(R,R)-Formoterol is primarily used as a long-acting beta-2 adrenergic agonist (LABA) in the management of respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). It works by relaxing the muscles in the airways, which helps to improve breathing and reduce symptoms like wheezing, shortness of breath, and coughing.

This compound is often administered via inhalation, either through a metered-dose inhaler or a dry powder inhaler, ensuring direct delivery to the lungs for rapid and effective action. It is commonly used in combination with inhaled corticosteroids to provide both immediate and long-term control of asthma symptoms, reducing the frequency and severity of asthma attacks.

In COPD, (R,R)-Formoterol helps to alleviate breathing difficulties and improve exercise tolerance, enhancing the overall quality of life for patients. Its long-acting nature allows for twice-daily dosing, making it convenient for long-term management of these chronic respiratory conditions.

Additionally, (R,R)-Formoterol is sometimes used off-label in other conditions where bronchodilation is beneficial, though its primary application remains in asthma and COPD treatment.
