Gemifloxacin
Gemifloxacin is a quinolone antibacterial agent with a broad-spectrum activity that is used in the treatment of acute bacterial exacerbation of chronic bronchitis and mild-to-moderate pneumonia. It is available in oral formulations. Gemifloxacin acts by inhibiting DNA synthesis through the inhibition of both DNA gyrase and topoisomerase IV, which are essential for bacterial growth.
