Affected OrganismEnteric bacteria and other eubacteria
IndicationFor the treatment of uncomplicated urinary tract infections (acute cystitis) in women due to susceptible strains of <i>Escherichia coli</i> and <i>Enterococcus faecalis</i>.
PharmacologyFosfomycin is a broad spectrum antibiotic that concentrates in kidney and bladder and is used to treat uncomplicated urinary tract infections. Fosfomycin also reduces nephrotoxicity and ototoxicity of platinum-containing anti-tumor agents.
Mechanism of actionFosfomycin is a phosphoenolpyruvate analogue produced by Streptomyces that irreversibly inhibits enolpyruvate transferase (MurA), which prevents the formation of N-acetylmuramic acid, an essential element of the peptidoglycan cell wall.
