Introduction
Azelastine HCL is a commonly used medication for the treatment of allergic rhinitis. It belongs to a class of drugs known as antihistamines and is available both as a prescription and over the counter (OTC) medication. In this article, we will explore what Azelastine HCL is, how it works, its indications and usage, potential side effects, precautions, dosage, and administration, as well as over-the-counter options.
What is Azelastine HCL?
Azelastine HCL is an antihistamine that is used to relieve symptoms of seasonal and perennial allergic rhinitis, such as a runny or stuffy nose, sneezing, and itching. It works by blocking the effects of histamine, a substance that is released by the body during an allergic reaction. By blocking histamine, Azelastine HCL helps to reduce symptoms associated with allergies.
How Does Azelastine HCL Work?
Azelastine HCL works by blocking the H1 histamine receptors in the body. When an allergen triggers an allergic reaction, the body releases histamine, which binds to these receptors and causes symptoms like sneezing, itching, and a runny nose. By blocking the H1 receptors, Azelastine HCL prevents the histamine from binding, thus reducing the allergic response and relieving symptoms.
