🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionAllopurinol is absorbed from the gastrointestinal tract. The exact bioavailability is not established from the available information.
DistributionAllopurinol is distributed widely in body tissues, but specific distribution data are not established from the available information.
Protein BindingAllopurinol is approximately 20% bound to plasma proteins, but this value may vary. Not established from the available information.
MetabolismAllopurinol is metabolized in the liver to oxypurinol, which is also pharmacologically active. Oxypurinol is primarily responsible for the prolonged duration of action.
Half-LifeThe elimination half-life of allopurinol is approximately 1 to 2 hours, while its active metabolite oxypurinol has a longer half-life of approximately 15 to 20 hours. These values may vary in renal impairment.
ExcretionAllopurinol and its metabolites are excreted primarily in the urine. Renal excretion is the major route of elimination.
BioavailabilityThe bioavailability of allopurinol is approximately 80%, but this may vary. Not established from the available information.
Onset of ActionThe onset of uric acid-lowering effect may take several days to weeks. The full therapeutic effect for gout prevention may take several weeks to months.
Peak Plasma TimePeak plasma concentrations of allopurinol are reached approximately 1.5 to 2 hours after oral administration. The peak of oxypurinol occurs later.
Duration of ActionThe uric acid-lowering effect persists for approximately 24 hours or more due to the active metabolite oxypurinol.

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, allopurinol reduces the production of uric acid in the body. Lower uric acid levels help prevent the formation of uric acid crystals in joints and kidneys, which are responsible for gout attacks and kidney stones. This medicine does not relieve pain or inflammation during an acute gout attack; it is used to prevent future attacks by maintaining low uric acid levels.

Mechanism Steps

1
Inhibition of xanthine oxidase: This medicine binds to and inhibits the enzyme xanthine oxidase, blocking the conversion of hypoxanthine and xanthine to uric acid.
2
Reduced uric acid production: As a result of enzyme inhibition, less uric acid is produced in the body, leading to lower serum uric acid levels.
3
Prevention of crystal formation: Lower uric acid levels reduce the likelihood of uric acid crystals forming in joints and kidneys, thereby preventing gout attacks and kidney stones.
4
Gradual clinical improvement: Over time, consistent use reduces the frequency and severity of gout flares and prevents uric acid stone recurrence.
