Acetohydroxamic acid is indicated in the prophylaxis of struvite calculi formation that is promoted by urease-producing bacteria such as Proteus. Its use may enhance effectiveness of urinary antibacterials, especially following surgical removal of existing stones. Use of acetohydroxamic acid also improves the possibility of reducing the frequency and rate of new stone formation. /Included in US product labeling/

Acetohydroxamic acid is indicated as an adjunct in the treatment of chronic, urea-splitting urinary tract infections caused by urease-producing bacteria. Its inhibition of urease activity decreases the urinary ammonia and alkalinity produced from the enzyme hydrolysis of urea. /Included in US product labeling/

Acetohydroxamic acid is not indicated for dissolution of existing calculi, replacement of indicated surgical treatment, urinary tract infections controllable by culture-specific oral antibacterials, or urinary tract infections caused by nonurease producing organisms.

Use of acetohydroxamic acid is contraindicated during pregnancy since studies in animals have shown it to cause leg deformities at doses of 750 mg/kg of body weight and above. At doses of 1500 mg/kg, exencephaly and encephalocele occurred. Also, cardiac, coccygeal, and abdominal-wall anomalies developed in pups of beagle dogs given 25 mg/kg a day during pregnancy.

It is not known if acetohydroxamic acid is distributed into breast milk. Although problems in humans have not been documented, its use is not recommended in breast-feeding mothers because of the potential for serious adverse effects in the nursing infant.

Headache, appearing during the first 48 hours of treatment, reportedly occurs in approximately 30% of patients receiving acetohydroxamic acid; however, several clinicians reported that mild, transient headache occurred in 70-75% of patients during initiation of therapy. Headache is generally mild, responsive to oral salicylate analgesics, and usually disappears spontaneously. Headache has not been associated with vertigo, tinnitus, or visual or auditory disturbances. Malaise occurs in about 20-25% of patients receiving the drug.

Used, in addition to antibiotics or medical procedures, to treat chronic urea-splitting urinary infections.
Acetohydroxamic Acid, a synthetic drug derived from hydroxylamine and ethyl acetate, is similar in structure to urea. In the urine, it acts as an antagonist of the bacterial enzyme urease. Acetohydroxamic Acid has no direct antimicrobial action and does not acidify urine directly.
Enzyme Inhibitors
Compounds or agents that combine with an enzyme in such a manner as to prevent the normal substrate-enzyme combination and the catalytic reaction. (See all compounds classified as Enzyme Inhibitors.)

In rodents, about 55% of an intraperitoneal dose is excreted in urine as unchanged drug, 15% as acetamide, and 10% as acetate within 24 hours; approximately 7% of the dose is excreted by the lungs as carbon dioxide and less than 1% is excreted in feces within 24 hours.

Acetohydroxamic Acid reversibly inhibits the bacterial enzyme urease. This inhibits the hydrolysis of urea and production of ammonia in urine infected with urea-splitting organisms, leading to a decrease in pH and ammonia levels. As antimicrobial agents are more effective in such conditions, the effectiveness of these agents is amplified, resulting in a higher cure rate.
Inhibits the hydrolysis of urea and production of ammonia in urine infected with urea-splitting bacteria, by reversible inhibition of the bacterial enzyme urease, and by the chelation of nickel, an essential component of urease enzymes. Such enzyme inhibition results in reduction of both urine alkalinity and ammonia concentration. The effectiveness of antibacterial medication is then enhanced and the formation of urinary calculi reduced.
