Umeclidinium bromide is primarily used as a long-acting muscarinic antagonist (LAMA) in the management of chronic obstructive pulmonary disease (COPD). It works by relaxing the muscles around the airways, making it easier to breathe. This medication is often prescribed as a maintenance treatment to help control symptoms like shortness of breath, wheezing, and coughing in patients with COPD. It is typically administered via inhalation using a dry powder inhaler, ensuring direct delivery to the lungs for effective action. Umeclidinium bromide is often used in combination with other bronchodilators or corticosteroids to enhance its therapeutic effects and improve lung function over time. Regular use helps reduce the frequency of COPD exacerbations and improves overall quality of life for patients.
