Quizplus · Accepted Answer

Salmeterol and formoterol are two long-acting beta-2 drugs with increased beta-2 receptor selectivity. Administration is by inhalation and each provides a duration of action of approximately 12 hours. While these two drugs are "reliever drugs," they are not considered "rescue drugs" because the onset of action usually requires 10 to 20 minutes.
