Bronchodilators are medicines that help open the airways (bronchi) of your lungs. This lets more air flow through them. These medicines work by relaxing the smooth muscles that line the airways. This makes the airways open wider. And it allows air to leave the lungs. These medicines are used to ease breathing problems caused by lung diseases. These include asthma, emphysema, and chronic bronchitis.
There are two main types:
-
Short-acting bronchodilators. These ease symptoms quickly.
-
Long-acting bronchodilators. These control symptoms over time. They are not used for quick relief.
These medicines are used differently. Make sure you know if you have a short-acting or a long-acting medicine. Your provider may prescribe one or both types.
