Abstract

Acid-related disease is a common, public health problem that interferes with the livelihoods of patients. The most effective and re–commended drugs to inhibit acid secretion in the current guideline are proton pump inhibitors. It is later found to be less effective as well as to have other limitations such as gastric acid-lability, inhibition of H+/K+-ATPase enzyme only in stimulated state, and variable effects in patients with genetic differences. They are also unable to control symptoms during the night. In addition, long-term side effects such as reduction of the absorption of vitamin B12 and magnesium are observed. Therefore, efforts have been made to develop anti-acid secretion drugs to reduce these limitations. The most recent class of acid secretion inhibitors is the potassium competitive acid blocker, vonoprazan. The drug has advantages of rapid and long-acting. It is gastric acid-resistant. Food does not interfere with drug absorption, and drug can control nighttime symptoms. It is thus a new alternative for the treatment of acid-related diseases. However, long term study awaits investigation.
