Since a long time back allopurinol has been constantly use to subsidize uric acid level in blood by competitive and suicidal inhibition of xanthine oxidase. Barring a few side few tolerable effects there was never felt any emergency for invention of an alternative. But a dire research was going on to bring into light an alternative which is better than allopurinol in some aspects. Now a non-pur...

over production of uric acid by xanthine oxidase (xo) causes gout. xo inhibitors for example allopurinol are the most important available anti gout drugs. medicinal herbs are available natural sources that may be useful for the treatment of gout. in this study the inhibitory activity of aqueous extracts of matricaria chamomilla l., hypericum perforatum l., fraxinus excelsior l., zea mays l., tr...

Fifty-nine patients with primary gout were treated with either a combination of colchicine and allopurinol or colchicine alone. Assessments of renal function over 2 years revealed a statistically significant fall of glomerular filtration rate an urine concentrating ability in those receiving only colchicine. The renal function of patients given allopurinol did not change. Treatment with allopur...

Robust epidemiological data link higher levels of the antioxidant urate to a reduced risk of developing Parkinson's disease (PD) and to a slower rate of its progression. Allopurinol, an inhibitor of xanthine oxidoreductase (XOR), blocks the oxidation of xanthine to urate. The present study sought to determine whether lowering levels of urate using allopurinol results in exacerbated neurotoxicit...

Background: Ischemia and reperfusion after transplantation is the main problem which decreases follicular density in the grafted ovarian. Many sources of free radicals such as xanthine oxidase were generated during ischemia. In this study, we used allopurinol as xanthine oxidase inhibitor to reduce ischemia-reperfusion injury, to increase received oocytes and embryos, and to decrease Apoptosis ...

Gout recently passed rheumatoid arthritis to become the most common inflammatory arthritis in the United States (US). However, epidemiologic studies indicate that the quality of gout management is suboptimal owing to both patient and physician issues. Only three options for urate-lowering therapy are currently available in the US: allopurinol, probenecid, and recently, febuxostat. Probenecid is...

OBJECTIVE The central strategy for effective gout management is longterm urate-lowering therapy to maintain the serum urate at a level below 0.36 mmol/l. We sought to determine the prevalence of gout and the quality of care in a national Australian general practice population. METHODS Data were from general practice point-of-care electronic records over a 5-year period (n = 1,479,449). Inform...

BACKGROUND Dilated cardiomyopathy is characterized by an imbalance between left ventricular performance and myocardial energy consumption. Experimental models suggest that oxidative stress resulting from increased xanthine oxidase (XO) activity contributes to this imbalance. Accordingly, we hypothesized that XO inhibition with intracoronary allopurinol improves left ventricular efficiency in pa...

Febuxostat is a xanthine oxidase inhibitor that during the last years has successfully replaced allopurinol treatment in patients with chronic kidney disease (CKD) and hyperuricemia. Several adverse events have been observed during therapy with febuxostat. DRESS (Drug Reaction with Eosinophilia and Systemic Symptoms) syndrome induced by febuxostat has been poorly described, mainly in patient wi...

Gout is associated with a high risk of cardiovascular diseases and mortality. Possible causes the disease include persistent uncontrolled hyperuricemia, chronic microcrystalline inflammation that develops in vascular wall even atherosclerotic plaques. These processes, which contribute to oxidative stress formation peroxidation products, may be target for xanthine oxidase inhibitors — allopurino...
