Which of the following is given in the maintenance of severe persistent asthma?: (A) Oral Steroid, (B) Leukotriene agonist, (C) Ipratropium bromide, (D) Long-acting beta 2 agonist
Answer is D. LABAs improve asthma control and reduce exacerbations when added to ICS, which allows asthma to be controlled at lower doses of coicosteroids. LABAs should not be given in the absence of ICS therapy as they do not control the underlying inflammation.
