Hexamethylene Tetramine
Hexamethylene Tetramine Uses, Dosage, Side Effects, Food Interaction and all others data.
Hexamethylene Tetramine is a heterocyclic organic compound with a cage-like structure similar to adamantane. In salt form it is used for the treatment of urinary tract infection (Example: methenamine hippurate which is the hippuric acid salt of methenamine).
Ingestion of a 1-gram dose of methenamine hippurate produces antibacterial activity in the urine within 1/2 hour. Administration of 1 g twice daily produces continuous antibacterial activity in the urine.

For prophylactic or suppressive treatment of frequently recurring urinary tract infections when long-term therapy is considered necessary. This drug is not used to treat infection and should only be used after appropriate eradication of infection with antimicrobial agents.
Hexamethylene Tetramine is also used to associated treatment for these conditions: Urinary Tract Infection
How Hexamethylene Tetramine works
Hexamethylene Tetramine does not have antibacterial properties in an alkaline environment (pH≥6); however, in a more acidic environment (pH<6), methenamine is hydrolyzed to formaldehyde. (1) Formaldehyde is considered to be highly bactericidal. (1) Formaldehyde has nonspecific antibacterial activity and works by denaturing proteins and nucleic acid of bacteria. (1) Certain bacteria such as Proteus sp. can alkalize urine, inhibiting the beneficial activity of formaldehyde. (1) The key role of the salt component of the drug, for example hippuric acid, is to maintain the acidic state of the urine. (1)

Elimination Route
After oral administration, rapid absorption of methenamine occurs. (1)
Half Life
Elimination half-life = 3-4 hours assuming normal renal function. (1)
Clearance
70-90% of a single oral dose of methenamine is excreted unchanged in the urine within 24 hours. (1)
Elimination Route
