Allopurinol half life

Allopurinol has a plasma half-life of about 1 to 2 hours. Oxipurinol is a less potent inhibitor of xanthine oxidase than allopurinol, but the

by WY Chu Cited by 11The half-life of allopurinol is 1–2 h, whereas oxypurinol has a half-life of 25–30 h [20,21,22]. As a result, although allopurinol and

Allopurinol is metabolized in the liver and has a 1 3 hour half-life, while oxypurinol is excreted in the urine and has a 12 17 hour half-life. Therefore, allopurinol can be dosed once daily, with lower dosage requirements in patients with renal insufficiency, as the half-life of oxypurinol increases as the creatinine clearance decreases.

Following one oral dose of 300 mg of allopurinol, maximum plasma levels of about 3 mcg/mL of allopurinol and 6.5 mcg/mL of oxipurinol were measured . Half Life The plasma half-life of allopurinol is 1-2 hours, due to its rapid renal clearance .

Allopurinol: Mechanism of Action and Safety. Allopurinol has an oral bioavailability of approximately 80% . It has a half-life of one hour, however, the half-life of the active metabolite oxypurinol is much longer at 23 h. Allopurinol is predominately excreted by the kidneys as its active metabolite oxypurinol . Xanthine oxidoreductase
