Abstract

BACKGROUND: Oral second and third generation cephalosporins are undergoing continuing research and development in the arena of pediatric infectious disease in an attempt to fill voids created by existing agents in the quest for the "ideal" antimicrobial. This paper reviews the in vitro antimicrobial activity (pharmacodynamics) and pharmacokinetics of cefdinir, an extended spectrum oral cephalosporin, with an emphasis on those aspects relevant to the pediatric patient population. METHODS: A MEDLINE literature search was conducted for the years 1985 through 2000, identifying all English language papers examining the in vitro antimicrobial activity and human pharmacokinetics of cefdinir. Bibliographies of these papers were reviewed, as were relevant data on file with the manufacturer. DATA SYNTHESIS: Cefdinir exhibits broad range in vitro activity against Gram-positive and Gram-negative aerobes. It exhibits superior activity against Gram-positive aerobes, compared with drugs like cefixime, ceftibuten, cefuroxime and cefpodoxime. In addition it is stable to hydrolysis by many of the common betalactamases. The pharmacokinetic parameters of cefdinir in children are similar to those obtained in adults using similar milligram per m2 doses (300, 600 mg in adults = 7, 14 mg/kg in children, respectively). CONCLUSIONS: The pharmacodynamic and pharmacokinetic characteristics of cefdinir as described in this paper, as well as the results of the clinical trials program, support the use of this agent in the treatment of a wide variety of pediatric infectious diseases.
