It is better to take rabeprazole, cimetidine and thioglycollate for bad stomach and excessive acidity. People with bad stomach and excessive stomach acid need to be treated with drugs that inhibit the secretion of stomach acid. When the secretion of stomach acid is controlled, it can reduce the infringement on the stomach wall and facilitate the recovery of stomach diseases. Rabeprazole is a proton pump inhibitor, which can inhibit the activity of the proton pump of the stomach wall after taking the drug, thus blocking the step of gastric acid secretion, the effect of acid inhibition is more lasting and causes less side effects to the human body. Cimetidine is a H2 receptor antagonist, not only can the main gastric acid secretion, but also can neutralize the gastric acid in the stomach, reduce the concentration of gastric acid, for excessive gastric acid has a rapid relief effect. After taking thioglycollate, it can isolate gastric acid from pepsin, increase the blood flow of gastric mucosa, and promote the repair of mucosa, when the protective barrier of gastric mucosa is repaired, it can better defend against gastric acid.
