Description and Uses
Betahistine is an analogue of histamine with weak agonist properties at histamine H1 receptors and more potent antagonistic effects at histamine H3 receptors.
This drug is broadly used worldwide, except for the USA, since it has not been approved by the US Food and Drug Administration. Betahistine is a structural analog of histamine that acts as a weak partial postsynaptic histamine H1 receptor agonist and presynaptic H3 receptor antagonist, with no effect on postsynaptic H2 receptors (Gbahou et al, 2010). The mechanism of action of the drug appears to depend mainly on its action on H3 receptors mediated by two metabolites, aminoethylpyridine and hydroxyethylpyridine (Bertich et al, 2014).
