Fosfomycin trometamol is primarily used as an antibiotic to treat uncomplicated lower urinary tract infections, particularly those caused by susceptible strains of bacteria such as Escherichia coli and Enterococcus faecalis. It is often prescribed as a single-dose therapy, making it convenient for patients and improving adherence to treatment. The compound works by inhibiting bacterial cell wall synthesis, effectively stopping the growth and spread of the infection. Its high concentration in the urine ensures targeted action in the urinary tract. Fosfomycin trometamol is also valued for its low resistance rates, making it a reliable option in cases where other antibiotics may be less effective. Additionally, it is considered safe for use in pregnant women, further broadening its application in clinical settings.
