Drug Interactions:

Drug interactions formaldehyde and sulfamethizole form an insoluble precipitate in acid urine; therefore, methenamine mandelate should not be administered concurrently with sulfamethizole or other sulfonamides. concurrent use of salicylates may lead to increased serum salicylate levels since excretion of salicylates is reduced in acidified urine.

Indications and Usage:

Indications and usage methenamine mandelate is indicated for the suppression or elimination of bacteriuria associated with pyelonephritis, cystitis, and other chronic urinary tract infections; also those neurologic diseases leading to an infected residual urine. when used as recommended, methenamine mandelate is particularly suitable for long-term therapy because of its safety and because resistance to the nonspecific bactericidal action of formaldehyde does not develop. pathogens resistant to other antibacterial agents may respond to methenamine mandelate because of the nonspecific effect of formaldehyde formed in an acid urine. prophylactic use rationale: urine is a good culture medium for many urinary pathogens. inoculation by a few organisms (relapse or reinfection) may lead to bacteriuria in susceptible individuals. thus, the rationale of management in recurring urinary tract infection (bacteriuria) is to change the urine from a growth-supporting to a growth-inhibiting medium. the
re is a growing body of evidence that long-term administration of methenamine mandelate can prevent the recurrence of bacteriuria in patients with chronic pyelonephritis. therapeutic use rationale : methenamine mandelate helps to sterilize the urine, and in some situations in which underlying pathologic conditions prevent sterilization by any means, it can help to suppress the bacteriuria. methenamine mandelate should not be used alone for acute infections with parenchymal involvement causing systemic symptoms such as chills and fever. a thorough diagnostic investigation as a part of the overall management of the urinary tract infection should accompany the use of methenamine mandelate.

Warnings:

Warnings methenamine mandelate should be avoided in patients with gout because it may precipitate urate crystals in their urine. a similar situation may arise in patients with a predisposition to the formation of uric acid stones. methenamine preparations should not be given to patients taking sulfonamides because some sulfonamides may form an insoluble precipitate with formaldehyde in the urine.

General Precautions:

General dysuria may occur (usually at higher than recommended dosage). this can be controlled by reducing the dosage and the acidification. when urine acidification is contraindicated or unattainable (as with some urea-splitting bacteria), the drug is not recommended. large doses of methenamine (8 g daily for 3 to 4 weeks) have caused bladder irritation, painful and frequent micturition, albuminuria, and gross hematuria.

Dosage and Administration:

Dosage and administration the average adult dose is 4 g a day given as one 1000 mg tablet or two 500 mg tablets after each meal and at bedtime. children 6 to 12 years of age should receive half the adult dose; one 500 mg tablet, 4 times a day.

Contraindications:

Contraindications methenamine mandelate tablets are contraindicated in patients with renal insufficiency, severe hepatic disease, severe dehydration, and in patients who have exhibited hypersensitivity to any components of this product.

Adverse Reactions:

Adverse reactions gastrointestinal disturbances (nausea, stomach upset), generalized skin rash, dysuria, painful or difficult urination may occur occasionally with the use of methenamine preparations. microscopic and rarely, gross hematuria have been described.

Drug Interactions:

Drug interactions formaldehyde and sulfamethizole form an insoluble precipitate in acid urine; therefore, methenamine mandelate should not be administered concurrently with sulfamethizole or other sulfonamides. concurrent use of salicylates may lead to increased serum salicylate levels since excretion of salicylates is reduced in acidified urine.

Use in Pregnancy:

Pregnancy teratogenic effects. pregnancy category c. animal reproduction studies have not been conducted with methenamine mandelate. it is also not known whether methenamine mandelate can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. since methenamine is known to cross the placental barrier, methenamine mandelate should be given to a pregnant woman only if the potential benefit outweighs the risk.

Description:

Description methenamine mandelate, a urinary antibacterial agent, is the chemical combination of mandelic acid with methenamine. methenamine mandelate is available for oral use as film-coated tablets. methenamine mandelate tablets contain 500 mg and 1000 mg (1 g) methenamine mandelate and the following inactive ingredients: croscarmellose sodium, fd&c blue #2 aluminum lake, magnesium stearate, microcrystalline cellulose, polyethylene glycol, polyvinyl alcohol, silicon dioxide, talc and titanium dioxide.

Clinical Pharmacology:

Clinical pharmacology methenamine mandelate is readily absorbed but remains essentially inactive until it is excreted by the kidneys and concentrated in the urine. an acid urine is essential for antibacterial action, with maximum efficacy occurring at ph 5.5 or less. in an acid urine, mandelic acid exerts its antibacterial action and also contributes to the acidification of the urine. mandelic acid is excreted both by glomerular filtration and tubular excretion. the methenamine component is hydrolyzed in acid urine to ammonia and to the bactericidal agent formaldehyde. proportionally less formaldehyde is released as urinary ph approaches 6.0 and insufficient quantities are released above this level for therapeutic response. there is equally effective antibacterial activity against both gram-positive and gram-negative organisms, since the antibacterial action of mandelic acid and formaldehyde is nonspecific. there are reports that methenamine mandelate is ineffective in some infections
with proteus vulgaris and urea-splitting strains of pseudomonas aeruginosa and a. aerogenes . since urea-splitting strains may raise the ph of the urine, particular attention to supplementary acidification with agents such as ascorbic acid, and urinary ph monitoring is required. however, results in any single case will depend to a large extent on the underlying pathology and the overall management.

Carcinogenesis and Mutagenesis and Impairment of Fertility:

Carcinogenesis and mutagenesis methenamine mandelate has not been evaluated for carcinogenicity or mutagenicity. methenamine was evaluated for mutagenicity in the ames salmonella/mammalian microsome test. five strains of salmonella typhimurium (ta98, ta100, ta1535, ta1537 and ta1538) and a strain of escherichia coli (wp2uvra) were used. at a dose of 10,000 μg/plate methenamine showed mutagenic activity in salmonella typhimurium ta98 and ta100 by metabolic activation and also showed mutagenic activity in ta98 without microsomal activation. in one large study, no evidence of carcinogenicity was found following long-term oral administration of methenamine 1.25 g/kg/day to rats (104 weeks) and mice (60 weeks).
