The safety and pharmacokinetics of a once-daily high intravenous
dose of levofloxacin (750 mg) in 18 healthy volunteers were studied in
a double-blind, randomized, placebo-controlled, single-center parallel
group study. Levofloxacin was well tolerated, and higher maximum
concentration of drug in serum and area under the concentration-time curve values were achieved. For difficult-to-treat infections, high
daily doses of levofloxacin may be beneficial, and intravenous administration may be preferred in certain clinical settings, such as
when treating patients in intensive care units, warranting further evaluation.
