Gastritis, peptic ulcer, gastric cancer, etc. can cause stomach pain, and drugs can be used to inhibit gastric acid secretion and protect gastric mucosa. Gastric cancer patients can be given chemotherapeutic drugs. 1. Gastritis, peptic ulcer: Hâ‚‚ receptor antagonist (famotidine), proton pump inhibitor (omeprazole, pantoprazole) can inhibit gastric acid secretion. Bismuth (bismuth citrate), aluminum sulfate and other drugs can protect the gastric mucosa. People with H. pylori infection can use quadruple therapy for anti-H. pylori treatment, i.e. one bismuth agent + one proton pump inhibitor + two antibiotics (amoxicillin, furazolidone). 2. Gastric cancer: Gastric cancer is mainly treated by surgery, which can be combined with chemotherapy drugs (paclitaxel). The above drugs are recommended to be used under the guidance of doctors. There are many causes of stomach pain, so it is recommended to go to the hospital in time to find out the causes and treat them in time.
