He Haixia, et al. Distribution of norfloxacin in body fluids of rabbits after iv adminitration[J]. Journal of Chongqing Medical University, 1999,(2).DOI:
CSF and urine samples of six female rabbits were obtained at different times before and following administration of an iv dose of 25mg/kg. The concentration of norfloxacin in samples were determined by HPLC. The drug - time data were analyzed with 3p87 program. The results showed that the concentration of norfloxacin in serum
bile and urine were much higher than MIC90 for most pathogenic bacteria. The concentration of norfloxacin in CFS(peak level) was equal to or higher than MICd90 for common pathogenic bacteria. Experimental conalusion is that norfloxacin could distribute quickly to tissues fluids and reach the effective level of killing bacteria
