Allopurinol and oxypurinol promote osteoblast differentiation and increase bone formation [PDF]
Experimental Cell Research, 2016 Allopurinol and its active metabolite, oxypurinol are widely used in the treatment of gout and hyperuricemia. They inhibit xanthine oxidase (XO) an enzyme in the purine degradation pathway that converts xanthine to uric acid.

The impact of peritoneal dialysis on oxypurinol and urate elimination in people with gout
NephrologyAbstract Gout affects 15%–30% of individuals with advanced kidney disease. Allopurinol which is rapidly and extensively metabolised to an active metabolite, oxypurinol, is the most commonly prescribed urate‐lowering therapy. Oxypurinol is almost entirely eliminated by the kidneys (>95%) and has an elimination half‐life of 18–30 h in those with normal ...

Effect of Oxypurinol on Renal Reperfusion Injury in the Rat
Renal Failure, 1993 Oxygen-based free radicals produced by the enzyme xanthine oxidase may be involved in postischemic reperfusion injury. To determine whether oxypurinol, a xanthine oxidase inhibitor and the major metabolite of allopurinol, attenuates renal ischemic reperfusion injury, and, if so, to determine its most effective dose, oxypurinol 2.5, 5, 10 or 20 mg/kg BW

An allopurinol adherence tool using plasma oxypurinol concentrations
British Journal of Clinical Pharmacology, 2022AbstractAimsThis study aimed to develop and evaluate an allopurinol adherence tool based on steady‐state oxypurinol plasma concentrations, allopurinol's active metabolite.MethodsPlasma oxypurinol concentrations were simulated stochastically from an oxypurinol pharmacokinetic model for allopurinol doses of 100‐800 mg daily, accounting for differences in

Oxidative and nitrosative stress in acute pancreatitis. Modulation by pentoxifylline and oxypurinol
Biochemical Pharmacology, 2012 Item does not contain fulltextReactive oxygen species are considered mediators of the inflammatory response and tissue damage in acute pancreatitis. We previously found that the combined treatment with oxypurinol - as inhibitor of xanthine oxidase- and ...

Oxypurinol attenuates ischemia-induced hippocampal damage in the gerbil
Brain Research Bulletin, 1989Oxypurinol, an inhibitor of the enzyme xanthine oxidase, reduced ischemic hippocampal damage and the associated hypermotility in Mongolian gerbils. Cerebral ischemia was induced in unanesthetized gerbils by a bilateral 5-min occlusion of the carotid arteries.

Measurement of urinary oxypurinol by high performance liquid chromatography–tandem mass spectrometry
Journal of Chromatography B: Analytical Technologies in the Biomedical and Life Sciences, 2010 Oxypurinol is the active metabolite of allopurinol which is used to treat hyperuricaemia associated with gout. Both oxypurinol and allopurinol inhibit xanthine oxidase which forms uric acid from xanthine and hypoxanthine. Plasma oxypurinol concentrations

Clinical Pharmacokinetics and Pharmacodynamics of Allopurinol and Oxypurinol
Clinical Pharmacokinetics, 2007Allopurinol is the drug most widely used to lower the blood concentrations of urate and, therefore, to decrease the number of repeated attacks of gout. Allopurinol is rapidly and extensively metabolised to oxypurinol (oxipurinol), and the hypouricaemic efficacy of allopurinol is due very largely to this metabolite.

Oxypurinol Protects Normothermic Ischemic Hearts
Journal of Cardiac Surgery, 1990Rabbit hearts were mounted on a Langendorff apparatus and after measurement of baseline hemodynamic function exposed to 30 minutes normothermic arrest. Hearts were reperfused at 37 degrees C with buffer solution containing oxypurinol in different concentration: group II (0.01 mM), group III (0.1 mM), group IV (1 mM). Group I did not receive active drug

Allopurinol and oxypurinol in human breast milk
The Clinical Investigator, 1993To pregnant or breast feeding women drugs should be given with caution. We report the case of a 5-week-old breast-fed infant whose mother was taking 300mg allopurinol/day for 4 weeks. Allopurinol and oxypurinol were detected by HPLC in maternal plasma and breast milk with a method first described here.
