Antihistamine - H2-receptor antagonists
Main article: H2-receptor antagonist
Clinically-relevant histamine H2-receptors are found principally in the parietal cells of the gastric mucosa. H2-receptor "antagonists" are also inverse agonists, rather than true antagonists; and are used to reduce the secretion of gastric acid. Examples include cimetidine, ranitidine, and famotidine.
Antihistamine - H3- and H4-receptor antagonists
These are experimental agents and do not yet have a defined clinical use.
- Thioperamide
- Clobenpropit
- Impromidine
-
- Similar in structure to burimamide
- imidazole ring
- Polar moiety on the side chain - thiourea, isothiourea and guanidine
- other substituents are highly variable
Antihistamine - Other agents with antihistaminergic activity
Many drugs, used for other indications, possess unwanted antihistaminergic activity. These include tricyclic antidepressants, antipsychotics, etc.
