title: Concentrations of lomefloxacin in radicular cyst and oral tissues following single or multiple oral administration.
abstract: Concentrations of lomefloxacin in serum, the wall and fluid of radicular cyst, gingiva, and jawbone following single or multiple oral administration were measured. The highest concentrations of lomefloxacin in serum, cyst wall, cyst fluid, gingiva, and jawbone occurred at 3 h after multiple administration, and were 2.31 micrograms/ml, 4.06 micrograms/g, 1.54 micrograms/ml, 4.72 micrograms/g and 2.79 micrograms/g, respectively. The mean concentration ratios of wall/serum, fluid/serum, fluid/wall, gingiva/serum, and jawbone/serum at the highest concentrations were 1.74, 0.73, 0.47, 2.52 and 1.20, respectively. Although most lomefloxacin concentrations in cyst and oral tissues following single oral administration did not exceed the MICs for 80% of clinically isolated strains of alpha-hemolytic streptococci, Staphylococcus aureus and Niesseria spp., most of those obtained after multiple oral administration exceeded the MICs except in the case of fluid.
