Application

Levofloxacin is a broad-spectrum antibiotic used in pharmacokinetic , antibiotic resistance , and resistance prevention studies. Antibiotic against bacterial respiratory tract infections.

Biochem/physiol Actions

Levofloxacin is active against Gram-positive and Gram-negative bacteria. It inhibits DNA gyrase (type II topoisomerase) and topoisomerase IV, thereby inhibiting cell division.

To determine the steady-state plasma, epithelial lining fluid (ELF), and alveolar macrophage (AM) concentrations of levofloxacin and ciprofloxacin. Multiple-dose, open-label, randomized pharmacokinetic study. Thirty-six healthy, nonsmoking adult subjects were randomized either to oral levofloxacin, 500 or 750 mg once daily

The new fluoroquinolones (clinafloxacin, gatifloxacin, gemifloxacin, grepafloxacin, levofloxacin, moxifloxacin, sitafloxacin, sparfloxacin and trovafloxacin) offer excellent activity against Gram-negative bacilli and improved Gram-positive activity (e.g. against Streptococcus pneumoniae and Staphylococcus aureus) over ciprofloxacin. Ciprofloxacin still maintains the best in vitro activity

Levofloxacin is the L-form of the fluoroquinolone antibacterial agent, ofloxacin. In in vitro studies, levofloxacin demonstrated a broad range of activity against Gram-positive and -negative organisms and anaerobes. The drug is more active against Gram-positive organisms than ciprofloxacin, but less
