LEVOFLOXACIN
Background and Date of Approval
Levofloxacin is a powerful antibiotic used to treat a wide range of bacterial infections. It belongs to a class of drugs known as fluoroquinolones. This medicine helps fight bacteria that cause infections in the lungs, urinary tract, skin, and more. It works by stopping the bacteria from multiplying, allowing the body to heal. Levofloxacin was approved by the U.S. Food and Drug Administration (FDA) in December 1996. Since then, it has become one of the commonly prescribed antibiotics worldwide due to its broad spectrum of action. Clinical trials and years of real-world use have confirmed its effectiveness and safety when used appropriately under medical supervision.
