Final answer:
The generic name of Advair is fluticasone/salmeterol (option a). It is used for the control and prevention of symptoms related to asthma and COPD by reducing inflammation and relaxing airway muscles.
Step-by-step explanation:
The generic name of the drug Advair is fluticasone/salmeterol. This combination medication is used to control and prevent symptoms (such as wheezing and shortness of breath) caused by asthma or ongoing lung disease (chronic obstructive pulmonary disease-COPD, which includes chronic bronchitis and emphysema). Fluticasone is a corticosteroid that decreases inflammation in the lungs, while salmeterol is a long-acting beta agonist that relaxes muscles in the airways to improve breathing.
It is important to note that Advair is not a rescue drug and should not be used to relieve sudden asthma attacks; for sudden breathing problems, an inhaled, short-acting bronchodilator (such as albuterol) is prescribed.
