Cloperastine fendizoate is primarily used as an antitussive agent, effectively reducing coughing by acting on the cough center in the brain. It is commonly prescribed for the treatment of dry, non-productive coughs associated with conditions such as colds, bronchitis, or other respiratory tract infections. The compound works by suppressing the cough reflex, providing relief and improving comfort for patients. It is often formulated in syrups or tablets for oral administration, making it convenient for both adults and children. Due to its effectiveness and relatively mild side effect profile, it is widely utilized in clinical settings for managing cough symptoms.
