What type of medication is frequently used for acute asthma attacks?

Short-acting beta-agonists are the preferred medication for managing acute asthma attacks. These medications work by quickly relaxing the muscles around the airways, leading to rapid bronchodilation, which helps to alleviate symptoms such as wheezing and shortness of breath. Often referred to as "rescue inhalers" or "relievers," these agents are designed for immediate action and typically provide relief within minutes, making them essential for emergency situations.

In contrast, long-acting beta-agonists are primarily used for maintenance therapy to prevent asthma symptoms and are not intended for quick relief during an acute exacerbation. Anticholinergics can also help with bronchodilation but are generally used more in chronic cases rather than acute episodes. Inhaled corticosteroids are effective in reducing inflammation in the airways and are commonly used for long-term control but do not act quickly enough to be effective during an acute attack. Thus, short-acting beta-agonists are the optimal choice for immediate relief in acute asthma situations.
