What is a bronchodilator?

A bronchodilator opens the airways by relaxing the smooth muscle around them, making it easier to breathe when the air passages become narrowed during a flare-up. It’s commonly used as a rescue inhaler for asthma and other airway conditions, with albuterol being a typical active ingredient that acts quickly to relieve symptoms. The other options describe drugs for different purposes: stopping bleeding, calming nerves, or treating infections, none of which affect airway dilation.
