Allopurinol Usage And Synthesis
Chemical PropertiesWhite to Off-White Solid
Usesantihyperuricemia, antigout, antiurolithic
UsesXanthine oxidase inhibitor; decreases uric acid production. Used in treatment of hyperuricemia and chronic gout. Antiurolithic
IndicationsAllopurinol (Zyloprim) is the drug of choice in the treatment of chronic tophaceous gout and is especially useful in patients whose treatment is complicated by renal insufficiency.
Brand nameLopurin (Abbott); Lopurin (BASF); Zyloprim (Promethus).
General DescriptionOdorless tasteless white microcrystalline powder.
Air & Water ReactionsInsoluble in water.
Reactivity ProfileAllopurinol is an aminoalcohol. Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides. Allopurinol darkens above 572° F, and at an indefinite high temperature, Allopurinol chars and decomposes. At 221° F, maximum stability occurs at pH 3.1- 3.4. Allopurinol decomposes in acidic and basic solutions.
Fire HazardFlash point data for Allopurinol are not available; however, Allopurinol is probably combustible.
Mechanism of actionAllopurinol, in contrast to the uricosuric drugs, reduces serum urate levels through a competitive inhibition of uric acid synthesis rather than by impairing renal urate reabsorption. This action is accomplished by inhibiting xanthine oxidase, the enzyme involved in the metabolism of hypoxanthine and xanthine to uric acid. After enzyme inhibition, the urinary and blood concentrations of uric acid are greatly reduced and there is a simultaneous increase in the excretion of the more soluble uric acid precursors, xanthine and hypoxanthine.
Allopurinol itself is metabolized by xanthine oxidase to form the active metabolite oxypurinol, which tends to accumulate after chronic administration of the parent drug.This phenomenon contributes to the therapeutic effectiveness of allopurinol in long-term use. Oxypurinol is probably responsible for the antigout effects of allopurinol. Oxypurinol itself is not administered because it is not well absorbed orally.
Clinical UseAllopurinol is especially indicated in the treatment of chronic tophaceous gout, since patients receiving it show a pronounced decrease in their serum and urinary uric acid levels. Because it does not depend on renal mechanisms for its efficacy, allopurinol is particularly beneficial for patients who already have developed renal uric acid stones, patients with excessively high urate excretion (e.g., above 1,200 mg in 24 hours), patients with a variety of blood disorders (e.g., leukemia, polycythemia vera), patients with excessive tophus deposition, and patients who fail to respond well to the uricosuric drugs.
Allopurinol also inhibits reperfusion injury. This injury occurs when organs that either have been transplanted or have had their usual blood perfusion blocked are reperfused with blood or an appropriate buffer solution. The cause of this injury is local formation of free radicals, such as the superoxide anion, the hydroxyl free radical, or peroxynitrite. These substances are strong oxidants and are quite damaging to tissues.
Side effectsCommon toxicities associated with allopurinol administration include a variety of skin rashes, gastrointestinal upset, hepatotoxicity, and fever. These reactions are often sufficiently severe to dictate termination of drug therapy. It is advised that therapy not be initiated during an acute attack of gouty arthritis. As with the uricosuric drugs, therapy with allopurinol should be accompanied both by a sufficient increase in fluid intake to ensure water diuresis and by alkalinization of the urine. Prophylactic use of colchicine also helps to prevent acute attacks of gout that may be brought on during the initial period of allopurinol ingestion.
Safety ProfileHuman poison by ingestion. Poison experimentally by intraperitoneal and subcutaneous routes. An experimental teratogen. Human systemic effects by ingestion: blood leukopenia, dermatitis, jaundice, muscle weakness, thrombocytopenia. When heated to decomposition it emits toxic fumes of NOx. An FDA proprietary drug used as a xanthine oxidase inhibitor.
Veterinary Drugs and TreatmentsThe principle veterinary uses for allopurinol are for the prophylactic treatment of recurrent uric acid uroliths and hyperuricosuric calcium oxalate uroliths in small animals. It has also been used in an attempt to treat gout in pet birds and reptiles.
Allopurinol has been recommended as an alternative treatment for canine Leishmaniasis. Although it appears to have clinical efficacy, it does not apparently clear the parasite in most dogs at usual dosages. Allopurinol may also be useful for American Trypanosomiasis.
PrecautionsSince allopurinol is metabolized by the hepatic microsomaldrug-metabolizing enzymes, coadministration ofdrugs also metabolized by this system should be donewith caution. Because allopurinol inhibits the oxidationof mercaptopurine and azathioprine, their individualadministered doses must be decreased by as much as75% when they are given together with allopurinol.Allopurinol may also increase the toxicity of other cytotoxicdrugs (e.g., vidarabine). The actions of allopurinolare not antagonized by the coadministration of salicylates.
