What role do inhalers play in asthma management?

Inhalers play a crucial role in asthma management by providing immediate relief of symptoms. When someone experiences an asthma attack or exacerbation, their airways constrict, making it difficult to breathe. Inhalers typically contain bronchodilators, which work by relaxing the muscles around the airways, leading to dilation and improved airflow. This helps to alleviate symptoms such as wheezing, coughing, and shortness of breath immediately after use.

The other options, while they may refer to different medications or effects, do not accurately reflect the primary function of inhalers in asthma management. Inhalers do not cure asthma permanently or act as a sedative; their purpose is to manage symptoms effectively and provide prompt relief during acute episodes.
