- To relieve chronic heartburn symptoms and other symptoms associated with GERD
- For the healing of erosive esophagitis
- For maintenance of healing of erosive esophagitis
- In combination with amoxicillin and clarithromycin for eradication of Helicobacter pylori infection in patients with duodenal ulcer disease.
- Zollinger-Ellison Syndrome
- Acid related Dyspepsia

Pharmacology
Esomeprazole is a proton pump inhibitor that inhibits the H+/K+-ATPase in the gastric parietal cell, suppressing gastric acid output. The first single optical isomer of a proton pump inhibitor, esomeprazole (S-isomer of omeprazole), provides superior acid control than racemic proton pump inhibitors.
Dosage & Administration
Healing of Erosive Esophagitis: 20 mg or 40 mg Once Daily for 4-8 Weeks. The majority of patients are healed within 4 to 8 weeks. For patients who don’t heal after 4-8 weeks, an additional 4-8 weeks of treatment may be considered. Maintenance of Healing of Erosive
Esophagitis: 20 mg Once Daily (Clinical studies did not extend 6 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.
Helicobacter Pylori eradication: Triple Therapy to reduce the risk of Duodenal Ulcer recurrence-Esomeprazole 40 mg Once Daily for 10 days, Amoxicillin 1000 mg Twice Daily for 10 days, Clarithromycin 500 mg Twice Daily for 10 days.
Zollinger-Ellison Syndrome: The dose is 20-80 mg once daily. The dosage should be adjusted individually and treatment continued as long as clinically indicated.
Acid-related Dyspepsia: 20-40 mg once daily for 2-4 weeks according to the response.
Duodenal ulcer: 20 mg once daily for 2-4 weeks. Gastric ulcer: 20-40 mg once daily for 4-8 weeks.
Interaction
CYP2C19 and CYP3A4 substantially metabolize esomeprazole in the liver. Esomeprazole does not appear to inhibit CYPs 1A2, 2A6, 2C9, 2D6, 2E1, or 3A4 in vitro or in vivo investigations. There should be no clinically significant interactions with medicines processed by these CYP enzymes. Esomeprazole has no clinically significant interactions with phenytoin, warfarin, quinidine, clarithromycin, or amoxicillin, according to drug interaction studies.
The principal Esomeprazole metabolizing enzyme, CYP2C19, may be harmed by Esomeprazole. The combination of Esomeprazole 30 mg and diazepam, a CYP2C19 substrate, resulted in a 45 percent reduction in diazepam clearance.
Contraindications
In patients who have a history of hypersensitivity to any of the formulations, esomeprazole is not recommended.
Side Effects
Headache, diarrhea, nausea, flatulence, abdominal pain, constipation, and dry mouth are the most common side effects reported with Esomeprazole. When compared to short-term treatment, there is no difference in the categories of linked adverse events noticed with maintenance treatment up to 12 months.
Pregnancy & Lactation
In pregnant women, there are no sufficient and well-controlled trials. No teratogenic effects have been found in animal investigations. Esomeprazole excretion in milk has not been studied. If the use of esomeprazole is thought necessary, breastfeeding should be terminated.
Precautions & Warnings
General: Symptomatic response to therapy with esomeprazole does not preclude the presence of gastric malignancy.
Information for patients: Esomeprazole capsules should be taken at least one hour before meals. For patients who have difficulty swallowing capsules, one tablespoon of applesauce can be added to an empty bowl and the Esomeprazole capsules can be opened, and the pellets inside the capsule carefully emptied onto the applesauce. The pellets should be mixed with the applesauce and then swallowed immediately.
