Which of the following is an aerosol therapy used for acute asthma treatment?

Short-acting beta agonists (SABAs) are recognized as the primary aerosol therapy for acute asthma treatment. These medications work by relaxing the muscles around the airways, leading to bronchodilation, which helps to quickly alleviate symptoms of asthma exacerbation such as wheezing and shortness of breath. SABAs are typically delivered via inhalers or nebulizers, allowing for rapid onset of action and targeted delivery to the lungs, making them ideal for immediate relief during an asthma attack.

The other options provided, while significant in asthma management, do not serve the same role for acute treatment. Oral corticosteroids are used to reduce inflammation over a longer term but do not provide immediate relief of bronchospasm. Long-acting beta agonists (LABAs) are intended for maintenance therapy and not suitable for acute rescue situations due to their delayed onset of action. Mast cell stabilizers work to prevent asthma symptoms by inhibiting the release of inflammatory mediators but do not offer the rapid bronchodilation necessary during an acute asthma attack.
