| Abstract: | The concentrations of metronidazole, clindamycin, chloramphenicol, cefoxitin, ticarcillin, and moxalactam in the serum, femurs, and scapulae of normal rats were measured microbiologically 0.5, 1, 1, and 4 h after intravenous injection of 15-, 15-, 20-, 40-, 75-, and 30-mg/kg doses of the respective drugs. By 0.5 h metronidazole reached levels of 3.0 micrograms/g in compact femoral bone and 2.7 micrograms/g in cancellous scapular bone. Clindamycin and chloramphenicol reached levels of 8.1 and 6.1 micrograms/g, respectively, at 0.5 h. Cefoxitin penetrated bone to a level of 2.6 micrograms/g, whereas ticarcillin and moxalactam failed to reach significant levels in bone after single intravenous doses. |
