Evaluating Vonoprazan for the treatment of erosive GERD and heartburn associated with GERD in adults.

Abstract

Introduction: Gastroesophageal reflux disease (GERD) is a common debilitating chronic disease presenting in two main forms based on esophageal mucosal appearance, the erosive reflux disease (ERD) and the non-erosive reflux disease (NERD). Acid secretion is a key factor in the disease pathogenesis and management. Potent acid-suppressant drugs have been manufactured since the mid of 1970s, initially with histamine-H2-receptors antagonists, and later, inhibitors of the proton pump (H+-K+-ATPase). More recently, potassium-competitive acid blockers (P-CABs), particularly Vonoprazan, have been introduced. Vonoprazan has shown high efficacy and safety profiles and exhibits several advantages that allow to overcome shortcomings of proton pump inhibitors (PPIs).

Areas covered: In this review, we provide an updated summary of Vonoprazan pharmacodynamics and its role in clinical practice for the management of erosive esophagitis and GERD related heartburn. Moreover, we discuss characteristics of Vonoprazan that allow to bypass some limitations of the older PPIs.

Expert opinion: Long-term safety and efficacy of Vonoprazan have already been demonstrated for the induction and maintenance of ERD, preventing nocturnal acid breakthrough, reducing reflux symptoms in non-responder to standard therapy. Ongoing and future studies are expected to further elucidate its long-term benefits and potential applications in other acid-related disorders.
