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.
NCT00426595 ↗	Pharmacokinetics of Enteral Omeprazole Suspension in Patients With Cerebral Palsy and Mental Retardation	Completed	University Hospital, Ghent	Phase 2	2007-04-01	Gastroesophageal reflux disease and reflux-esophagitis are a major chronic problem in most children with cerebral palsy and mental retardation. Oral administration of enteric-coated formulations of the acid-labile proton pump inhibitor omeprazole is often problematic in these patients who may be suffering from swallowing disorders. A suspension of omeprazole in a sodium bicarbonate solution is often used for administration via the gastrostomy tube. This trial aims to compare the pharmacokinetics of omeprazole administered through the gastrostomy tube as a suspension in pediatric patients with cerebral palsy and mental retardation versus the pharmacokinetics of omeprazole administered as a multi-unit-pellet system (MUPS®). The crossover study will consist of 2 consecutive treatment periods of 14 days.
NCT00492622 ↗	Pharmacokinetics of Immediate-Release vs. Delayed-Release Omeprazole in Gastroparesis	Completed	Bausch Health Americas, Inc.	Phase 4	2007-06-01	The purpose of this study is to compare the blood drug levels of two prescribed medications, immediate-release omeprazole 40 mg powder and delayed-release omeprazole 40 mg capsule to determine which drug is better absorbed in patients with a slow stomach emptying (gastroparesis). Delayed-release omeprazole has a protective coating to prevent the drug omeprazole from being neutralized by stomach acid. Immediate-release omeprazole has sodium bicarbonate (antacid) which neutralizes the stomach acid, eliminating the need for a protective coating. Immediate-release omeprazole suspension may have a more rapid pharmacokinetic profile and greater overall drug absorption in gastroparesis.
