Rabeprazole in the treatment of acid-related disorders

Proton-pump inhibitors (PPIs) are widely used to treat acid-related disorders (ARD). Rabeprazole is a potent inhibitor of gastric H+/K+-ATPase, and it is indicated for the treatment of gastroesophageal reflux disease, Zollinger-Ellison syndrome, gastric and duodenal ulcers and for Helicobacter pylori eradication (in combination with antibiotics), as well as for the treatment of ARD described in this article. Pharmacokinetic and pharmacodynamic data show that rabeprazole provides a marked acid inhibition from the first administration, which persists with repeated use. Due to the predominantly non-enzymatic metabolism, rabeprazole has a lower interaction potential between drugs. Besides, rabeprazole maintains a high intragastric pH and achieves maximum acid inhibition in 24 hours. Rabeprazole is characterized by linearity of pharmacokinetics, which remains unchanged in renal and hepatic insufficiency. Rabeprazole is available in the dosage form of enteric capsules due to the PPIs instability in an acidic environment. Rabeprazole is generally well-tolerated by patients. Besides several minor side effects, rabeprazole is safe to be widely used in the treatment of ARD.
