ATC code M04: ==M04A Antigout preparations==HyperuricemiaRasburicaseTophusAllopurinolAllopurinol hypersensitivity syndromeAllantoic acidArterial tortuosity syndrome: Arterial tortuosity syndrome (ATS) is a rare congenital connective tissue condition disorder characterized by elongation and generalized tortuosity of the major arteries including the aorta. It is associated with hyperextensible skin and hypermobility of joints, however symptoms vary depending on the patient.BenzbromaroneCalculus (dental): In dentistry, calculus or tartar is a form of hardened dental plaque. It is caused by precipitation of minerals from saliva and gingival crevicular fluid (GCF) in plaque on the teeth.EtamiphyllineRenal stone formation in space: Renal stone formation and passage during space flight can potentially pose a severe risk to crew member health and safety and could affect mission outcome. While the renal stones are routinely and successfully treated on Earth, the occurrence of these during space flight can prove to be problematic.Xanthine oxidase inhibitor: 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.OxypurinolCreatinineBiomarkers of aging: Biomarkers of aging are biomarkers that better predict functional capacity at a later age than chronological age. Stated another way, biomarkers of aging would give the true "biological age", which may be different from the chronological age.PurineAscorbic acidXanthinuriaHerniaria hirsuta: Herniaria hirsuta is a species of flowering plant in the pink family known by the common name hairy rupturewort. It is native to Eurasia and North Africa, and it is known on other continents, including North America, as an introduced species.Probenecid and colchicine: Probenecid with colchicine is a combination medication used to treat gout. Brand names include ColBenemid, Col-Probenecid, and Proben-C.Fructose malabsorptionOrganic anion-transporting polypeptide: An organic anion-transporting polypeptide (OATP) is a membrane transport protein or 'transporter' that mediates the transport of mainly organic anions across the cell membrane. Therefore OATPs are present in the lipid bilayer of the cell membrane, acting as the cell's gatekeepers.National Cholesterol Education Program: The National Cholesterol Education Program is a program managed by the National Heart, Lung and Blood Institute, a division of the National Institutes of Health. Its goal is to reduce increased cardiovascular disease rates due to hypercholesterolemia (elevated cholesterol levels) in the United States of America.Tumor lysis syndromeQRISK: QRISK2 (the most recent version of QRISK) is a prediction algorithm for cardiovascular disease (CVD) that uses traditional risk factors (age, systolic blood pressure, smoking status and ratio of total serum cholesterol to high-density lipoprotein cholesterol) together with body mass index, ethnicity, measures of deprivation, family history, chronic kidney disease, rheumatoid arthritis, atrial fibrillation, diabetes mellitus, and antihypertensive treatment.SulfinpyrazoneTroloxFishless cycling
