What is the first-line rescue inhaler for acute bronchospasm in asthma?

• A. Albuterol
• B. Epinephrine
• C. Ipratropium
• D. Prednisone

Answer: (A)

Rapid relief in acute asthma comes from a fast-acting inhaled bronchodilator that activates beta-2 receptors in the airways. Albuterol fits this best because it is a short-acting beta-2 agonist delivered by inhalation, providing quick bronchodilation within minutes and lasting a few hours. This targeted action directly opens the narrowed airways during an attack, offering rapid relief of wheeze and dyspnea with minimal systemic effects. Epinephrine can be life-saving in severe allergic reactions or extremely unstable airway scenarios, but it acts systemically and is not the first-line rescue inhaler for a typical acute asthma attack. Ipratropium is a useful adjunct bronchodilator, especially in more severe exacerbations, but it is not the initial rescue therapy on its own. Prednisone is important for controlling inflammation, but its effects take hours to days, so it does not provide immediate relief during an acute episode.
