Description

Esomeprazole (Esonix) is a proton pump inhibitor that suppresses gastric acid secretion by specific inhibition of the H+/K+ATPase in the gastric parietal cell. By acting specifically on the proton pump, Esonix blocks the final step in acid production, thus reducing gastric acidity.

Indications

Gastroesophageal Reflux Disease (GERD)

Healing of Erosive Esophagitis

Maintenance of Healing of Erosive Esophagitis

Symptomatic Gastroesophageal Reflux Disease

H. pylori Eradication to Reduce the Risk of Duodenal Ulcer Recurrence

Pathological Hypersecretory Conditions Including

Zollinger-Ellison Syndrome

Side Effects

In general, Esomeprazole was well tolerated in both short- and long-term clinical trials. The most frequently occurring adverse events (>1%) are headache and diarrhea. nausea, flatulence, abdominal pain, constipation and dry mouth occurred at similar rates among patients taking Esomeprazole.

Precautions

Symptomatic response to therapy with Esomeprazole does not preclude the presence of gastric malignancy. Atrophic gastritis has been noted occasionally in gastric corpus biopsies from patients treated long-term with omeprazole, of which Esomeprazole is an enantiomer.

Use in Pregnancy & Lactation

In Pregnancy: Pregnancy Category C. This drug should be used during pregnancy only if clearly needed.
In Lactation: The excretion of Esomeprazole in milk has not been studied. As Esomeprazole is likely to be excreted in human milk, a decision should be
made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.
Lactation: Esomeprazole is excreted in human milk. Thus, a decision should be taken to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Drug Interaction

Drug interaction studies have shown that Esomeparzole does not have any clinically significant interactions with Phenytoin, Warfarin, Quinidine, Clarithromycin or Amoxicillin. Esomeprazole inhibits gastric acid secretion. Therefore, Esomeprazole may interfere with the absorption of drugs where gastric pH is an important determinant of bioavailability (eg, Ketoconazole, Iron salts and Dogoxin). Coadministration of oral contraceptives, Diazepam, Phenytoin or Quinidine did not seem to change the pharmacokinetic profile of Esomeprazole.

Over Dose

Drug interaction studies have shown that Esomeprazole does not have any clinically significant interactions with Phenytoin, Warfarin, Quinidine, Clarithromycin or Amoxicillin. Esomeprazole inhibits gastric acid secretion. Therefore, Esomeprazole may interfere with the absorption of drugs where
gastric pH is an important determinant of bioavailability (eg, Ketoconazole, Iron salts and Digoxin). Coadministration of oral contraceptives, Diazepam, Phenytoin or Quinidine did not seem to change the pharmacokinetic profile of Esomeprazole.

**If symptoms do not resolve completely after 4 weeks, an additional 4 weeks of treatment may be considered
