Nausea needs to be treated symptomatically according to different etiologies. Commonly used drugs include central antiemetics, drugs that promote gastrointestinal motility, gastric acid inhibitors and gastric mucosal protectors: 1. Central antiemetics, commonly known as gastroflucan, are used for nausea and dry vomiting caused by radiotherapy or chemotherapy. 2. Drugs that promote gastrointestinal motility, such as morpholine, mosapride and domperidone, are used for nausea caused by indigestion. 3. Drugs that inhibit the secretion of gastric acid, mainly laparazoles, including omeprazole, rabeprazole and pantoprazole. Because stomach acid can irritate the gastric mucosa, it is often combined with drugs that protect the gastric mucosa.4. Drugs that protect the gastric mucosa, with colloidal properties, can form a protective layer on the surface of the gastric mucosa, such as aluminum phosphate gel.5. Drugs used for vomiting caused by motion sickness include vertigo stop, ride sickness, and for pregnancy vomiting are vitamin B6.
