Levofloxacin is a third-generation fluoroquinolone antibiotic that is synthetic and broad-spectrum. Levofloxacin is a chiral fluorinated carboxyquinolone chemically. The enzymes necessary for DNA replication, transcription repair, and recombination, bacterial topoisomerase IV and DNA gyrase, are inhibited by levofloxacin. It exhibits efficacy against a variety of gm-ve and gm+ve bacteria in vitro.

Warfarin can make you bleed more easily.
