详细说明

DrugBank - DB01415

• Drug Groups: approved
• Description: 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.
• Distribution: * 0.21 L/kg [adult subjects]; * 0.5 L/kg [fasting pediatric patients]
