Pharmacodynamics and pharmacokinetics
The principle of action is based on the inhibition of xanthine oxidase, preventing the process of transition of hypoxanthine to xanthine, from which uric acid is formed. The drug reduces the concentration of salts of uric acid, uric acid itself in liquid media in the human body.
The drug prevents the formation of urate deposits in the renal system, in the tissues of the body, facilitates their dissolution. Allopurinol by reducing the transformation of hypoxanthine to xanthine leads to their enhanced use in the process of synthesizing nucleotides into nucleic acids. With the accumulation of xanthines in the plasma, the normal exchange of nucleic acids does not change, the precipitation process is not disturbed, and xanthines do not precipitate in the plasma, due to their high solubility. With the excretion of xanthines with urine, the risk of nephrourolythiasis does not increase.

Urikozuric medicines increase the renal clearance of the active metabolite oxypurinol, in contrast to thiazide diuretics, which increase toxicity and slow kidney clearance.
Allopurinol enhances the effect of hypoglycemic, oral agents. The drug inhibits metabolism, increases the concentration, and accordingly, the toxicity of methotrexate, mercaptopurine, azathioprine, xanthines, adenine arabinoside. When taking acetylsalicylic acid and colchicine, the effectiveness of the drug increases. Allopurinol prolongs the half-life of coumarin anticoagulants, which leads to an increase in the hypoprothrombinemic effect.
