Why do kids with asthma carrying around an inhaler? What exactly is in there?

A drug called albuterol is what’s inside an inhaler. What asthma does is make the small tubes in your lungs called bronchioles contract, making it hard for oxygen to get through your lungs to alveoli.

That’s why it’s very tough for asthmatics to breathe during an asthma attack. What the albuterol does is act as a muscle relaxant. As the albuterol travels through the bronchioles, it relaxes the bronchioles tubes, which are made of smooth muscle, allowing for air to get through.
