisms, which are resistant to penicillins or other cephalosporins, may be inhibited by ceftibuten.
As with other oral antibiotics, duration of treatment generally ranges from 5-10 days. For treatment of infections due to Streptococcus pyogenes, a therapeutic dose of Ceftibuten should be administered for at least 10 days.
Adults: Recommended Dose: 400 mg daily. Ceftibuten capsules may be taken without regard to mealtime. For treatment in the following indications, this may be administered as 400 mg once daily: Acute bacterial sinusitis, acute bronchitis, acute exacerbations of chronic bronchitis, and complicated or uncomplicated urinary tract infections.
For the treatment of community-acquired pneumonia in patients in whom oral therapy is appropriate, the recommended dose is 200 mg every 12 hrs.
Children: Recommended Dose: 9 mg/kg/day (maximum of 400 mg daily) of the oral suspension. This may be administered as a single daily dose for treatment in the following indications: Pharyngitis with or without tonsillitis, acute otitis media with effusion and complicated or uncomplicated urinary tract infections.
For the treatment of acute bacterial enteritis in children, the total daily dosage may be administered in 2 divided doses of 4.5 mg/kg every 12 hrs. Children weighing >45 kg or >10 years may receive the recommended adult dose.
Ceftibuten suspension may be taken approximately 1 or 2 hrs before or after mealtime. Shake bottle well before measuring each dose.
