🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is absorbed from the gastrointestinal tract after oral administration. The exact bioavailability is not established from the available information.
DistributionThis medicine distributes into body tissues, but specific volume of distribution data are not established from the available information.
Protein BindingNot established from the available information.
MetabolismThis medicine is metabolized in the liver, mainly to oxypurinol, which is also active. The exact metabolic pathways are not fully established from the available information.
Half-LifeThe elimination half-life of this medicine is not established from the available information. The active metabolite oxypurinol has a longer half-life and is renally excreted.
ExcretionThis medicine and its active metabolite oxypurinol are excreted mainly by the kidneys. Dose adjustment is needed in kidney disease.
BioavailabilityNot established from the available information.
Onset of ActionThe onset of uric acid lowering effect is gradual and may take days to weeks. Full effect may take several weeks to months.
Peak Plasma TimeNot established from the available information.
Duration of ActionThe uric acid lowering effect lasts as long as the medicine is taken regularly. The effect is not immediate and requires continuous use.

How It Works

This medicine works by inhibiting the enzyme xanthine oxidase. Xanthine oxidase is responsible for converting hypoxanthine to xanthine and then xanthine to uric acid. By blocking this enzyme, the medicine reduces the production of uric acid in the body. Lower uric acid levels help prevent gout attacks, uric acid deposits in joints and tissues, and uric acid kidney stones. The effect is not immediate and may take weeks to months to fully develop.

Mechanism Steps

1
Enzyme binding: This medicine binds to and inhibits the xanthine oxidase enzyme.
2
Blocked uric acid production: Inhibition of xanthine oxidase reduces the conversion of purines to uric acid.
3
Lower blood uric acid: As production falls, uric acid levels in the blood gradually decrease.
4
Crystal dissolution: Lower uric acid levels allow existing uric acid crystals in joints and tissues to dissolve over time.
5
Prevention of flares: With fewer crystals, the risk of recurrent gout attacks and kidney stones is reduced.
