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 ...
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 ...
Routes of administration are usually classified by application location (or exposition). The route or course the active substance takes from application location to the location where it has its target effect is usually rather a matter of pharmacokinetics (concerning the processes of uptake, distribution, and elimination of drugs).
Lesinurad/allopurinol (trade name Duzallo) is a fixed-dose combination drug for the treatment of gout. [1] It contains 200 mg of lesinurad and 300 mg of allopurinol.In August 2017, the US Food and Drug Administration approved it for the treatment of hyperuricemia associated with gout in patients for whom target serum uric acid levels have not been achieved with allopurinol alone.

The most pronounced effects on height have been seen in children experiencing the onset of puberty before 6 years of age; however there is variability in height outcomes across studies which can be attributed to varying study designs, time of symptom presentation, and time of treatment termination.

The BNF for Children developed from the British National Formulary (BNF), which prior to 2005 had provided information on the treatment of children, with the doses largely determined by calculations based on the body weight of the child. The guidance was provided by pharmacists and doctors whose expertise was in the care of adults.
Febuxostat is used to treat chronic gout and hyperuricemia. [12] Febuxostat is typically recommended only for people who cannot tolerate allopurinol. [13] National Institute for Health and Clinical Excellence concluded that febuxostat is more effective than standard doses of allopurinol, but not more effective than higher doses of allopurinol.
Oxipurinol (INN, or oxypurinol USAN) is an inhibitor of xanthine oxidase. [1] It is an active metabolite of allopurinol and it is cleared renally. [2] In cases of renal disease, this metabolite will accumulate to toxic levels.
