For children aged 5-11, which maintenance and reliever strategy is commonly used?

• A. Low Dose ICS
• B. Low Dose ICS/Formoterol + PRN ICS/Formoterol
• C. High Dose ICS/Formoterol
• D. Oral corticosteroids

Answer: (B)

Using a single inhaler that combines a low dose of inhaled corticosteroid with formoterol as both daily maintenance and as-needed relief is commonly used in children aged 5–11. Formoterol acts quickly to relieve symptoms, while the corticosteroid continuously reduces airway inflammation. This maintenance-and-reliever strategy (often called MART or SMART) helps prevent exacerbations and improves overall control by delivering anti-inflammatory treatment during periods of symptoms, not just during daily maintenance.

Choosing only a low-dose ICS provides maintenance but no rapid-relief option. A high-dose ICS/formoterol bumps the steroid exposure without clear added benefit for most children in this age group and increases potential side effects. Oral corticosteroids are systemic and reserved for severe cases or acute exacerbations, not regular maintenance in this population.
