Rabeprazole Tablet, Oral Delayed Release Capsule, Oral Delayed Release Tablet

Rabeprazole Sodium is an antiulcerant drug in the class of Proton Pump Inhibitors. Rabeprazole Sodium is a substituted benzimidazole which suppresses gastric acid secretion by inhibiting the gastric H+/K+-ATPase enzyme at the secretory surface of the gastric parietal cell. It is an enteric coated tablet, because of its coated formulation it is highly stable in stomach and because of higher pKa value of Rabeprazole Sodium it provides faster onset of action. It blocks the final step of gastric acid secretion.

After oral administration of 20 mg, Rabeprazole is absorbed and can be detected in plasma by 1 hour. The effects of food on the absorption of Rabeprazole have not been evaluated. Rabeprazole is 96.3% bound to human plasma proteins. Rabeprazole is primarily metabolized in the liver by Cytochrome P-450 3A (Sulphone metabolite) and 2C19 (Desmethyl Rabeprazole). Following a single 20 mg oral dose of Rabeprazole, approximately 90% of the drug is eliminated in the urine.The remainder of the dose is excreted in the feaces.

Treatment of Symptomatic Gastroesophageal Reflux Disease (GERD):The recommended adult oral dose is 20 mg once daily for 4 weeks. If symptoms do not resolve completely after 4 weeks, an additional course of treatment may be considered.

Healing of Duodenal Ulcers:The recommended adult oral dose is 20 mg once daily after the morning meal for a period up to four weeks. Most patients with duodenal ulcer heal within four weeks. A few patients may require additional therapy to achieve healing.

Helicobacter pylori Eradication: To Reduce the Risk of Duodenal Ulcer Recurrence-

  • Rabeprazole Sodium 20 mg Twice Daily for 7 Days
  • Amoxicillin 1000 mg Twice Daily for 7 Days
  • Clarithromycin 500 mg Twice Daily for 7 Days

All three medications should be taken twice daily with the morning and evening meals. It is important that patients comply with the full 7-day regimen.

Treatment of Pathological Hypersecretory Conditions Including Zollinger-Ellison Syndrome: The dosage of Rabeprazole Sodium in patients with pathologic hypersecretory conditions varies with the individual patient. The recommended adult oral starting dose is 60 mg once a day. Doses should be adjusted to individual patient needs and should continue for as long as clinically indicated. Some patients may require divided doses. Doses up to 100 mg QD and 60 mg BID have been administered.

Administration of Rabeprazole Sodium to patients with mild to moderate liver impairment resulted in increased exposure and decreased elimination. Caution should be exercised in patients with severe hepatic impairment.


Rabeprazole is metabolized by the Cytochrome P-450 (CYP-450) drug metabolizing enzyme system. Rabeprazole does not have clinically significant interactions with other drugs metabolized by the CYP-450 system,such as Warfarin and Theophylline given as single oral dose, Diazepam as a single intravenous dose, and Phenytoin given as a single intravenous dose. In normal subjects, co-administration of Rabeprazole 20 mg QD resulted in an approximately 30% decrease in the bioavailability of Ketoconazole and increase in the AUC and Cmax for digoxin of 90% and 29% respectively.
