Allopurinol is used to reduce urate formation in conditions where urate deposition has already occurred or is predictable. The specific diseases and conditions where it is used include gouty arthritis, skin tophi, kidney stones, idiopathic gout; uric acid lithiasis; acute uric acid nephropathy; neoplastic disease and myeloproliferative disease with high cell turnover rates, in which high urate ...
During a gout flare-up, you have acute gout symptoms, such as intense pain and swelling in an affected joint. ... According to the American College of Rheumatology guidelines, allopurinol is the ...
Gout presenting as slight redness in the metatarsophalangeal joint of the big toe. Gout can present in several ways, although the most common is a recurrent attack of acute inflammatory arthritis (a red, tender, hot, swollen joint). [4] The metatarsophalangeal joint at the base of the big toe is affected most often, accounting for half of cases ...
Unless high blood levels of uric acid are determined in a clinical laboratory, hyperuricemia may not cause noticeable symptoms in most people. [4] Development of gout – which is a painful, short-term disorder – is the most common consequence of hyperuricemia, which causes deposition of uric acid crystals usually in joints of the extremities, but may also induce formation of kidney stones ...
A xanthine oxidase inhibitor is any substance that inhibits the activity of xanthine oxidase, an enzyme involved in purine metabolism.In humans, inhibition of xanthine oxidase reduces the production of uric acid, and several medications that inhibit xanthine oxidase are indicated for treatment of hyperuricemia and related medical conditions including gout.

Allopurinol hypersensitivity syndrome (AHS) typically occurs in persons with preexisting kidney failure. [3]: 119 Weeks to months after allopurinol is begun, the patient develops a morbilliform eruption [3]: 119 or, less commonly, develops one of the far more serious and potentially lethal severe cutaneous adverse reactions viz., the DRESS syndrome, Stevens Johnson syndrome, or toxic epidermal ...
There is preliminary evidence that daily colchicine may be effective as a long-term prophylaxis when used with allopurinol to reduce the risk of increased uric acid levels and acute gout flares; [27] adverse gastrointestinal effects may occur, [28] though overall the risk of serious side effects is low. [29] [30]
Medications that may contribute to the cure or amelioration of hyperuricosuria include allopurinol which acts by inhibiting xanthine oxidase and reducing uric acid production. [2] Hyperuricosuria may be a medical sign of: Gout (very common) Kidney stones of uric acid (uric acid nephrolithiasis) Acute uric acid nephropathy; Acute kidney failure
