    Abstract:
    Levofloxacin, the optical S-(-) isomer of ofloxacin, was compared with ofloxacin in the treatment of complicated urinary tract infections (UTIs). Patients eligible for the trial were randomly assigned to either a daily 300 mg of levofloxacin or 600 mg of ofloxacin for 10 consecutive days. The double blind design was achieved by a double-dummy technique utilizing placebo of both test drugs. Efficacy variables measured were: urine white blood cell counts for the effects on pyuria, urine cultures for effects on bacteriuria, subjective symptoms, and overall clinical efficacy which combined results from effects on bacteriuria, pyuria and subjective symptoms. Safety endpoints were the incidence of adverse events and laboratory test monitoring after a 10-day treatment. A total of 104 patients were enrolled into this trial and 46 patients were evaluable for efficacy endpoints. Most patients with culture-negative (48 cases), mixed flora (5 cases), and less than 10,000 colony forming units/mL of bacteria (3 cases) were excluded from analyses. None of the demographic and baseline characteristics were significantly different between treatments (p > 0.05). Therapeutic effects upon bacteriuria for both treatment groups were similar with a response rate of 90.0% for levofloacin and 88.5% for ofloxacin. Efficacy on the subjective symptoms revealed response rates of 90.0% in the levofloxacin group and 80.7% in the ofloxacin group, with the overall clinical efficacy of 90% in the levofloxacin and 84.6% in the ofloxacin groups. All the efficacy variables measured between treatments were not statistically different which indicated an equivalent efficacy in the treatment of complicated UTIs (p > 0.05). Of the 104 patients exposed to the test medications, only three having adverse effects. One developed epigastralgia in the levofloxacin group, and 2 developed a headache in the ofloxacin treatment. All events were moderate in severity and were resolved quickly after medication. Four laboratory data abnormalities were observed (defined by 25% as exceeding the normal range), and were considered to not be related to the test medications. Both antibiotics were efficacious in the treatment of complicated UTIs (response rates ranging from 80 to 90%) and were well tolerated. Levofloxacin demonstrated comparable antibacterial effects and safety profiles with double potency dosage, compared to the ofloxacin.
