Allopurinol is a medication used to decrease high blood uric acid levels. [5] It is specifically used to prevent gout , prevent specific types of kidney stones and for the high uric acid levels that can occur with chemotherapy .
Clearance is therefore expressed as the plasma volume totally free of the drug per unit of time, and it is measured in units of volume per units of time. Clearance can be determined on an overall, organism level («systemic clearance») or at an organ level (hepatic clearance, renal clearance etc.). The equation that describes this concept is:
In these cases, clearance is almost synonymous with renal clearance or renal plasma clearance. Each substance has a specific clearance that depends on how the substance is handled by the nephron. Clearance is a function of 1) glomerular filtration , 2) secretion from the peritubular capillaries to the nephron , and 3) reabsorption from the ...
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. [1]
Drugs with other primary uses, that have known uricosuric properties, include losartan, [1] atorvastatin, and fenofibrate.Although these drugs may have significant uricosuric action, their other significant pharmacological actions in off-label use as a uricosuric requires careful assessment of the patient to achieve the most benefit and least risk.

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.
