Allopurinol, sold under the brand name Zyloprim among others, is a medication used to decrease high blood uric acid levels. [12][13] Cotherapy has also been shown to greatly improve hepatoxicity side effects in treatment of IBD. [33] Allopurinol was marketed at the time by Burroughs-Wellcome. Allopurinol is a classified as a xanthine oxidase inhibitor. [23][24] As of 2011 the FDA-approved drug label for allopurinol did not contain any information regarding the HLA-B*5801 allele, though FDA scientists did publish a study in 2011 which reported a strong, reproducible and consistent association between the allele and allopurinol-induced SJS and TEN. Another side effect of allopurinol is interstitial nephritis. The enzyme is present in two forms, one with dehydrogenase activity (xanthine dehydrogenase) and the other with oxidase activity. [16] Second, some people are hypersensitive to the drug, therefore its use requires careful monitoring. [32] Allopurinol was first marketed as a treatment for gout in 1966. Echocardiographic and hemodynamic assessments were performed in vivo. The most serious adverse effect is a hypersensitivity syndrome consisting of fever, skin rash, eosinophilia, hepatitis, and worsened renal function. [10] Intravenous formulations are used in this indication when people cannot take medicine by mouth.

For research use only. A high uric acid level can cause gout or gouty arthritis (joint pain and inflammation). Xanthine oxidase ñ allopurinol for gout: Xanthine oxidase is the last enzyme on the breakdown pathway of purine bases in primates and it catalyses the conversion of hypoxanthine to xanthine and of xanthine to uric acid. Xanthine oxidase inhibitors are primarily used in the clinical prevention and treatment of gout associated with hyperuricemia. 2018 Aug;36(4):e12432. [4], Common side effects when used by mouth include itchiness and rash. While xanthine cannot be converted to purine ribotides, hypoxanthine can be salvaged to the purine ribotides adenosine and guanosine monophosphates. Eur J Heart Fail. [4] It is on the World Health Organization's List of Essential Medicines, the safest and most effective medicines needed in a health system. [14] Cotherapy invariably requires dose reduction of the thiopurine, usually to one-third of the standard dose depending upon the patient's genetic status for thiopurine methyltransferase. These results indicated that allopurinol was hydroxylated to oxipurinol mainly by the enzyme which is not identical to xanthine oxidase in vivo. [3][4] It is taken by mouth or injected into a vein. 1998;98:946–952. 400 mg of allopurinol was administered to a patient with xanthine oxidase deficiency, and plasma allopurinol, oxipurinol, hypoxanthine, and xanthine levels were determined serially by the use of high-performance liquid … 9H-xanthine is an oxopurine in which the purine ring is substituted by oxo groups at positions 2 and 6 and N-9 is protonated. 2020 May 12;21(10):3405. doi: 10.3390/ijms21103405. … [23][24] The frequency of the HLA-B*5801 allele varies between ethnicities: Han Chinese and Thai populations have HLA-B*5801 allele frequencies of around 8%, as compared to European and Japanese populations, who have allele frequencies of around 1.0% and 0.5%, respectively. In the majority of patients with gout, the mainstay of treatment for decreasing serum uric acid concentrations has been with inhibitors of xanthine oxidase (XO), such as allopurinol (Zyloprim; Aloprim) and febuxostat (Uloric) along with changes in diet and lifestyle, to … A through D, Representative Western blot analysis…, Current‐voltage (I–V) curve for IC aL density obtained using patch clamping (C). Summary:. | Probucol prevents atrial ion channel remodeling in an alloxan-induced diabetes rabbit model. Compared with the control group, rabbits with DM showed left ventricular hypertrophy, increased atrial interstitial fibrosis, oxidative stress and fibrosis markers, ICaL and intracellular calcium transient, and atrial fibrillation inducibility. This medicine is available only with your doctor's prescription. Today it is used in gout and hyperuricemia. Xanthine oxidase (XO) is a key enzyme in reactive oxygen species formation. Xanthine oxidase, the enzyme inhibited by allopurinol and febuxostat to therapeutic effect in the management of gout, is involved in the catabolism of azathioprine. 2014;32:233–241. Probucol prevents atrial remodeling by inhibiting oxidative stress and TNF-α/NF-κB/TGF-β signal transduction pathway in alloxan-induced diabetic rabbits. [2] Xanthine oxidase is responsible for the successive oxidation of hypoxanthine and xanthine, resulting in the production of uric acid, the product of human purine metabolism. The archetypal xanthine oxidase inhibitor, Allopurinol has been shown to have other beneficial effects such as a reduction in vascular reactive oxygen species and mechano-energetic uncoupling. Epub 2009 Apr 8. Front Physiol. Abstract. [25] The increase in risk for developing allopurinol-induced SJS or TEN in individuals with the HLA-B*5801 allele (as compared to those who do not have this allele) is very high, ranging from a 40-fold to a 580-fold increase in risk, depending on ethnicity.

Xanthine oxidase inhibitor allopurinol improves atrial electrical remodeling in diabetic rats by inhibiting CaMKII/NCX signaling. HHS -, Zhang Q, Liu T, Ng CY, Li G. Diabetes mellitus and atrial remodeling: mechanisms and potential upstream therapies. It has been suggested that the causal link of this association is increased xanthine oxidase (XO)–derived oxygen free radical production and endothelial dysfunction. Because the inhibition of XO limits the formation of radical oxygen species as well as uric acid (UA) production, allopurinol has been used experimentally for the treatment of conditions associated with ischemia and reperfusion (I/R) injury. Allopurinol is known chemically as 1,5-dihydro-4H-pyrazolo [3,4-d] pyrimidin-4-one. For this reason, oxipurinol is believed responsible for the majority of allopurinol's effect. It is a tautomer of a 7H-xanthine. Background: Xanthine oxidase is a flavoprotein that contains molybdenum, nonheme iron, and labile sulfur. A patient with complete deficiency of xanthine oxidase would not be expected to oxidase allopurinol to oxipurinol if allopurinol did not have any alternative metabolic pathway. Impact of atrial fibrillation on mortality in patients with chronic heart failure. There are several mechanisms, including inflammation, oxidative stress and abnormal calcium homeostasis, involved in the pathogenesis of atrial fibrillation. Protected by copyright. Allopurinol is almost completely metabolized to oxipurinol within two hours of oral administration, whereas oxipurinol is slowly excreted by the kidneys over 18–30 hours. Concomitant use of xanthine oxidase inhibitors and azathioprine may result in profound myelosuppression and should be avoided. For this reason, oxipurinol is believed responsible for the majority of allopurinol's effect. The latter is normally excreted, although quantities of the other purines may also find their way into the urine. [17], More rarely, allopurinol can also result in the depression of bone marrow elements, leading to cytopenias, as well as aplastic anemia. Distribution. 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 levels occur either spontaneously, or after cytotoxic therapy; certain enzyme disorders which lead to overproduction of urate, for example: hypoxanthine-guanine phosphoribosyltransferase, including Lesch–Nyhan syndrome; glucose 6-phosphatase including glycogen storage disease; phosphoribosyl pyrophosphate synthetase, phosphoribosyl pyrophosphate amidotransferase; adenine phosphoribosyltransferase. | [34], InChI=1S/C5H4N4O/c10-5-3-1-8-9-4(3)6-2-7-5/h1-2H,(H2,6,7,8,9,10), World Health Organization's List of Essential Medicines, hypoxanthine-guanine phosphoribosyltransferase, phosphoribosyl pyrophosphate amidotransferase, medicines that increase the secretion of uric acid, Clinical Pharmacogenetics Implementation Consortium, "Therapeutic effects of xanthine oxidase inhibitors: renaissance half a century after the discovery of allopurinol", "Optimizing 6-mercaptopurine and azathioprine therapy in the management of inflammatory bowel disease", "Azathioprine co-therapy with allopurinol for inflammatory bowel disease: trials and tribulations", "Uric Acid-Lowering Drugs Pathway, Pharmacodynamics", "Allopurinol pharmacogenetics: assessment of potential clinical usefulness", "2012 American College of Rheumatology guidelines for management of gout.
