Nov. 01, 2023, FDA has approved VOQUEZNA (vonoprazan) tablets, a novel potassium-competitive acid blocker (PCAB), as a new treatment for adults for the healing of all grades of Erosive Esophagitis, also known as Erosive GERD (gastroesophageal reflux disease).
PCABs are a novel class of medicines that block acid secretion in the stomach, and VOQUEZNA is the first PCAB to be approved in the U.S. Vonoprazan has shown the potential to provide acid suppression that can achieve pH levels that are important in enhancing treatment effectiveness.
