Advair Diskus is a drug manufactured to cope with diseases which attack bronchi and lungs. Medics prescribe it for people with COPD, pant, wheeze, dyspnea, pulmonary emphysema, and chronic bronchitis. It consists of two main components: a corticosteroid (Fluticasone) and a long-acting beta agonist (Salmeterol). The first component reduces the irritation and the swelling of lungs and bronchi. The second component makes the breathing easier. Doctors prescribe the drug for patients who need a combination treatment when one medication doesn’t work. The medicine is a part of a long-term medication as it isn’t effective in case of sudden asthma attacks.
