The site that leads to the duodenum is called pyloric. The pylorus regulates the rate at which the stomach contents descend to the duodenum. When you eat a lot of food is stored in the stomach and discharged into the duodenum at a constant rate. If you eat a large amount at a time, the speed of going down is constant, so after a certain limit, you can no longer eat, and if you are severely vomiting. But after the pylorus, there are no anatomical structures in the small intestine and the large intestine that prevent the contents from going down. Therefore, if the drug is injected directly into the duodenum rather than the stomach, the drug easily descends into the small and large intestines without causing nausea or vomiting.
