Vonoprazan (Vonoprazan fumarate or TAK-438) under brand name Takecab, discovered by Takeda, is a new medicine for treating acid-related diseases with a novel mechanism of action called potassium-competitive acid blockers (P-CABs) which competitively inhibits the binding of potassium ions to H+,K+-ATPase (also known as the proton pump) in the final step of gastric acid secretion in gastric parietal cells. The drug is approved in Japan for the treatment of acid-related diseases, including gastric ulcer, duodenal ulcer, reflux esophagitis and Adjunct to Helicobacter pylori eradication in the case of Helicobacter pylori gastritis.
