Most drug absorption occurs in the small intestine. Drugs disintegrate and dissolve in gastric juices in the stomach, but most are not absorbed here. Nothing is absorbed in the esophagus. Generally only water and a few nutrients are absorbed in the large intestine; some drugs can be absorbed from the rectum if they are administered as rectal suppositories.
