Question: Do inhaled corticosteroids prevent the development of tolerance to the bronchoprotective effect of salmeterol?
Answer: Tolerance to the acute bronchoprotective effect of salmeterol was significant after the first two doses and persisted after the seventh dose. Tolerance to the acute bronchoprotective effect of salbutamol was also significant after regular use of salmeterol for seven doses. These effects, in subjects using inhaled corticosteroids regularly, were similar to the those previously seen in patients with mild asthma using as-required beta 2-agonists only, indicating that tolerance is not prevented by use of inhaled corticosteroids.
