How It Works

This medicine works by inhibiting two key bacterial enzymes: DNA gyrase and topoisomerase IV. These enzymes are essential for bacterial DNA replication, transcription, repair, and recombination. By blocking them, the medicine prevents bacteria from copying their genetic material and repairing damage, leading to bacterial cell death. This dual-target mechanism also helps reduce the likelihood of resistance developing during treatment.

Mechanism Steps

1
Penetration into bacterial cell: The medicine penetrates the bacterial cell wall and reaches the cytoplasm.
2
Binding to DNA gyrase and topoisomerase IV: It binds to and inhibits these enzymes, which are responsible for maintaining DNA topology during replication.
3
Inhibition of DNA replication: Without functional enzymes, the bacterial DNA cannot be replicated or repaired, leading to double-strand breaks.
4
Bacterial cell death: The accumulation of DNA damage triggers bacterial cell death, clearing the infection.
