All Clinical Trials for Allopurinol Sodium

Trial ID Title Status Sponsor Phase Start Date Summary
NCT00189007 ↗ Antenatal Allopurinol During Fetal Hypoxia Unknown status ZonMw: The Netherlands Organisation for Health Research and Development Phase 3 2009-10-01 A former study (submitted) in 32 severely asphyxiated infants participating in a randomized double blind study, in which early postnatal allopurinol or a placebo (within 4 hours after birth) was administered to reduce free radical formation and consequently reperfusion/reoxygenation injury to the newborn brain, showed an unaltered high mortality and no clinically relevant improvement in morbidity in infants treated with allopurinol. It was hypothesized that postnatal allopurinol treatment started too late to reduce reperfusion-induced free radical surge and that initiating allopurinol treatment of the fetus with (imminent) hypoxia already via the mother during labor will be more effective to reduce free radical-induced post-asphyxial brain damage.
NCT00189007 ↗ Antenatal Allopurinol During Fetal Hypoxia Unknown status UMC Utrecht Phase 3 2009-10-01 A former study (submitted) in 32 severely asphyxiated infants participating in a randomized double blind study, in which early postnatal allopurinol or a placebo (within 4 hours after birth) was administered to reduce free radical formation and consequently reperfusion/reoxygenation injury to the newborn brain, showed an unaltered high mortality and no clinically relevant improvement in morbidity in infants treated with allopurinol. It was hypothesized that postnatal allopurinol treatment started too late to reduce reperfusion-induced free radical surge and that initiating allopurinol treatment of the fetus with (imminent) hypoxia already via the mother during labor will be more effective to reduce free radical-induced post-asphyxial brain damage.
NCT00241839 ↗ Uric Acid and Hypertension in African Americans Completed University of Florida Phase 3 2005-08-01 This study will test the hypothesis that the administration of a xanthine oxidase inhibitor (allopurinol) will prevent thiazide-induced hyperuricemia, which will result in better blood pressure (BP) control in African Americans.
NCT00317629 ↗ Controlled Nitric Oxide Releasing Patch Versus Meglumine Antimoniate in the Treatment of Cutaneous Leishmaniasis Terminated Secretaria de Salud de Santander Phase 3 2006-05-01 Cutaneous leishmaniasis is a worldwide disease, endemic in 88 countries, that has shown an increasing incidence over the last two decades. So far, pentavalent antimony compounds have been considered the treatment of choice, with a percentage of cure of about 85%. However, the high efficacy of these drugs is counteracted by their many disadvantages and adverse events. Previous studies have shown nitric oxide to be a potential alternative treatment when administered topically with no serious adverse events. However, due to the unstable nitric oxide release, the topical donors needed to be applied frequently, making the adherence to the treatment difficult. The electrospinning technique has allowed the production of a multilayer transdermal patch that produces a continuous and stable nitric oxide release. The main objective of this study is to evaluate this novel nitric oxide topical donor for the treatment of cutaneous leishmaniasis. A double-blind, randomized, double-masked, placebo-controlled clinical trial, including 620 patients from endemic areas for leishmaniasis in Colombia was designed to investigate whether this patch is as effective as meglumine antimoniate for the treatment of cutaneous leishmaniasis but with less adverse events. Subjects with ulcers characteristic of cutaneous leishmaniasis will be medically evaluated and laboratory tests and parasitological confirmation performed. After checking the inclusion/exclusion criteria, the patients will be randomly assigned to one of two groups. During 20 days Group 1 will receive simultaneously meglumine antimoniate and placebo of nitric oxide patches while Group 2 will receive placebo of meglumine antimoniate and active nitric oxide patches. During the treatment visits, the medications will be administered daily and the presence of adverse events assessed. During the follow-up, the research group will visit the patients at days 21, 45, 90 and 180. The healing process of the ulcer, the health of the participants, recidivisms and/or reinfection will also be assessed. The evolution of the ulcers will be photographically registered. In the case that the effectiveness of the patches is demonstrated, a novel and safe therapeutic alternative for one of the most important public health problems in many countries will be available to patients.
NCT00317629 ↗ Controlled Nitric Oxide Releasing Patch Versus Meglumine Antimoniate in the Treatment of Cutaneous Leishmaniasis Terminated Secretaria de Salud de Tolima Phase 3 2006-05-01 Cutaneous leishmaniasis is a worldwide disease, endemic in 88 countries, that has shown an increasing incidence over the last two decades.
