About Zelox-L 750 Tablet

Clinical Uses

How It Works (Mechanism of Action)

Levofloxacin works by interfering with the bacteria's ability to reproduce and repair their DNA. This action stops the growth of the bacteria, allowing the body's immune system to eliminate the infection.

Scientifically, Levofloxacin inhibits bacterial DNA gyrase and topoisomerase IV, enzymes crucial for DNA replication and repair. By blocking these enzymes, it effectively halts bacterial cell division and leads to cell death.
