WebThus, in plasma (pH 7.4), the ratio of un-ionized to ionized forms for a weak acid (eg, with a p K a of 4.4) is 1:1000; in gastric fluid (pH 1.4), the ratio is reversed (1000:1). Therefore, when a weak acid is given orally, most of the drug in the stomach is un-ionized, favoring diffusion through the gastric mucosa. WebIn general, the human physiological pH for most tissues is around 7 ~ 7.4 with some exceptions ( Figure 2 ). For instance, the stomach pH is 1 ~ 3, small intestine pH is 4 ~ 7, and blood pH is 7.3 ~ 7.45. Therefore, the same drug may exist in different ionic states in different regions of the body. images of old plantation dresses
