|Drug Class: What is Fexofenadine and why is it prescribed?|
Fexofenadine, is an oral, \"second generation\" antihistamine that is used to treat the signs and symptoms of allergy that are due to histamine.
Fexofenadine relieves the itchy, runny nose, sneezing, and itchy, red, watery
eyes that come with hay fever. Its effect begins in 1 hour and lasts 12 hours,
peaking around the second or third hour.
|Drug Mechanism: How does Fexofenadine work?|
Fexofenadine, is similar to the other second generation antihistamines loratadine (Claritin), cetirizine (Zyrtec) and azelastine (Astelin). Histamine is a chemical in the body that stimulates the production of mucus and the dilation
of blood vessels.
Fexofenadine blocks one type of receptor for histamine (the H1 receptor) and thus prevents activation of H1 receptor-containing cells by histamine. Unlike the first generation antihistamines, and other second-generation antihistamines do not readily enter the brain from the blood, and, therefore, they cause less drowsiness.
Fexofenadine, was approved by the FDA in July, 1995.
