Application
Terfenadine: A Prodrug of Fexofenadine with Selective H1-Receptor Antagonist Activity
Terfenadine is a prodrug of fexofenadine [F0698] (HCl salt) which is a non-sedative antihistamine with selective H1-receptor antagonist activity. Terfenadine is metabolized by intestinal CYP3A4 to fexofenadine which 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. In addition, it has been reported that terfenadine may reach excessive blood levels when the metabolism is too slow; and which can cause cardiac arrhythmias (prolongation of QT-interval). (The product is for research purpose only.)
