Zaditen, known generically as ketotifen, is a medication primarily used in the management and prevention of asthma symptoms and for the treatment of allergic conditions, including rhinitis and conjunctivitis. It functions as a mast cell stabilizer and an antihistamine, which helps to reduce inflammation and the severity of allergic reactions. Zaditen works by blocking histamine and other substances that contribute to allergic responses, thereby alleviating symptoms such as sneezing, itching, watery eyes, and runny nose. It is available in various forms, including tablets, eye drops, and syrup, making it suitable for both adults and children. Due to its mechanism of action, Zaditen is often used as a long-term treatment option for individuals with chronic allergic conditions and asthma.
