🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is absorbed from the gastrointestinal tract. The exact bioavailability is not established from the available information.
DistributionThis medicine is distributed widely throughout the body, including into the liver, kidneys, and joints. It crosses the blood-brain barrier to some extent. The volume of distribution is not established from the available information.
Protein BindingThis medicine is approximately 20% bound to plasma proteins. The exact binding characteristics are not established from the available information.
MetabolismThis medicine is metabolized in the liver to oxypurinol, which is also pharmacologically active. Oxypurinol is primarily responsible for the long duration of action of this medicine.
Half-LifeThe elimination half-life of this medicine is approximately 1 to 2 hours, while its active metabolite oxypurinol has a half-life of approximately 15 to 20 hours. The exact values may vary based on individual factors.
ExcretionThis medicine and its metabolites are primarily excreted by the kidneys. About 70% of a dose is excreted in the urine as oxypurinol. Renal impairment can prolong the elimination of oxypurinol.
BioavailabilityThe bioavailability of this medicine is approximately 80% when taken orally. The exact value may vary.
Onset of ActionThe onset of action for lowering uric acid levels is gradual, typically taking 1 to 2 weeks to observe a significant reduction. The full effect may take several weeks.
Peak Plasma TimeThe peak plasma time for this medicine is approximately 1.5 to 2 hours after oral administration. The peak for oxypurinol occurs later, around 4 to 6 hours.
Duration of ActionThe duration of action is prolonged due to the active metabolite oxypurinol, which has a long half-life. The uric acid-lowering effect lasts for approximately 24 hours or more after a single dose.

How It Works

This medicine works by inhibiting the enzyme xanthine oxidase. Xanthine oxidase is responsible for converting hypoxanthine to xanthine and then to uric acid. By blocking this enzyme, this medicine reduces the production of uric acid in the body. This leads to lower blood uric acid levels, which helps prevent the formation of uric acid crystals in joints and kidneys. These crystals are responsible for the pain and inflammation seen in gout. This medicine does not relieve pain during an acute gout attack; it is used to prevent future attacks.

Mechanism Steps

1
Inhibition of xanthine oxidase: This medicine binds to and inhibits the enzyme xanthine oxidase, blocking the conversion of hypoxanthine to xanthine and xanthine to uric acid.
2
Reduced uric acid production: As a result of enzyme inhibition, the production of uric acid in the body is decreased.
3
Lower serum uric acid levels: With less uric acid being produced, blood levels of uric acid gradually decrease.
4
Prevention of crystal formation: Lower uric acid levels prevent the formation and deposition of uric acid crystals in joints and kidneys, reducing gout attacks and kidney stones.
