PROBLEM TO BE SOLVED: To provide a safe and efficient therapeutic agent for a gastric ulcer not having side effects that a proton pump inhibitor has, while having as much effect as or more effect than the proton pump inhibitor which is excellent as a therapeutic agent for a gastric ulcer.SOLUTION: The therapeutic agent for a gastric ulcer has a compound hydroxide structure having the crystal surface of hydrotalcites coated with an aluminum hydroxide-based substance hardly soluble to gastric acid, and displays strong adsorption power to a gastric mucosa and moderately high antacid capacity, and thus guards the stomach mucosa from the stomach acid over a long time.COPYRIGHT: (C)2011,JPO&INPIT【課題】胃潰瘍治療剤として優れているプロトンポンプ阻害剤と同等以上の効果をもちながら、プロトンポンプ阻害剤が有する副作用を持たない安全で高性能な胃潰瘍治療剤を提供する。【解決手段】ハイドロタルサイト類の結晶表面を胃酸に難溶性の水酸化アルミニウム系で被覆した複合水酸化物構造により、胃粘膜への強い吸着力と適度に高い制酸能力を発揮し、その結果、胃粘膜を長時間にわたり胃酸から防御する。【選択図】 なし
