(8) in H4 receptor-knockout mice showed that these receptors modulate various neurophysiological functions, such as anxiety, locomotor activity, and nociception, indicating the importance of the integrity and functionality of the H4 receptors in the histaminergic regulation of neuronal functions.
In Europe, the most frequently prescribed drug in the treatment of MD is betahistine, a weak H1 agonist and strong H3 antagonist histaminergic molecule [18].

Neuromodulation and the waking state are related to histaminergic neurons.
Drug-induced histamine release from mast cells/ basophils occurs as a result either of an IgE-dependent allergic reaction or of direct IgE-independent degranulation of these cells resulting in histaminergic angioedema.
Agonists (acetylcholine, histamine) and their appropriate antagonists (atropine, H1 blocker-pheniramine maleate) were used to evaluate the cholinergic and histaminergic mechanisms.

This result may be due to serotonin modulation as mentioned above or some other mechanisms including histaminergic receptors.
Pimavanserin, a selective 5-HT2A inverse agonist without dopaminergic, adrenergic, histaminergic, or muscarinic effect [141], has been approved by the FDA [142] in September 2014 and has shown to be effective and safe in the treatment of PD psychosis, reducing hallucinations and delusions without affecting motor function [143, 144], which is a commonly observed drawback of most antipsychotic drugs due to dopamine antagonism.
It is therefore reasonable to propose that the extract may act directly on the histaminergic receptor or in its signaling pathway, since the effect on the muscarinic (M3) and [Ca.sup.2+] influx through VACCs was not altered by the presence of the extract.
