Pharmacological inhibition of uric acid synthesis This product is a drug. Allopurinol and its metabolites oxygen allopurinol inhibited xanthine oxidase, hypoxanthine and xanthine prevent uric acid metabolism, thereby reducing the production of uric acid. The blood and urine levels of uric acid solubility is reduced to the following levels, prevent the formation of crystals of uric acid is deposited in the joints and other tissues, but also help patients with gout uric acid crystals within the organization to re-dissolve. New purine synthesis in vivo inhibition of guanine nucleic acid phosphatase converting enzymes - allopurinol also by hypoxanthine. This product is 24 hours after oral administration of serum uric acid concentration began to decline, and in 2 to 4 weeks and it decreased significantly. Acute toxicity test results: oral LD50 in rats of 6000mg / kg, intraperitoneal injection of LD50 of 750mg / kg; mouse oral LD50 of 700mg / kg, intraperitoneal injection of LD50 of 160mg / kg. Pharma-cokinetics: This product is completely absorbed after oral administration, from 2 to 6 hours up to the peak plasma concentration in the gastrointestinal tract, liver metabolism in active oxygen allopurinol, both of which can not be bound to plasma proteins. Half-life of this product is 14 to 28 hours, and oxygen allopurinol by the kidneys. With uricosuric drugs can promote oxygen allopurinol excretion, renal insufficiency but reduce their emissions.
