Azelastine HCl nasal spray is a widely used medication for the treatment of allergic rhinitis, a condition characterized by symptoms such as nasal congestion, sneezing, runny nose, and itchy nose. As an antihistamine, azelastine HCl works by blocking the action of histamine, a chemical released by the body's immune system during an allergic reaction. In this article, we will explore the benefits and efficacy of azelastine HCl nasal spray in providing relief from allergies.
What is Azelastine HCl Nasal Spray?
Azelastine HCl nasal spray is a topical medication that is administered directly into the nostrils. It is available over-the-counter (OTC) and by prescription, depending on the strength and formulation. The medication is commonly used to treat seasonal and perennial allergic rhinitis, as well as non-allergic rhinitis.
How Does Azelastine HCl Nasal Spray Work?
Azelastine HCl nasal spray works by blocking the histamine H1 receptors in the nasal passages, which are responsible for triggering allergic symptoms. By blocking these receptors, the medication prevents histamine from binding and causing an allergic response. This results in a reduction of symptoms such as nasal congestion, sneezing, and runny nose.
