Mechanism of Action

• Fosfomycin (the active component of fosfomycin tromethamine) hasin vitroactivity against a broad range of gram-positive and gram-negative aerobic microorganisms which are associated with uncomplicated urinary tract infections. Fosfomycin is bactericidal in urine at therapeutic doses. The bactericidal action of fosfomycin is due to its inactivation of the enzyme enolpyruvyl transferase, thereby irreversibly blocking the condensation of uridine diphosphate-N-acetylglucosamine with p-enolpyruvate, one of the first steps in bacterial cell wall synthesis. It also reduces adherence of bacteria to uroepithelial cells.
• There is generally no cross-resistance between fosfomycin and other classes of antibacterial agents such as beta-lactams and aminoglycosides.
• Fosfomycin has been shown to be active against most strains of the following microorganisms, both in vitroand in clinical infections

• Aerobic gram-positive microorganisms
• Enterococcus faecalis
• Aerobic gram-negative microorganisms
• Escherichia coli
