title: [A study on penetration of mezlocillin into the cerebrospinal fluid].
abstract: The concentration of antibiotics in cerebrospinal fluid is of great interest in therapeutics, especially for the treatment of the central nervous system. We studied the penetration of mezlocillin (MZPC) in 3 cases with V-P shunt and 7 cases after neurosurgical operation. After intravenous injection of 4 g MZPC in the 3 cases with V-P shunt, a peak concentration (0.26-3.6 micrograms/ml) of MZPC in the cerebrospinal fluid was reached in 2-4 hours. In the 7 cases after neurosurgical operation, cerebrospinal fluid was sampled at 4 hours after the intravenous injection of 4 g MZPC by spinal tap. Concentrations of MZPC in cerebrospinal fluid ranged from 1.1 to 17.5 micrograms/ml. The mean maximum concentration of MZPC was 5.85 micrograms/ml, which exceeded 90% MIC (minimal inhibitory concentration) against S. epidermidis, E. faecalis, H. influenzae. It is concluded MZPC can be useful for the prophylaxis of meningitis.
