Chlorpheniramine Maleate Salt is widely used as an antihistamine to alleviate symptoms associated with allergic reactions, such as hay fever, rhinitis, and conjunctivitis. It effectively reduces sneezing, itching, watery eyes, and runny nose by blocking the action of histamine in the body. Additionally, it is commonly included in cold and flu medications to relieve nasal congestion and other respiratory symptoms. In some formulations, it is combined with decongestants or pain relievers for enhanced efficacy. It is also utilized in veterinary medicine to treat allergic conditions in animals. The compound is typically administered orally in tablet or liquid form, and in some cases, as an injectable solution for more severe allergic reactions.
