Serevent Salmeterol inhalation aerosol What does salmeterol inhalation aerosol do?SALMETEROL (Serevent(R)) is a slow-acting bronchodilator, a medicine that opens up air passages and makes breathing easier. Salmeterol is for regular use to help prevent asthma attacks and is not for use in an acute asthma attack. It can also be used to prevent exercise-induced bronchospasm, at least 30 to 60 minutes before exercise is started. You must have a quick-acting bronchodilator (such as albuterol) readily available for use in an asthma attack.
