摘要: Short-acting β2-agonists provide greater protection against bronchoconstriction induced by adenosine 5 ′ -monophosphate (AMP) than direct-acting bronchoconstrictors such as histamine and methacholine. AMP is thought to cause via release of mediators from mast cells, which suggests that these drugs stabilize cells in vivo. This vivo property has not yet been demonstrated for long-acting β2-agonists. We undertook a double-blind, randomized, placebo-controlled, cross-over study investigate the effects single dose formoterol inhaled Turbuhaler (12 μ g) albuterol (200 on airway responsiveness 16 subjects with mild atopic asthma. Albuterol reduced 4.1 ± 0.5 3.5 0.4 doubling doses, respectively. In contrast, caused protective effect challenge, decreasing 6.0 0.8 4.2 ...
