Proton Pump Inhibitor


Esomeprazole is a proton pump inhibitor that suppresses gastric acid secretion by specific inhibition of the H+/K+ ATPase in the gastric parietal cell. Esomeprazole (S-isomer of omeprazole) is the first single optical isomer of proton pump inhibitor, provides better acid control than racemic proton pump inhibitors.

  • Maintenance of healing of erosive esophagitis: 20 mg once daily. Controlled studies did not extend beyond six months.
  • Symptomatic GERD: 20 mg once daily for 4 weeks. If symptoms do not resolve completely after 4 weeks, an additional 4 weeks of treatment may be considered.
  • H.pylori eradication (Triple therapy): Esomeprazole 20 mg twice daily for 10 days, Amoxicillin 1000 mg Twice daily for 10 days and Clarithromycin 500 mg twice daily for 10 days

Esomeprazole appears to be a selective inhibitor of the cytochrome P450 mono-oxygenase system, there may be an effect on hepatic clearance, but there have been no reports to date of clinically relevant interactions. There is some uncertainty over the effect of Esomeprazole on the oral combined contraceptive pill. Physiological changes similar to those found with omeprazole are likely to take place because of the reduction in gastric acid which is likely to influence the bacterial colonization of the stomach and duodenum and also vitamin B12 absorption.


Esomeprazole is contraindicated in those patients who have known hypersensitivity to any other components of the formulation.
