Rasonix 20 tablet: Each enteric-coated tablet contains Rabeprazole Sodium INN 20 mg.
Rasonix 10 capsule: Each sprinkle capsule contains Rabeprazole Sodium INN 10 mg.
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.

In general, Rabeprazole is well-tolerated in both short-term and long-term studies. Rabeprazole may some times cause headache, diarrhoea, abdominal pain, vomiting, constipation, dry mouth, increased or decreased appetite, muscle pain, drowsiness, dizziness.
Rabeprazole Sodium tablets should not be splited, chewed or crushed.
Pregnant women: Rabeprazole is FDA pregnancy category B. No data are available on administration of Rabeprazole to pregnant women. However this drug should be used during pregnancy, only if clearly needed.
Lactating mother: There are no data on the excretion of Rabeprazole into the breast milk. A decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the benefit of the drug to the mother.
The safety and effectiveness of Rabeprazole in pediatric patients have not been established.
Rabeprazole is metabolized by the cytochrome P-450 (CYP-450) enzyme system. Studies in healthy subjects have shown that 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 doses, diazepam as a single intravenous dose, and phenytoin given as a single intravenous dose.
There is no experience with large overdosages with Rabeprazole. The maximum reported overdose 80 mg. There were no clinical signs or symptoms associated with any reported overdose. Patients with Zollinger-Ellison syndrome have been treated with up to 120 mg Rabeprazole once daily. No specific antidote for Rabeprazole is known.
