Pharmacokinetics/Pharmacodynamics in Otitis Media: Comparison of Time-Dependent Antibiotics in Middle Ear Fluid

Abstract

Background: An effective dosing regimen of b-lactam and macrolide antibiotics for otitis media involving S. pneumoniae (SP) requires that drug concentrations in middle ear fluid (MEF) remain above the MIC (T>MIC) of the isolate for at least 35-50% of the dosing interval. The purpose of these analyses was to determine the probability of obtaining 35-50% T>MIC in MEF using Monte Carlo simulation (MCS) for CDC-recommended (amoxicillin) or FDA-approved dosing regimens of AMX, cefaclor, cefprozil, cefixime, cefpodoxime, ceftibuten, ceftriaxone, and clarithromycin.
