Serum and urine drug concentrations were detected by HPLC method in 9 healthy volunteers after oral administration of 400 mg lomefloxacin hydrochloride capsules. The serum drug concentration-time profile conformed to the one-compartment open model. Cmax was 2 32±0 47 μ g/ml
Tmax was 3 20±1 19h
T 1/2 was 6 18±1 09 h and AUC was 27 96±5 35 μ g/ml.h. The total clearance rate for 36h was 56 10%.
