Application

Pefloxacin mesilate dihydrate EP Reference standard, intended for use in laboratory tests only as specifically prescribed in the European Pharmacopoeia.

Biochem/physiol Actions

Pefloxacin inhibits the bacterial enzymes DNA gyrase and topoisomerase IV, which are needed for the transcription and replication of bacterial DNA. DNA gyrase is thought to be the primary quinolone target for gram-negative bacteria. Topoisomerase IV is thought to be the primary target in gram-positive organisms. The inhibition of the topoisomerases results in strand breakage of the bacterial chromosome, supercoiling, and resealing. Therefore, DNA replication and transcription is inhibited . Pefloxacin is an analog of norfloxacin.

Pefloxacin is a synthetic fluoroquinolone that functions an antibacterial agent. It is an analog of norfloxacin.
Mode of Action: Pefloxacin prevents bacterial DNA replication by inhibiting DNA gyrase.
Antimicrobial spectrum: Pefloxacin is highly active against Staphylococcus aureus, E. coli, other enterobacteria, and Pseudomonas aeruginosa. Active against gram-positive bacteria and excellent activity against gram-negative bacteria.
