Which type of medication is commonly used as a rescue treatment during an asthma attack?

Short-acting beta-agonists are commonly used as rescue treatments during an asthma attack because they provide rapid relief of bronchoconstriction. These medications, such as albuterol, work by quickly relaxing the muscles around the airways, allowing for increased airflow and immediate symptom relief. Their action can typically be felt within minutes, making them ideal for acute situations where fast relief is necessary.

In contrast, long-acting beta-agonists are used for maintenance therapy and are not designed for immediate relief. Inhaled corticosteroids are primarily intended for long-term control and prevention of asthma symptoms rather than treating acute episodes. Leukotriene modifiers are also used for long-term management but do not provide the instant relief needed during an attack.
