Histamine H2 Antagonists
MeSH HeadingHistamine H2 Antagonists
Tree NumberD27.505.519.625.375.425.425
Tree NumberD27.505.696.577.375.425.425
AnnotationGEN or unspecified; prefer specifics; DF: HISTAMINE H2 ANTAG
Scope NoteDrugs that selectively bind to but do not activate histamine H2 receptors, thereby blocking the actions of histamine. Their clinically most important action is the inhibition of acid secretion in the treatment of gastrointestinal ulcers. Smooth muscle may also be affected. Some drugs in this class have strong effects in the central nervous system, but these actions are not well understood.
