Methenamine is an antibacterial agent for preventing recurrent urinary tract infection. It can be used as methenamine hippurate or methenamine mandelate preparations and is United States Food and Drug Administration-approved. Methenamine exerts its activity because it is hydrolyzed to formaldehyde in acid urine.

Sample Use Guides

One tablet (1 g) twice daily for adults and children over 12 years of age. One-half tablet or one tablet (0.5 or 1 g) twice daily for children 6 to 12 years of age.
Route of Administration: Oral
In Vitro Use Guide
The antibacterial activity of methenamine and two of its organic acid salts was compared by continuous turbidimetric monitoring of static cultures exposed to the drugs and in an in vitro model of the treatment of bacterial cystitis. At pH 5.5, concentrations of 32 to 125 mg methenamine per 1 caused some inhibition of bacterial growth (Klebsiella aerogenes), but 250 to 500 mg/l were needed to suppress growth overnight. Methenamine hippurate was found to be less active than methenamine itself, whereas methenamine mandelate was as active as the parent compound.
