COPD Inhalers: The Sprinter and The Marathon Runner

Key Information

• How Inhalers Work: Inhalers are the main treatment for COPD. They relax the muscles around your airways, helping them open up so air can move more freely.
• Why This Matters: Understanding how and when to use your inhalers is key to controlling your symptoms and improving your day-to-day breathing.

The Two Types of Inhalers

To understand when to use each inhaler, think of them as a “Sprinter” and a “Marathon Runner.”

• 1. The Sprinter (Short-Acting Reliever)
  Colour: Often blue.
  When to use: When you suddenly feel breathless.
  How it works: Acts quickly (within minutes) to give rapid relief.
  Duration: Lasts for a few hours.
• 2. The Marathon Runner (Long-Acting Maintenance)
  When to use: Taken every day as prescribed (usually once or twice daily).
  How it works: Works slowly and steadily in the background.
  Duration: Keeps airways open for 12–24 hours.
  Role: Prevents breathlessness and keeps symptoms under control long-term.

Using your inhaler correctly is essential. Even the best medicine will not work properly if it does not reach deep into your lungs.
