What is Fexofenadine?

Fexofenadine is a selective histamine 1 receptor that resides inside our bodies; however, it is not present in the central nervous system. known as the peripheral receptors for histamine. Because it works on the receptors that it targets, fexofenadine is far less likely to cause somnolence than some of the older antihistamines.

Histamine is a substance that mast cells release when they are exposed to allergens, and it causes numerous allergy-related symptoms, including watery eyes, nasal congestion, or sneezing. Itching is also a common symptom. Fexofenadine is a binder to the histamine receptors and blocks histamine from having an impact on the receptors. This reduces the severity of the symptoms of allergies.

There are a variety of types and varieties of fexofenadine available.Fexofenadine was accepted by the FDA in 1996.
