Specialized drugs for gastric diseases include drugs that inhibit gastric acid secretion, such as proton pump inhibitors such as omeprazole, H2 receptor antagonists such as famotidine; gastric mucosal protectants such as bismuth; gastrointestinal stimulants such as domperidone and so on. 1. Drugs to inhibit gastric acid secretion: proton pump inhibitors such as omeprazole, lansoprazole, pantoprazole, rabeprazole, epprazole, can inhibit the activity of H⁺-K⁺-ATPase, thus inhibiting the secretion of gastric acid; H2 receptor antagonists such as famotidine, nizatidine, ranitidine. 2. Drugs to protect gastric mucosa: such as bismuth; weakly alkaline antacids, including magnesium aluminum carbonate, aluminum phosphate, aluminum thiosulfate, aluminum hydroxide gel. 3.
