What is the role of rescue inhalers in asthma management?

Rescue inhalers are specifically designed to provide quick relief from acute asthma symptoms during an asthma attack. These inhalers typically contain short-acting beta-agonists (SABAs), which work by rapidly relaxing the muscles around the airways, thereby allowing them to open up and improve airflow. This immediate response helps alleviate symptoms such as wheezing, coughing, and shortness of breath, making them essential for individuals needing urgent care during an asthma episode.

While preventive treatments and long-term control options exist to manage asthma by reducing inflammation or preventing attacks, these are not the primary function of rescue inhalers. Rescue inhalers are distinct from therapies that modify the underlying disease process or provide ongoing control. Instead, their role is strictly to act as a rapid intervention when symptoms suddenly worsen, ensuring that individuals can quickly regain control of their breathing.
