Do You Know They Are Used For Rhinitis?

Rhinitis refers to inflammation of the nasal passages. This inflammation can cause a variety of annoying symptoms, including sneezing, itching, nasal congestion, runny nose, and post-nasal drip (the sensation that mucus is draining from the sinuses down the back of the throat). www.ebiochem.com

Brief episodes of rhinitis are usually caused by respiratory tract infections with viruses (eg, the common cold). Chronic rhinitis is usually caused by allergies, but it can also occur from overuse of certain drugs, some medical conditions, and other unidentifiable factors. www.ebiochem.com

Allergic rhinitis is caused by a nasal reaction to small airborne particles called allergens (substances that provoke an allergic reaction). In some people, these particles also cause reactions in the lungs (asthma) and eyes (allergic conjunctivitis).

The allergic reaction is characterized by activation of two types of inflammatory cells, called mast cells and basophils. These cells produce inflammatory substances, such as histamine, which cause fluid to build up in the nasal tissues (congestion), itching, sneezing, and runny nose. Over several hours, these substances activate other inflammatory cells that can cause persistent symptoms. www.ebiochem.com

Chlorpheniramine

Chlorphenamine (INN) or chlorpheniramine (USAN, former BAN), commonly marketed in the form of chlorpheniramine maleate (Chlorphen-12[1]), is a first-generation alkylamine antihistamine used in the prevention of the symptoms of allergic conditions such as rhinitis and urticaria. Chlorpheniramine relieves red, itchy, watery eyes; sneezing; itchy nose or throat; and runny nose caused by allergies, hay fever, and the common cold.
