What's a Bronchodilator?
A person with asthma may need to take a medicine called a bronchodilator. This type of medicine dilates (a fancy word for opens) the airways, or bronchial tubes. This usually means using an inhaler, which is a plastic tube that holds a container of medicine. You may have seen a friend or someone in school using an inhaler, which is held up to the mouth and breathed into the lungs.
