completely blocks the H2 receptor of acid producing parietal cells, making the parietal cells less
responsive to histamine and stimulation of gastrin
H2 receptor antagonist meds
cimetidine, ranitidine, famotidine, nizatidine
H2 receptor antagonist indications
Gerd, peptic ulcer disease, erosive esophagitis, adjunct therapy in control of upper GI tract bleeding,
tx of pathologic gastic hypersecretory conditions, zollinger-ellison syndrome, stress ulcer prophylaxis

liver and kidney dysfunctions
H2 receptors antagonists adverse effects
-low incidence
-headache, lethargy, confusion, depression, diarrhea, nausea, cramping
ranitidine danger
potentially causes cancer
proton pump inhibitors (PPIs) action

, STUVIA

directly binds with hydrogen potassium ATPase pump mechanism and irreversibly inhibits the action
of the enzyme, resulting in blocking hydrogen ion secretion from the parietal cells
PPI meds
lansoprazole, omeprazole, rabeprazole, pantoprazole, esomeprazole
PPI indications
first line for erosive esophagitis, GERD poorly responsive to other treatment, short term tx of active
duodenal ulcers and gastric ulcers, zollinger-ellison syndrome, NSAID induced ulcers, stress ulcer

-classified as an anti-flatulent drug
all antacids should be taken
with 8 oz of water to ensure absorption, 2 hours before or after other meds due to altering med
absorption
nursing care for H2 receptor antagonists
assess renal and liver functions, level of consciousness
PPI nursing care
-give on empty stomach 30min-1hour before meals
-assess pts for manifestations of osteoporosis or hx of disorder
contact HCP immediately when taking acid controlling drugs if
severe constipation or diarrhea, increase in abdominal pain, abdominal distention, hematemesis,
