Tosufloxacin is a fluoroquinolone antibiotic primarily used in the treatment of various bacterial infections. It is effective against a wide range of Gram-positive and Gram-negative bacteria, making it useful for respiratory tract infections, urinary tract infections, and skin infections. Its ability to penetrate tissues and cells allows it to combat intracellular pathogens effectively. Additionally, it is often prescribed for infections resistant to other antibiotics or when patients have limitations with other medications, providing a reliable alternative. It is also used for preventing infections after surgery in some cases. However, its use must be strictly under medical supervision to avoid side effects and antibiotic resistance.
