On both cards: Common side effects — Diarrhea; Abdominal pain; Flatulence
Only on the Omeprazole card: Used for — Short-term treatment of active duodenal or benign gastric ulcer in adults; H. pylori eradication with the specified antibiotics in adults with duodenal ulcer disease; Short-term symptomatic GERD or erosive esophagitis treatment, and maintenance of healed erosive esophagitis, in patients aged 2 years and older; Long-term treatment of pathological hypersecretory conditions in adults · Common side effects — Headache; Nausea · Warnings — Acute tubulointerstitial nephritis; C. difficile-associated diarrhea; Bone fracture with long-term use
Mechanism: Converted in the parietal cell to an active inhibitor that blocks the H+/K+ ATPase (proton pump), suppressing gastric acid secretion.
On both cards: Common side effects — Diarrhea; Abdominal pain; Flatulence
Only on the Esomeprazole magnesium card: Used for — Short-term erosive-esophagitis healing in adults and ages 12–17; maintenance of healing in adults; Short-term heartburn and other GERD symptoms in adults and ages 12–17; Reduce NSAID-associated gastric-ulcer risk in adults receiving continuous NSAIDs who are aged 60 or older and/or have a documented gastric-ulcer history; With amoxicillin and clarithromycin, eradicate H. pylori in adults with active duodenal ulcer or a history within 5 years to reduce recurrence · Common side effects — Headache; Nausea · Warnings — C. difficile-associated diarrhea; Bone fracture with long-term use; Acute tubulointerstitial nephritis
Mechanism: Covalently binds the H+/K+ ATPase of the gastric parietal cell, suppressing the final step of acid production, basal and stimulated.
On both cards: Common side effects — Diarrhea; Abdominal pain
Only on the Pantoprazole card: Used for — Short-term healing and symptom relief of GERD-associated erosive esophagitis in adults and children aged 5 years and older; Maintenance of healed erosive esophagitis and reduction of heartburn relapse in adults with GERD; Long-term treatment of pathological hypersecretory conditions, including Zollinger-Ellison syndrome, in adults · Common side effects — Headache; Nausea · Warnings — C. difficile-associated diarrhea; Bone fracture with long-term use; Vitamin B12 deficiency
