Mechanism of Action
Fexofenadine is a second-generation selectively peripheral H1-blocker of the GI tract, large blood vessels, and bronchial smooth muscle. Blockage prevents the activation of the H1 receptors by histamine, preventing the symptoms associated with allergies from occurring. Fexofenadine cannot cross the blood–brain barrier and therefore does not cause drowsiness. It also exhibits no anticholinergic, antidopaminergic, alpha1-adrenergic, or beta-adrenergic-receptor-blocking effects.

Famous quotes containing the words mechanism of, mechanism and/or action:
“The two elements the traveler first captures in the big city are extrahuman architecture and furious rhythm. Geometry and anguish. At first glance, the rhythm may be confused with gaiety, but when you look more closely at the mechanism of social life and the painful slavery of both men and machines, you see that it is nothing but a kind of typical, empty anguish that makes even crime and gangs forgivable means of escape.”
—Federico García Lorca (1898–1936)

“We have seen the city; it is the gibbous
Mirrored eye of an insect. All things happen
On its balcony and are resumed within,
But the action is the cold, syrupy flow
Of a pageant.”
—John Ashbery (b. 1927)
