| Description | Pheniramine maleate (Trimetose), an alkylamine derivative with antihistaminic and vasodilatory properties, binds to histamine H1 receptors, thereby inhibiting phospholipase A2 and production of the endothelium-derived relaxing factor, nitric oxide. |
| Targets&IC50 | H1 Receptor:1.01 mM |
| In vivo | Pheniramine maleate binds to histamine H1 receptors, which inhibits the production of phospholipase A2 and the endothelium-derived relaxing factor NO. This leads to a reduction in the activation of guanylate cyclase due to NO deficiency, resulting in decreased levels of cyclic GMP (cGMP). Consequently, this suppresses the contraction of smooth muscle tissues, reduces capillary permeability, and diminishes histamine-induced allergic responses. |
