What are H2 antagonists
H2 antagonists competitively inhibits histamine at the H2 receptors and leads to a reduction in secretion of gastric acid.
Histamine stimulates the secretion of gastric acid by action on H2 receptors, which are found in the parietal cells of the gastric mucosa.
H2 antagonists are used to treat gastroesophageal reflux disease (GERD), gastrointestinal ulcers and other gastrointestinal hypersecretory conditions.
