2. PPIs -
Omeprazole, Lansoprazole, Pantoprazole - 4What is the class and MOA for: Lansoprazole Omeprazole PantoprazoleCLASS: PPI
MOA: Bind irreversibly to H/K ATPase and inhibit the protein pump, producing long lasting suppression of gastric acid secretion.
Act irrespective of stimulus as do not act on receptors. - 5What is the class and MOA for: Cimetidine, Famotidine, Nizatidine and RanitidineClass: H2 receptor antagonist
MOA: Competitively antagonist of histamine H2 receptor, inhibiting the action of the H2 receptor at the parietal cell reducing secretion of gastric acid - 6Protein pump inhibitor Adverse EffectsHeadache, n&v, diarrhoea, abdo pain, constipation, flatulence
Long term: osteoporosis, VB12 deficiency - 7Lifestyle changes for GORD1. Reduce alcohol intake and cease smoking
