Fosfomycin sodium 4gm, Fosfomycin trometamol 3g


Fosfomycin is a bactericidal antibiotic agent. It inhibits an enzyme-catalyzed reaction in the first step of the synthesis of the bacterial cell wall.

It irreversibly inhibits enolpyruvate transferase (MurA), which prevents the formation of N-acetylmuramic acid, an essential element of the peptidoglycan cell wall.

This inhibitory action takes place at an earlier step than the action of β-lactams or glycopeptides.
