Antibiotics for peptic ulcer disease
Amoxicillin, bismuth, clarithromycin, metronidazole, tetracycline, tinidazole
Expected action of peptic ulcer antibiotics
eradication of H. pylori bacteria
Common adverse effect of peptic ulcer antibiotics
nausea and diarrhea
Histamine2-receptor antagonists med
Cimetidine
Expected action of cimetidine
Block H2 receptors which suppresses secretion of gastric acid and lowers the concentration of hydrogen ions in the stomach
Use of cimetidine
gastric and duodenal ulcers, GERD, heartburn, Zollinger-Ellison syndrome, acid indigestion, and used in conjunction with antibiotics to treat ulcers caused by H. pylori
Complications of cimetidine
blocked androgen receptors, CNS effects, constipation, diarrhea, and nausea
Interactions of cimetidine
smoking, warfarin, phenytoin, theophylline, lidocaine, and antacids
Contraindications of cimetidine
kidney impairment
proton pump inhibitors med
omeprazole (end in -zole)
expected action of omeprazole
block basal and stimulated acid production and reduce gastric acid secretion by irreversibly inhibiting the enzyme that produces gastric acid
use of omeprazole
short-term therapy of gastric and duodenal ulcers, erosive esophagitis, and GERD, long-term therapy of hypersecretory conditions, prevention of stress ulcers
complications of omeprazole
pneumonia, osteoporosis, fractures, rebound acid hypersecretion, hypomagnesemia, C. diff diarrhea
How long should omeprazole be used?
4-6/8 weeks
Interactions of omeprazole
digoxin, methotrexate, diazepam, tacrolimus, antifungal agents, phenytoin, ketoconazole, itraconazole, atazanavir, and clopidogrel
When should omeprazole be taken?
Once in the morning before breakfast
Antacid meds
aluminum hydroxide, magnesium hydroxide, and calcium carbonate
expected action of antacids
neutralize or reduce the acidity of gastric acid, can reduce pepsin activity if pH is raised above 5, mucosal protection can occur from stimulation of the production of prostaglandins
use of antacids
tx of peptic ulcer disease, prevention of stress-induced ulcers, and relief of manifestations of GERD
complications of antacids
aluminum and calcium compounds: constipation; magnesium compounds: diarrhea; fluid retention, alkalosis, toxicity, hypermagnesemia; aluminum: hypophophatemia; calcium: hypercalcemia
interactions of antacids
famotidine, cimetidine, warfarin, digoxin, and tetracycline
when should antacids be administered?
7 times a day: 1 hr and 3hrs after meals, again at bedtime
nursing administration for antacids
chew tablets thoroughly and then drink a glass of water, take all medications at least 1 hr before or after taking an antacid
prostaglandin e analog meds
misoprostol
