Hipeksal Uses, Dosage, Side Effects, Food Interaction and all others data.

Hipeksal 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.

Hipeksal is also used to associated treatment for these conditions: Urinary Tract Infection

How Hipeksal works

Hipeksal 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)

Toxicity

Less than 3.5% of patients treated with this drug will experience minor adverse events such as upset stomach, dysuria, nausea, and rash.

Food Interaction

  • Take with food.

Hipeksal Disease Interaction

Major: crystalluria, gout, liver disease

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
