Chronic respiratory conditions, particularly asthma and Chronic Obstructive Pulmonary Disease (COPD), represent a significant global health burden. While both diseases are characterized by chronic airway inflammation and airflow limitation, they have distinct pathophysiological mechanisms, clinical presentations, and management strategies. For PharmD students, the ability to differentiate between these conditions and understand the nuances of their respective therapeutic approaches is crucial for providing effective patient care, optimizing medication regimens, and improving quality of life.
