<unk>  is a selective antihistamine – that is, an inverse agonist of the histamine H1 receptor (Ki = 0.166 nM) – and mast cell stabilizer. In addition,<unk>  has weak anticholinergic (Ki = 204 nM for ) and antiserotonergic (Ki = 38.9 nM for 5-HT2A) activity. However, at the dosages in which it is typically used clinically, both the anticholinergic and antiserotonergic activity of<unk>  are said not to be appreciable.
