Esomeprazole (E6009-GRP)

Esomeprazole ((S)-Omeprazole, (-)-Omeprazole) is a potent inhibitor of proton pump. It decreases acid production by inhibiting the H+, K+-ATPase enzyme in gastric parietal cells. Esomeprazole displays pharmacokinetic properties that make it more effective than omeprazole and has the potential for use in research of symptomatic gastroesophageal reflux disease.
