    Abstract:
    The transferability of tazobactam/piperacillin (TAZ/PIPC) to cerebrospinal fluid (CSF) was studied employing rabbits with experimental meningitis caused by Staphylococcus aureus. 125 or 250 mg/kg of TAZ/PIPC was intravenously administered to rabbits with experimental meningitis then concentrations of TAZ and PIPC in CSF and serum were measured. In the group to which 125 mg/kg of TAZ/PIPC was administered, mean concentration of TAZ in CSF was 7.3 and 2.4 micrograms/ml at 30 and 60 min after administration, respectively, and concerning PIPC, it was 10.1 and 3.5 micrograms/ml, respectively. CSF/serum ratio of TAZ was 29.4% and 31.4%, respectively, and that of PIPC was 24.3 and 35.6%, respectively. In the group to which 250 mg/kg of TAZ/PIPC was administered, mean concentration of TAZ in CSF was 16.5 and 12.6% micrograms/ml, respectively, and concerning PIPC, it was 25.6 and 18.2 micrograms/ml, respectively. CSF/serum ratio of TAZ was 22.1 and 56.1%, respectively, and that of PIPC was 12.2 and 51.9%, respectively. Addition of TAZ did not make significant change of transferability of PIPC to CSF. Considering the antibacterial effect of TAZ/PIPC against main causative organism of meningitis, this agent was thought to be effective for the treatment of purulent meningitis.
