Drugs such as omeprazole and ranitidine can reduce stomach acid, and so can a diet of raw peanuts and soda crackers. Excessive secretion of stomach acid will cause corrosion of the gastric mucosa, so it is more likely to induce gastritis, gastric ulcer and other diseases. The main treatment for excessive secretion of stomach acid is drugs that inhibit the secretion of stomach acid. Omeprazole is a common drug that inhibits stomach acid and is a proton pump inhibitor, which can inhibit the activity of the proton pump and thus block the steps of stomach acid secretion, which not only has a strong effect of inhibiting stomach acid, but also has a longer onset of action. Ranitidine is an H2 receptor blocker, which not only inhibits gastric acid and pepsin activity, but also promotes blood circulation in the gastric mucosa and facilitates the repair of the gastric mucosa. Raw peanuts are an alkaline food. Chewing raw peanuts can effectively neutralize stomach acid and reduce the secretion of stomach acid when stomach acid secretion is high. Soda crackers can not only replenish the body’s energy, and the cookies contain sodium bicarbonate, which can balance the body’s pH, so for the excessive secretion of stomach acid also has a regulatory effect.
