Used as an antibiotic to treat bacterial infections, particularly urinary tract infections caused by susceptible strains of Escherichia coli and Enterococcus faecalis. It is effective in both uncomplicated and complicated UTIs due to its broad-spectrum activity and ability to penetrate well into urinary tissues. Fosfomycin disodium salt is administered orally or intravenously, depending on the formulation, and is especially valuable in cases involving multidrug-resistant bacteria. Its unique mechanism of action—blocking bacterial cell wall synthesis early by inhibiting the enzyme MurA—makes it useful in treating infections resistant to other antibiotics like beta-lactams or fluoroquinolones. It is also used in prophylactic regimens before urological procedures.
