Omeprazole exerts practically no other action except
inhibition of gastric acid secretion because:
A. It transforms into the active cationic forms
only in the acidic pH of the gastric juice
B. Its active forms have selective affinity for the
H+K+ATPase located in the apical canaliculi
of gastric parietal cells
C. Its cationic forms are unable to diffuse out
from the gastric parietal cell canaliculi
D. All of the above
