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

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), particularlyVonoprazan, 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.
