Chlorpheniramine Maleate is a first-generation antihistamine commonly used to treat:
1. Allergic rhinitis (hay fever)
2. Urticaria (hives)
3. Common cold symptoms (e.g. sneezing, runny nose)
4. Itching and other allergic skin reactions
It works by blocking H1 histamine receptors, thereby reducing the effects of natural histamine in the body. Unlike second-generation antihistamines, chlorpheniramine crosses the blood-brain barrier, often causing drowsiness and sedation.
