During an acute asthma attack, which medication would most effectively reduce symptoms?

• A. Albuterol via jet nebulizer
• B. Cromolyn via MDI
• C. Montelukast orally
• D. Budesonide via DPI

Answer: (A)

In an acute asthma attack, the immediate goal is to reverse bronchoconstriction and open the airways quickly. Short-acting beta-2 agonists like albuterol provide rapid bronchodilation by stimulating beta-2 receptors on airway smooth muscle, which raises cAMP inside the cells and causes the muscles to relax. Delivering albuterol as a jet nebulizer ensures the medicine reaches the airways efficiently and can be used even when breathing is labored or when the patient has difficulty coordinating an inhaler. This provides fast symptom relief. The other options don’t offer that quick relief. Cromolyn stabilizes mast cells and mainly helps prevent mediator release; it has little effect during an active attack. Montelukast blocks leukotriene receptors but takes days to weeks to work, so it’s for long-term control rather than immediate relief. Budesonide is an inhaled corticosteroid that reduces inflammation, but it doesn’t work rapidly enough to help during an acute episode and is used for chronic control.
