title: The use of pharmacokinetic/pharmacodynamic principles to predict clinical outcome in paediatric acute otitis media.
abstract: Double tympanocentesis studies of children with acute otitis media, carried out over an 11-year period, were used to confirm that pharmacokinetic (PK) and pharmacodynamic (PD) parameters can be used as predictors of the bacteriological and clinical efficacy of antimicrobial agents. Predicted susceptibilities of common respiratory pathogens, such as Streptococcus pneumoniae and Haemophilus influenzae, were compared with the bacteriological outcome of treatment in which the high-dose formulation of amoxicillin/clavulanate (90mg/kg/day) given twice daily achieved the greatest bacteriological eradication rates for an oral agent. Further analysis of the data has indicated that failure to eradicate bacteria from the middle ear fluid is strongly correlated with clinical failure.
