Pefloxacin is a broad-spectrum antibiotic that is active against both Gram-positive and Gram-negative bacteria. It functions by inhibiting DNA gyrase, a type II topoisomerase, and topoisomerase IV, which is an enzyme necessary to separate replicated DNA, thereby inhibiting cell division.

Mechanism of action:

The bactericidal action of pefloxacin results from interference with the activity of the bacterial enzymes DNA gyrase and topoisomerase IV, which are needed for the transcription and replication of bacterial DNA. DNA gyrase appears to be the primary quinolone target for gram-negative bacteria. Topoisomerase IV appears to be the preferential target in gram-positive organisms. Interference with these two topoisomerases results in strand breakage of the bacterial chromosome, supercoiling, and resealing. As a result DNA replication and transcription is inhibited.


Fluoroquinolones are used to treat bacterial infections in many different parts of the body. They are both bactericidal and bacteriostatic, are effective against both gram positive and gram negative organisms including: Pseudomonas, gonoccoci, H. influenzae, Staphylococci, Streptococci, etc. It is not active against anaerobes. It is not effective for rhinitis, lnfluenza or other viral infections.
