Rabeprazole
What is Rabeprazole for?
It strongly inhibits the secretion of gastric acid in the stomach by blocking the proton pumps in stomach cells. It acts as a first line drug for peptic ulcer. It can also be prescribed for prophylaxis of gastric ulcer when patients need to take drugs that cause gastrointestinal (GI) bleeding (such as aspirin).
