CAS 153439-40-8: Fexofenadine hydrochloride

Description: Fexofenadine hydrochloride is an antihistamine medication primarily used to alleviate allergy symptoms, such as hay fever and hives. It is classified as a second-generation antihistamine, which means it is less likely to cause sedation compared to first-generation antihistamines. The substance is a white to off-white crystalline powder that is soluble in water and exhibits a pH range of 4.5 to 6.5 in solution. Its molecular formula is C32H39NO4S, and it has a molecular weight of approximately 501.73 g/mol. Fexofenadine works by selectively blocking peripheral H1 receptors, thereby inhibiting the effects of histamine, a compound involved in allergic reactions. The drug is typically administered orally and is known for its rapid onset of action and prolonged duration of effect. Additionally, it has a favorable safety profile, with minimal interactions with other medications and a low incidence of side effects. Overall, fexofenadine hydrochloride is an effective option for managing allergic conditions.
