Gastric pH and Anthocyanin Absorption
Anthocyanins are phytonutrients that provide blue, purple and red colors to fruits and vegetables. The purpose of the study is to determine whether absorption of anthocyanins occurs in the acid pH of the stomach and to determine whether altering stomach pH by use of an over-the-counter medicine, Prilosec TM, alters absorption of anthocyanins from strawberries and blackberries.

Omeprazole is a safe drug listed in OTC drug due to its safety. It acts by irreversible inhibition of K/H ATP ase pump and also Na/K ATP ase, Na/H ATP ase.Considering these actions the ef...
The purpose of this study is to evaluate the potential inhibitory effects of patupilone on metabolism using midazolam and omeprazole as the respective probe drugs.
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 deter...
The purpose of this clinical research study is to assess the effect of omeprazole at 20 mg on the pharmacokinetics of atazanavir administered as atazanavir with ritonavir relative to ataza...
The purpose of this study is to study gastritis, GI symptoms during long term omeprazole treatment
Previous studies have reported the efficacy of baclofen in the treatment of Gastroesophageal Reflux Diseases (GERD). The objective of present study is to evaluate the effect of co-administration of om...
The objectives were to document the pharmacokinetics of intravenous, enteric-coated oral and plain oral omeprazole in fasted horses and to investigate the impact of feeding on the bioavailability of a...
Objective It is believed that gastric pH interferes in levothyroxine absorption. Omeprazole, which acts by blocking the secretion of gastric acid, might interfere in hypothyroidism control in patients...
Anthocyanin is a critical factor involved in coloration of plant tissues, but the mechanism how medium pH values affect anthocyanin accumulation in woody plants is unknown. We analyzed anthocyanin com...
Proton pump inhibitors omeprazole and lansoprazole contain chiral sulfur atom and they are administered as a racemate, i.e. equimolar mixture of S- and R-enantiomers. The enantiopure drugs esomeprazol...
Medical and Biotech [MESH] Definitions
A cytochrome P-450 monooxygenase that can be induced by polycyclic aromatic xenobiotics in the liver of human and several animal species. This enzyme is of significant clinical interest due to the large number of drug interactions associated with its induction and its metabolism of THEOPHYLLINE. Caffeine is considered to be a model substrate for this enzyme. CYP1A2 activity can also be increased by environmental factors such as cigarette smoking, charbroiled meat, cruciferous vegetables, and a number of drugs including phenytoin, phenobarbital, and omeprazole.
Misunderstanding among individuals, frequently research subjects, of scientific methods such as randomization and placebo controls.
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
Hereditary disorders of pyruvate metabolism. They are difficult to diagnose and describe because pyruvate is a key intermediate in glycolysis, gluconeogenesis, and the tricarboxylic acid cycle. Some inherited metabolic disorders may alter pyruvate metabolism indirectly. Disorders in pyruvate metabolism appear to lead to deficiencies in neurotransmitter synthesis and, consequently, to nervous system disorders.
A highly effective inhibitor of gastric acid secretion used in the therapy of STOMACH ULCERS and ZOLLINGER-ELLISON SYNDROME. The drug inhibits the H(+)-K(+)-ATPase (H(+)-K(+)-EXCHANGING ATPASE) in the proton pump of GASTRIC PARIETAL CELLS.
