Betazole is used as a stimulant in preference to histamine because of its specificity for the H 2 receptor and its advantage of not generating the undesirable side effects that histamine would induce. It therefore does not require concomitant use of antihistaminic compounds to block the actions of histamine at other histamine receptor types.
Histaminergic means "working on the histamine system", and histaminic means "related to histamine". [1] A histaminergic agent (or drug) is a chemical which functions to directly modulate the histamine system in the body or brain. Examples include histamine receptor agonists and histamine receptor antagonists (or antihistamines).
During that time, many dietitians advised that a diet devoid of histamine-liberating foods was the ideal strategy to prevent symptoms of histamine intolerance from manifesting. Lists of foods deemed to be histamine-liberating were published in various scientific articles, which included fermented sausages, cured cheese, wine and beer. [11]

[1] H 2: Betazole and Impromidine are examples of agonists used in diagnostics to increase histamine. H 3: Betahistine is a weak Histamine 1 agonist and a very strong antagonist of the Histamine ...
It is an inverse agonist of the histamine H 3 receptor. [3] It represents the first commercially available medication in its class, so that the U.S. Food and Drug Administration (FDA) declares it a first-in-class medication. [7] [8] Pitolisant enhances the activity of histaminergic neurons in the brain that function to improve a person's ...
Antihistamines are drugs which treat allergic rhinitis, common cold, influenza, and other allergies. [1] Typically, people take antihistamines as an inexpensive, generic (not patented) drug that can be bought without a prescription and provides relief from nasal congestion, sneezing, or hives caused by pollen, dust mites, or animal allergy with few side effects.

While histamine has stimulatory effects upon neurons, it also has suppressive ones that protect against the susceptibility to convulsion, drug sensitization, denervation supersensitivity, ischemic lesions and stress. [36] It has also been suggested that histamine controls the mechanisms by which memories and learning are forgotten. [37]
