Abeprazan hydrochloride (DWP14012 hydrochloride) is a potassium-competitive acid blocker. Abeprazan hydrochloride inhibits H + , K + - ATPase by reversible potassium-competitive ionic binding with no acid activation required. Abeprazan hydrochloride is developed as a potential alternative to proton pump inhibitor for the treatment of acid-related diseases.
In Vitro
The mechanism of action of Abeprazan hydrochloride is reversibly binding to H + , K + ‐ATPase, and, unlike that of PPIs, does not require acidic environment for drug activation. MCE has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
Abeprazan hydrochloride (DWP14012 hydrochloride) inhibits acid secretion in a dose-dependent manner and the inhibition of gastric acid secretion is equal to or greater than that of vonoprazan, a previously approved P-CAB, in various in vivo studies using pylorus-ligated rats, lumen-perfused rat models and heidenhain pouch dog models . MCE has not independently confirmed the accuracy of these methods. They are for reference only.
