WebThe intraluminal pH is rapidly changed from highly acid in the stomach to about pH 6 in the duodenum. The pH gradually increases in the small intestine from pH 6 to about pH 7.4 in the terminal ileum. The pH drops to 5.7 in the caecum, but again gradually increases, reaching pH 6.7 in the rectum. WebThe distribution constant is pH dependent and the term logD is used to reflect the pH dependent lipophilicity of a drug. The lower the pH of an aqueous solution, the further to the left is the position of equilibrium, i.e. increasing [drug molecule] water and decreasing [drug ion] water. Below a certain pH, [drug ion] water becomes close to zero.
