Levofloxacin is bactericidal and has a wide antibacterial spectrum that covers many gram-positive and gram-negative bacteria and anaerobes.
There is no cross-resistance between levofloxacin and other groups of antibacterial agents.
Food has a little effect on absorption o levofloxacin. it is rapidly and almost completely absorbed with bioavailability of 100%. it reaches the peak plasma concentration within 1 hour and penetrates well to different body tissues.
Levofloxacin has a duration of action of 24 hours and it is eliminated mainly via the kidney.
