Rabeprazole sodium is an antiulcer 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.

Approximately 90% of the drugs is eliminated in the urine. The remainder of the dose is recovered in the faeces.
