Levofloxacin is rapidly and essentially completely absorbed after oral administration. Peak plasma concentrations are usually attained one to two hours after oral dosing. The absolute bioavailability of Levofloxacin from a 500 mg tablet and a 750 mg tablet of Levofloxacin are both approximately 99%, demonstrating complete oral absorption of Levofloxacin. Following a single intravenous dose of Levofloxacin to healthy volunteers, the mean ± SD peak plasma concentration attained was ± mcg/mL after a 500 mg dose infused over 60 minutes and ± mcg/mL after a 750 mg dose infused over 90 minutes. Levofloxacin Oral Solution and Tablet formulations are bioequivalent.
