My favorite organic chemical is the antihistamine Allegra. Scientifically known as Fexofenadine, Allegra is a hydrochloride salt used for the relieve of Hay Fever, and chronic idiopathic urticaria (Hives).1 Allegra is my favorite organic compound because, personally, I have had seasonally allergies since middle school and my doctor recommended I try taking Allegra to subside my allergy symptoms of a runny nose and nasal congestion. Allegra works greatly for my allergy symptoms. It is so effective, in fact, that my sister also takes Allegra for her seasonal allergies as well. Created by Marion Merrel Dow, fexofenadine was made to be the metabolite of terfenadine. Dow chose to do this because of his wanting to change the growth of generic products constructed upon terfenadine.2 According to Dow, fexofenadine is called a second generation histamine blocker, disallowing the activation of H1 receptors. A benefit of Allegra is that it does not easily go into the brain via the bloodstream in the human body.
