none
CI for PPI
none
CI for prokinetics
met -> cross BBB (tremors, parkinsons, seizures)

electrolytic disorder
MOA of Alginates
form a viscous “raft” that floats in stomach
MOA of antacids
neutral acid
inhibit pepsin generation binds to bile acid
MOA of H2RAs
parietal cells pump H+
inhibit H2R to prevent H+
decrease basal/stimulated acid secretion
MOA of PPI
direct inhibit proton pump prodrug activated by duodenum
MOA of prokinetics
dopamine antagonist stimulate gastric motility
Administration of alginates
~1 hr after meal
Administration of Antacids
up to QID
Administration of H2RAs
give 30-60 min before meal
