NCT00045799 ↗	Safety & Efficacy of Omeprazole Sodium Bicarbonate for the Prevention of Upper GI Bleeding in the Critically Ill	Completed	Bausch Health Americas, Inc.	Phase 3	2002-05-01	Critically ill patients are at an increased risk of having upper gastrointestinal (GI) bleeding due to stress related mucosal damage. Cimetidine, delivered continuously through intravenous infusion, is the only drug that the FDA has approved for the prevention of upper GI bleeding in critically ill patients. The present trial is intended to assess the safety and efficacy of an omeprazole sodium bicarbonate immediate-release suspension in this indication.
NCT00045799 ↗	Safety & Efficacy of Omeprazole Sodium Bicarbonate for the Prevention of Upper GI Bleeding in the Critically Ill	Completed	Valeant Pharmaceuticals International, Inc.	Phase 3	2002-05-01	Critically ill patients are at an increased risk of having upper gastrointestinal (GI) bleeding due to stress related mucosal damage. Cimetidine, delivered continuously through intravenous infusion, is the only drug that the FDA has approved for the prevention of upper GI bleeding in critically ill patients. The present trial is intended to assess the safety and efficacy of an omeprazole sodium bicarbonate immediate-release suspension in this indication.
NCT00130598 ↗	PROVOCATION Trial - PROphylactic intraVenOus Hydration for Contrast Agent Toxicity PreventION	Completed	Swiss National Science Foundation	Phase 2/Phase 3	2005-06-01	Contrast nephropathy (CN) remains a common complication of radiographic procedures and an important cause of hospital-acquired acute renal failure. Only hydration with saline is uniformly accepted and used in clinical practice as a cornerstone for the prevention of CN. But the optimal preventive strategy for CN is not known. Sodium bicarbonate might be even more effective than hydration with sodium chloride for prophylaxis of CN. Therefore the aim of the study is to evaluate the efficacy of two regimens of sodium bicarbonate compared with a prolonged infusion of sodium chloride in the prevention of CN. Primary endpoint: Decrease in glomerular filtration rate (GFR) within 48 hours.

NCT00142272 ↗	Single Dose Ciprofloxacin in the Treatment of Childhood Cholera:Randomized Controlled Clinical Trial	Completed	Bayer	Phase 3	2001-05-01	The study will be conducted to compare the efficacy and safety of a single dose of ciprofloxacin oral suspension 20 mg/kg with a 3-day course of erythromycin oral suspension administered in a dose of 12.5 mg/kg every 6 hours (12 doses) in the treatment of children, aged 2-15 years with clinically severe cholera due to V. cholerae O1 or O139. We hypothesize that single dose ciprofloxacin would result in similar outcome in the clinicalcurewith that of erythromycin given in multiple doses.
