Understanding Ciprofloxacin’s Mechanism of Action

Ciprofloxacin targets bacterial DNA replication. It achieves this by inhibiting two key enzymes: DNA gyrase and topoisomerase IV.

DNA gyrase is crucial for unwinding the supercoiled DNA, allowing replication to begin. Topoisomerase IV helps separate replicated DNA strands, allowing daughter cells to divide. Ciprofloxacin blocks these enzymes, effectively halting bacterial reproduction.

This inhibition is specific to bacterial enzymes; human cells lack these enzymes, minimizing the risk of human cell damage. However, individual reactions vary.

Enzyme Function Ciprofloxacin’s Effect
DNA Gyrase Unwinds supercoiled DNA Inhibits unwinding, stopping replication
Topoisomerase IV Separates replicated DNA strands Prevents strand separation, halting cell division

The bactericidal action of ciprofloxacin means it directly kills bacteria, unlike bacteriostatic drugs that only slow bacterial growth. This difference impacts treatment duration and effectiveness.
