For example, cimetidine, ranitidine, famotidine, and roxatidine have been clinically used. However, if administration of the drug is stopped after healing, peptic ulcer recurs. In order to reduce such side effects (rebound phenomenon), a pyrimidone derivative having the following structure is known as a therapeutic agent for peptic ulcer having both a gastric acid secretion inhibitory action and a gastrointestinal mucosa protective action (JP-A-1-149774). No., Japanese Patent Application No. 1-125067).
