Methenamine hippurate is a urinary antibacterial agent which releases formaldehyde and is excreted in the urine. Methenamine hippurate has a demonstrable activity in vitro at pH 5 to 6 against Escherichia coli, Staphylococcus aureus, Aerobacter aeroaenes, Pseudomonas aeruginosa and Proteus vulgaris, and a wide range of action against Klebsiella pneumoniae, Ps. aeruginosa, E. coli, Staph. aureus and Streptococcus haemolytic at pH of 7.4. This action is more effective than that of Methenamine alone, of Hippuric acid alone or of Sulphadiazine[1].
