CAS 174483-06-8: Ethyl Fexofenadine

Description: Ethyl fexofenadine is an antihistamine compound primarily used for the treatment of allergic conditions such as hay fever and urticaria. It is a derivative of fexofenadine, which is a well-known second-generation antihistamine. Ethyl fexofenadine exhibits selective antagonism of peripheral H1 receptors, which helps alleviate symptoms associated with allergic reactions without causing significant sedation, a common side effect of first-generation antihistamines. The compound is characterized by its relatively low solubility in water, which influences its pharmacokinetic properties, including absorption and distribution in the body. Ethyl fexofenadine is typically administered orally and is metabolized in the liver, with its metabolites excreted primarily through urine. Its safety profile is generally favorable, with a low incidence of adverse effects. As with any medication, it is essential to consider potential drug interactions and contraindications when prescribing or using ethyl fexofenadine. Overall, it represents a valuable option in the management of allergic symptoms, contributing to improved patient quality of life.
