| 生物活性 | Terfenadine is a prodrug that is metabolized by intestinal CYP3A4 to the active form fexofenadine, a selective histamine H1-receptor antagonist with antihistaminic and non-sedative effects. Terfenadine's active metabolite competitively binds peripheral H1-receptors, thereby stabilizing an inactive conformation of the receptor. Consequently, usual allergic responses as a result of mast-cell degranulation followed by the release of multiple inflammatory mediators, such as interleukins, prostaglandins, and leukotriene precursors, are blocked, thereby preventing the triggering of pro-inflammatory pathways. | ||
