What medications can improve gastrointestinal function?

　　Common medications for improving gastrointestinal function generally include Domperidone tablets, Omeprazole enteric-coated capsules, Bifidobacterium quadruple viable tablets, Hydrotalcite chewable tablets, and Lactulose oral solution. Detailed explanations are as follows:

　　1. Domperidone Tablets: As a gastrointestinal prokinetic agent, Domperidone tablets selectively act on peripheral dopamine receptors, enhancing the motility of the gastric antrum and duodenum, promoting gastric emptying, and coordinating pyloric contractions. They effectively alleviate symptoms such as nausea, vomiting, abdominal distension, and early satiety and are commonly used to treat gastrointestinal motility disorders caused by functional dyspepsia and gastroesophageal reflux disease (GERD).

　　2. Omeprazole Enteric-Coated Capsules: As a proton pump inhibitor, Omeprazole enteric-coated capsules specifically act on the secretory membrane after entering gastric parietal cells, inhibiting the activity of proton pumps, thereby blocking the final step of gastric acid secretion. This significantly reduces gastric acid secretion volume and lowers gastric acid concentration. They are commonly used to treat acid-related diseases such as gastric ulcers, duodenal ulcers, and reflux esophagitis.

　　3. Bifidobacterium Quadruple Viable Tablets: This compound probiotic preparation contains Bifidobacterium, Lactobacillus acidophilus, Enterococcus faecalis, and Bacillus cereus. It directly replenishes normal physiological bacteria in the human body, forming a biological barrier in the intestines that inhibits certain pathogenic bacteria, maintains normal intestinal motility, regulates intestinal flora imbalance, and improves symptoms such as diarrhea, constipation, and indigestion.

　　4. Hydrotalcite Chewable Tablets: This over-the-counter medication belongs to the class of antacids and gastric mucosal protectants. Its main component, hydrotalcite, rapidly neutralizes gastric acid and maintains this effect for a prolonged period. It can reversibly and selectively bind bile acids, continuously preventing gastric damage caused by pepsin. It also enhances protective factors in the gastric mucosa and aids in repairing damaged mucosa. It is commonly used to relieve symptoms such as stomach pain and heartburn caused by excessive gastric acid secretion.

　　5. Lactulose Oral Solution: As a semisynthetic disaccharide, Lactulose oral solution is not absorbed in the gastrointestinal tract but is broken down by colonic bacteria into low-molecular-weight organic acids, increasing intestinal acidity, stimulating colonic peristalsis, maintaining bowel regularity, alleviating constipation, restoring physiological colonic rhythm, and also used for the treatment and prevention of hepatic encephalopathy.

　　In daily life, it is important to develop regular eating habits, eat meals at fixed times and in appropriate quantities, and avoid overeating and consuming irritating foods. Maintaining moderate physical activity promotes gastrointestinal motility. If gastrointestinal function is impaired, the above medications should be used rationally under the guidance of a physician, and self-medication should be strictly avoided.
