Levofloxacin

Overview

Basic Info

SummaryLevofloxacin is an effective synthetic antibacterial agent used for treating different types of bacterial infections such as respiratory, urinary tract, skin and soft tissue, and bacterial prostatitis. It belongs to the fluoroquinolones class of antibiotics and prevents the DNA replication process in bacteria, eventually leading to cell death. Levaquin is one of the popular brand names for this drug, available in oral, intravenous, and eye drop forms.Due to its broad-spectrum activity, Levofloxacin is effective against both Gram-positive and Gram-negative bacteria, including those that are resistant to other antibiotics. This feature makes it a valuable option in treating serious infections caused by multidrug-resistant bacteria.Levofloxacin was patented in 1985 and approved by the US Food and Drug Administration by JANSSEN PHARMS in 1996. Since then, it has been widely used and considered as an important therapeutic option in the treatment of different bacterial infections.
