Which medication is commonly used as a rescue inhaler for COPD patients?

Albuterol is commonly used as a rescue inhaler for patients with Chronic Obstructive Pulmonary Disease (COPD). This medication is a short-acting beta-agonist (SABA) that works by relaxing the muscles in the airways, leading to dilation and improved airflow. Patients often rely on albuterol inhalers to quickly relieve symptoms of bronchoconstriction, such as wheezing and shortness of breath, which can occur during COPD exacerbations or episodes of deterioration in their condition.

While other medications are important in the management of COPD, they serve different roles. Atrovent, for example, is an anticholinergic medication that is more typically used for maintenance therapy rather than for immediate relief. Prednisone is a corticosteroid that may be used for managing acute inflammation but is not intended for immediate symptom relief. Oxygen therapy, while crucial for patients with severe COPD experiencing hypoxemia, is not considered a medication but rather a supportive treatment. Thus, albuterol is specifically designed for quick access to relief, making it the preferred choice as a rescue inhaler.
