Mizolastine dihydrochloride is primarily used as an antihistamine in the treatment of allergic conditions. It is effective in alleviating symptoms of allergic rhinitis, such as sneezing, nasal congestion, and runny nose, as well as managing symptoms of chronic urticaria, including itching and hives. The compound works by selectively blocking histamine H1 receptors, reducing the body's allergic response. It is often preferred due to its non-sedating properties, making it suitable for individuals who need to maintain alertness during daily activities. Additionally, it has anti-inflammatory effects, which further contribute to its efficacy in managing allergic reactions. Mizolastine dihydrochloride is typically administered orally and is available in tablet form for convenient use.
