In vitro study | Pheniramine Maleate is a histamine H1 antagonist with no sedative effect. It is used to treat pollinosis, rhinitis, allergic skin diseases, and pruritus. Pheniramine acts on the histamine H1 receptor site on the cell in competition with histamine to produce an effect. Antihistamines antagonize the pharmacological effects of histamine by activating H1 receptor-mediated sites, thereby reducing the intensity of allergic reactions and responses to tissue damage. Antihistamines inhibit histamine-induced vesicular (swelling) and flare (vasodilation) responses by blocking the binding of histamine to its receptors on nerves, vascular smooth muscle, glandular cells, endothelial cells and mast cells. They act on the H1-receptor and effectively exert a competitive antagonistic action against histamine. |
