Tissue penetration and pharmacokinetics of lomefloxacin following multiple doses

The pharmacokinetics of lomefloxacin were studied after three days of oral administration of 400 mg/day lomefloxacin. Following the final dose the concentrations in serum, urine and cantharidin-induced inflammatory fluid were measured by a microbiological assay. The mean peak serum level was 4.9 mg/l at a mean time of 0.8 h. The mean serum elimination half-life was 6.2 h. The mean maximum inflammatory fluid level attained was 3.2 mg/l at 2.7 h. Urinary recovery accounted for the greater part of lomefloxacin's elimination.
