Final answer:
Effective therapy for moderate asthma with salmeterol involves a combination of long-term control and short-term reliever medication, such as Advair.
Step-by-step explanation:
Effective therapy for moderate asthma with salmeterol is typically a combination of long-term control medication and short-term reliever medication. Salmeterol is a long-acting beta-agonist bronchodilator that helps to prevent asthma symptoms and control inflammation in the airways. It is usually prescribed in combination with an inhaled corticosteroid, such as fluticasone, to provide both long-term control and quick relief of symptoms. For example, a commonly prescribed combination medication is Advair, which contains salmeterol and fluticasone.
