Vomiting is a complex reflex activity. Various antiemetics can exert antiemetic effects by affecting different parts of vomiting and reflex, such as inhibiting chemoreceptors, cerebral cortex, vestibular auricles or directly acting on the vomiting center. Therefore, medication should be used. Choose according to the ground. In general, antiemetics are superior to treatment in preventing vomiting, especially vomiting caused by motion sickness, radiation sickness or chemotherapy. Pregnancy should be carefully selected for vomiting in pregnancy. Diphenhydramine, diphenhydramine, etc. are generally used only. Phenothiazines are only used when vomiting is severe. Common antiemetic drugs include: 1 phenothiazines such as chlorpromazine and thioethylazine (Tailai Kang). 2 antihistamines such as diphenhydramine, diphenhydramine and the like. 3 other such as scopolamine, metoclopramide (gastric ampoules) (see "29, digestive drugs, swelling and gastrointestinal motility function regulating drugs"), and 5-HT3 receptor blockers. The emetic is mainly used to induce acute poisoning to vomit the stomach poison. Its emetic function is mainly through excitatory central emetic chemoreceptors, such as apomorphine or stimulating the digestive tract reflex excitatory vomiting center. At present, gastric lavage is often used instead of emetic medicine.
