Pharmacology

Indication

For the treatment of peptic ulcer disease (PUD) and gastroesophageal reflux disease (GERD).

Structured Indications

Pharmacodynamics

Famotidine, a competitive histamine H₂-receptor antagonist, is used to treat gastrointestinal disorders such as gastric or duodenal ulcer, gastroesophageal reflux disease, and pathological hypersecretory conditions. Famotidine inhibits many of the isoenzymes of the hepatic CYP450 enzyme system. Other actions of Famotidine include an increase in gastric bacterial flora such as nitrate-reducing organisms.

Mechanism of action

Famotidine binds competitively to H₂-receptors located on the basolateral membrane of the parietal cell, blocking histamine affects. This competitive inhibition results in reduced basal and nocturnal gastric acid secretion and a reduction in gastric volume, acidity, and amount of gastric acid released in response to stimuli including food, caffeine, insulin, betazole, or pentagastrin.

Targets

Details

1. Histamine H2 receptor

Kind: Protein
Organism: Human
Pharmacological action: yes
Actions: antagonist

General Function:: Histamine receptor activity
Specific Function:: The H2 subclass of histamine receptors mediates gastric acid secretion. Also appears to regulate gastrointestinal motility and intestinal secretion. Possible role in regulating cell growth and differentiation. The activity of this receptor is mediated by G proteins which activate adenylyl cyclase and, through a separate G protein-dependent mechanism, the phosphoinositide/protein kinase (PKC) si...
Gene Name:: HRH2
Uniprot ID:: P25021
Molecular Weight:: 40097.65 Da
