Description:
The active ingredient in Rasonix is Rabeprazole sodium, a rapid acting proton pump inhibitor (PPI). Rabeprazole is a substituted benzimidazole which suppresses gastric acid secretion by inhibiting the gastric H+/ K+ ATPase at the secretory surface of the gastric parietal cell. This enzyme is regarded as the acid (proton) pump within the parietal cell. Rabeprazole blocks the final step of gastric acid secretion. The stability of Rabeprazole sodium depends on pH; it is rapidly degraded in acid media, and is more stable under alkaline conditions. Because of its enteric coated formulation Rasonix is highly stable in stomach and higher pKa value of Rabeprazole provides faster action compared to other PPIs.
Indications
i) Duodenal ulcer
ii) Benign gastric ulcer
iii) Duodenal ulcer and benign gastric ulcer associated with H. pylori infection
iv) Healing of erosive or ulcerative Gastroesophageal Reflux Disease (GERD
v) Treatment of symptomatic GERD
vi) Maintenance of healing of erosive or ulcerative GERD
vii) Prevention or treatment of NSAID-induced ulcers
viii) Zollinger-Ellison Syndrome.
Dosage & Administration
Healing of Erosive or Ulcerative Gastroesophageal Reflux Disease (GERD): 20 mg to be taken once daily for 4 to 8 weeks. For those patients who have not healed after 8 weeks of treatment, an additional 8 week course may be considered.
Maintenance of Healing of Erosive or Ulcerative Gastroesophageal Reflux Disease (GERD Maintenance): The recommended adult oral dose is 20 mg once daily.
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:Â 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. Some patients with Zollinger-Ellision syndrome have been treated continuously with Rabeprazole Sodium for up to one year.
