Drug to increase activity at histamine receptors
A histamine agonist is a drug which causes increased activity at one or more of the four
histamine receptor subtypes.
H2:
Betazole and
Impromidine are examples of agonists used in diagnostics to increase histamine.
H3:
Betahistine is a weak Histamine1 agonist and a very strong antagonist of the Histamine3
autoreceptor. Antagonizing H3 increases histaminergic tone.
