Description | Levofloxacin is a fluoroquinolone antibiotic and the optical S-(-) isomer of racem ic ofloxacin . It reportedly carries 8 to 128-fold more activity against both gram-negative and gram-positive bacteria compared to R-(+)-ofloxacin 1 and remains stereochemically stable following administration (i.e. it does not invert to the inactive isomer). Levofloxacin, along with other quinolones such as gatifloxacin and moxifloxacin , is a member of the third generation of fluoroquinolones, colloquially referred to as the "respiratory quinolones" due to improved activity against gram-positive bacteria commonly implicated in respiratory infections. Levofloxacin was first approved by the FDA in 1996, and was approved in Canada and se veral South American countries soon after. 1 |
