proton pump inhibitor

agents that block the transport of hydrogen ions into the stomach and hence are useful in the treatment of gastric hyperacidity.

proton pump inhibitor

n. Any of a class of drugs that inhibit gastric acid secretion by interfering with the movement of hydrogen ions across cell membranes and are used mainly to treat peptic ulcers and gastroesophageal reflux disease.

proton pump inhibitor

An agent—e.g., Prilosec (omeprazole))—used to reduce gastric acid production in patients with dyspepsia, peptic ulcer disease, gastrooesophageal reflux disease, Barrett’s disease, and other conditions.
Adverse effects
Hip fracture, Clostridium difficile infection, hypomagnesaemia and acute interstial nephritis.

proton pump inhibitor

Pharmacology A compound–eg, Prilosec– omeprazole that is better than H2 blockers–eg, Zantac–ranitidine, Tagamet– cimetidine, for treating GERD. See Gastroesophageal reflux disease. Cf H2 blockers.

pro·ton pump in·hib·i·tor

(prō'ton pŭmp in-hib'i-tŏr) An agent that blocks the transport of hydrogen ions into the stomach and henceis useful in the treatment of gastric hyperacidity, as observed in ulcer disease.

proton pump inhibitor

One of a class of drugs that interfere with the action of the proton pump responsible for the synthesis of hydrochloric acid in the parietal cells of the stomach lining. The proton pump is the enzyme H+, K+ -ATPase and this can be blocked by drugs such as OMEPRAZOLE (Losec).
