About Zelox-L 500 Tablet

How It Works (Mechanism of Action)

Levofloxacin works by interfering with the DNA replication process in bacteria, which stops their growth and reproduction. This action helps the body's immune system to fight off the infection more effectively.

Scientifically, Levofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, enzymes crucial for DNA replication and repair. By blocking these enzymes, Levofloxacin prevents the bacteria from multiplying, leading to their eventual death.
