Chlorpheniramine is an old medicine that is utilized to hold in check the symptoms of allergy to the upper signs caused by hay fever and the common cold. It helps stop watery eyes and incessant sneezing. The efficacy of chlorpheniramine is harnessed through an action against histamine, one that belongs to an endogenous hormone group: histamine-induced allergic responses. Its air-drying ability also helps blistering symptoms.
Important Therapeutic Uses
• Allergic Rhinitis: Rapidly switches off pruritus, coughing, and sneezing induced by pollen, dust, or pet hair.
• Hives (Urticaria): Reduces redness, swelling, and intense itchiness due to young skin rashes.
• Common Cold Setting Ships: Used in a number of cold formulas for controlling “runny nose” and post-nasal drip.
• Conjunctivitis: Calms itching, red, and watery eyes related to environmental allergens.
How It Works
Your immune system only produces histamine to combat allergens. Once released, histamine binds with H1 receptors, which cause inflammation and other signs initiated by the release of body fluids. Chlorpheniramine locks onto the H1 receptors (ie., is an H1-receptor antagonist), which thus prevent histamine from getting stuck there. This way, some affected tissues become stabilized and the allergic reaction is stopped.
