Prostaglandins provide a protective barrier that prevent the stomach from digesting itself. If there is a break in the protective barrier, mucosal injury occurs. Injury worsen by histamine release and vagal nerve stimulation. Hydrochloric acid diffuse back into the mucosa and injure small vessels. This causes edema, hemorrhage, and erosion of the stomach's lining.
Thus in acidic medium acidic drug is present more in unionized form, which increases its absorption. This is why acidic drugs are better absorbed from the stomach. Basic drugs get ionized in acidic medium (right shift of eq 2), thus this form is poorly absorbed. Aspirin, an acidic drug is unionized in acidic medium of stomach, so is easily absorbed.
