VIII. Precautions: General

  1. Longterm Proton Pump Inhibitor use has significant risks (see adverse effects below)
    1. Avoid >8 weeks of use in elderly (unless serious esophageal reflux, Barrett's Esophagus)
  2. Maximize non-pharmacologic measures (e.g. GERD precautions)
    1. Avoid Alcohol, Tobacco, NSAIDs
    2. Reduce the need for longterm Proton Pump Inhibitor
  3. Balance adverse effects against the risks of discontinuing acid suppression
    1. Barrett's Esophagus requires longterm Proton Pump Inhibitor
      1. Acid suppression to prevent progression to Esophageal Cancer
    2. Hiatal Hernia will likely require longterm Proton Pump Inhibitors
  4. Use the lowest effective dose and for the shortest duration that controls symptoms
    1. Consider discontinuation protocol below
    2. Consider less complete acid suppression (e.g. H2 Blocker)
    3. Consider limited 4 week course of PPI for Duodenal Ulcer
    4. Consider limited 8 week course of PPI for Erosive Gastritis or Gastric Ulcer
      1. Then taper to other acid suppression (e.g. H2 Blocker)
    5. Consider brief intermittent use (e.g. 2-4 weeks) for exacerbations

IX. Precautions: Pregnancy and Lactation

  1. Pregnancy Category C: Omeprazole
  2. Pregnancy Category B: Other agents

X. Protocol: Discontinuation

  1. Indications
    1. Recurrence of GERD or Gastritis symptoms on abruptly stopping Proton Pump Inhibitor
  2. Use H2 Blocker (e.g. Ranitidine) when symptoms arise on days a Proton Pump Inhibitor is not taken
  3. Taper over 4-6 weeks
    1. If taking twice daily, shift to once daily
    2. Next, take every other day
    3. Then, take every third day
    4. Then, continue to increase the interval between doses

XI. Lab: Monitoring for longterm Proton Pump Inhibitor

  1. Serum Creatinine annually
  2. Serum Vitamin B12 level every 5 years
  3. Serum Magnesium if symptoms present
  4. Complete Blood Count every 2 years

Ontology: Omeprazole (C0028978)

Definition (MSH) A 4-methoxy-3,5-dimethylpyridyl, 5-methoxybenzimidazole derivative of timoprazole that is used in the therapy of STOMACH ULCERS and ZOLLINGER-ELLISON SYNDROME. The drug inhibits an H(+)-K(+)-EXCHANGING ATPASE which is found in GASTRIC PARIETAL CELLS.
Definition (NCI) A benzimidazole with selective and irreversible proton pump inhibition activity. Omeprazole forms a stable disulfide bond with the sulfhydryl group of the hydrogen-potassium (H+ - K+) ATPase found on the secretory surface of parietal cells, thereby inhibiting the final transport of hydrogen ions (via exchange with potassium ions) into the gastric lumen and suppressing gastric acid secretion. This agent exhibits no anticholinergic activities and does not antagonize histamine H2 receptors.
Definition (NCI_NCI-GLOSS) A drug that inhibits gastric acid secretion.
Definition (CSP) substituted benzimidazole used as a gastric acid secretion inhibitor.
Definition (PDQ) A benzimidazole with selective and irreversible proton pump inhibition activity. Omeprazole forms a stable disulfide bond with the sulfhydryl group of the hydrogen-potassium (H+ - K+) ATPase found on the secretory surface of parietal cells, thereby inhibiting the final transport of hydrogen ions (via exchange with potassium ions) into the gastric lumen and suppressing gastric acid secretion.

Definition (MSH) A 2,2,2-trifluoroethoxypyridyl derivative of timoprazole that is used in the therapy of STOMACH ULCERS and ZOLLINGER-ELLISON SYNDROME. The drug inhibits H(+)-K(+)-EXCHANGING ATPASE which is found in GASTRIC PARIETAL CELLS. Lansoprazole is a racemic mixture of (R)- and (S)-isomers.
Definition (NCI) A substituted benzimidazole prodrug with selective and irreversible proton pump inhibitor activity. Lansoprazole prodrug is converted to an active sulfonamide derivative in the acidic environment of the gastric parietal cell; the sulfonamide derivative binds to the gastric proton pump H+/K+ ATPase and forms a stable disulfide bond with the sulfhydryl group near the potassium-binding site on the luminal side, resulting in inactivation of the ATPase and a reduction in gastric acid secretion. This agent does not have anticholinergic or histamine H2 -receptor antagonistic properties.

Ontology: pantoprazole (C0081876)

Definition (NCI) A substituted benzimidazole and proton pump inhibitor with antacid activity. Pantoprazole is a lipophilic weak base that crosses the parietal cell membrane and enters the acidic parietal cell canaliculus where it becomes protonated, producing the active metabolite sulphenamide, which forms an irreversible covalent bond with two sites of the H+/K+-ATPase enzyme located on the gastric parietal cell, thereby inhibiting both basal and stimulated gastric acid production.

Definition (MSH) A 4-(3-methoxypropoxy)-3-methylpyridinyl derivative of timoprazole that is used in the therapy of STOMACH ULCERS and ZOLLINGER-ELLISON SYNDROME. The drug inhibits H(+)-K(+)-EXCHANGING ATPASE which is found in GASTRIC PARIETAL CELLS.
Definition (NCI) An alpha-pyridylmethylsulfinyl benzimidazole and a selective and irreversible proton pump inhibitor with antisecretory property. Rabeprazole enters the parietal cell and accumulates in the acidic secretory canaliculi where the agent is activated by a proton-catalyzed process that results in the formation of a thiophilic sulfonamide or sulfenic acid. The activated rabeprazole forms covalent bonds with the sulfhydryl amino acids cysteine on the extracellular domain of the proton pump (H+/K+ ATPase) at the secretory surface, thereby inhibiting the transport of hydrogen ions, via exchange with potassium ions, into the gastric lumen. Binding to cysteine 813, in particular, is essential for inhibition of gastric acid production.

Definition (NCI_NCI-GLOSS) A drug that blocks acid from being made in the stomach. It is used to treat acid reflux disease and to prevent certain types of gastrointestinal ulcers. Esomeprazole is being studied in the prevention of esophageal cancer and in the treatment of other conditions, including side effects of chemotherapy. It is a type of anti-ulcer agent.
Definition (NCI) The S-isomer of omeprazole, with gastric proton pump inhibitor activity. In the acidic compartment of parietal cells, esomeprazole is protonated and converted into the active achiral sulfenamide; the active sulfenamide forms one or more covalent disulfide bonds with the proton pump hydrogen-potassium adenosine triphosphatase (H+/K+ ATPase), thereby inhibiting its activity and the parietal cell secretion of H+ ions into the gastric lumen, the final step in gastric acid production. H+/K+ ATPase is an integral membrane protein of the gastric parietal cell.
