Heartburn and heartburn are mostly caused by excessive secretion of gastric acid, and should be taken orally under the guidance of a physician, such as acid-suppressing drugs and gastric mucosal protectants. 1. Acid suppressants (1) proton pump inhibitors: these drugs are commonly found in omeprazole, pantoprazole, etc. By inhibiting the secretion of acidic liquid at the gastric mucosa, it slows down the corrosion and destruction of the situation, thus relieving the feeling of stomach discomfort. (2) H2 receptor antagonist: clinically commonly used ranitidine, famotidine and other drugs, by antagonizing the H2 receptor, reduce gastric acid secretion, thus reducing the symptoms of heartburn, heartburn. 2. Gastric mucosal protectants: for example, bismuth pectin, aluminum sulfate and other drugs, drugs taken orally, can form a layer of protective film on the surface of the gastric mucosa, part of the mucosal protectants can also neutralize the gastric acid, to avoid the destruction of gastric acid. It is recommended to go to the hospital and actively cooperate with professional doctors for diagnosis and treatment when you feel uncomfortable symptoms such as burning sensation and heartburn in the stomach.
