Fosfural
Fosfural is an antibacterial agent containing fosfomycin. It is a broad-spectrum antibiotic that works by disrupting the synthesis of the bacterial cell wall, which leads to cell death. It is highly concentrated in the kidneys and bladder, making it exceptionally effective for urinary tract infections.
