Penetration of ceftibuten into middle ear fluid

Antimicrob Agents Chemother. 1996 Jun;40(6):1394-6. doi: 10.1128/AAC.40.6.1394.

Abstract

The penetration of ceftibuten, an extended-spectrum oral cephalosporin, into middle ear fluid (MEF) was evaluated in pediatric patients during a course of daily oral doses of 9 mg/kg of body weight for 10 days. Plasma and MEF collected at 2, 4, 6, or 12 h after at least 3 days of dosing were analyzed for ceftibuten by a high-pressure liquid chromatography method, and the data were used to calculate pharmacokinetic parameters. Plasma and MEF had almost identical maximum concentrations (Cmax) of ceftibuten (14 micrograms/ml). These Cmax values in MEF during acute otitis media were well in excess of the MIC for 90% of the isolates of each of four major pathogens in this disease. The time to Cmax was longer in MEF (4 h) than in plasma (2 h). Excellent penetration (71%) of ceftibuten into MEF was observed on the basis of the area under the curve ratio (MEF/plasma). These data clearly indicate that ceftibuten penetrated well into the MEF to yield clinically effective concentrations.
