Overview
Levofloxacin, marketed as Levaquin, is a broad-spectrum fluoroquinolone antibiotic active against both gram-positive and gram-negative bacteria. It works by inhibiting DNA gyrase and topoisomerase IV, essential for bacterial replication. Approved in the late 1990s, it is valued for its high oral bioavailability and once-daily dosing.
