Leflox 500mg IV Infusion contains the active ingredient Levofloxacin, which belongs to a group of antibiotics called fluoroquinolones. It is used to treat infections caused by bacteria, such as respiratory tract infections, urinary tract infections, skin and soft tissue infections, and other types of infections. The medication works by inhibiting the activity of bacterial DNA gyrase and topoisomerase IV, which are essential enzymes needed by bacteria to replicate their DNA and divide, thereby preventing the growth and multiplication of bacteria. Leflox is usually given as an intravenous infusion over a period of time prescribed by the doctor, and the dosage may vary depending on the severity of the infection being treated.
