Methenamine hippurate

Methenamine hippurate is a broad-spectrum Antibacterial (urinary).

Under acidic conditions, methenamine hippurate is hydrolyzed to formaldehyde and ammonia, which exerts an antibacterial effect. It is effective against a wide range of bacteria but lacks activity against Proteus and other bacteria that increase urine alkalinity. Formulations containing methenamine hippurate have been used to treat urinary tract infections.
