Nevertheless, if the findings in the airways and skin can be extrapolated to humans, then one might speculate that normal subjects, who would not generally have access to inhaled steroids and/or [[beta].sub.2] adrenergics, might obtain relief from toxin-induced irritation with antihistamines.
This bronchoconstriction was significantly reduced (% inhibition) after pretreatment with the glucocorticosteroid budesonide (49%), the [[beta].sub.2] adrenergic agent albuterol (71%), the anticholinergic agent atropine (58%), and the histamine [H.sub.1]-antagonist diphenhydramine (47%).
Furthermore, the antigen-induced effects in this model can be ameliorated with the current armamentarium of clinically available asthma medications, including glucocorticosteroids, [[beta].sub.2] adrenergic agents, and leukotriene antagonists (Abraham 2000).
The constrictor effects of toxin were significantly reduced by pretreating the animals with the anticholinergic agent atropine (58% inhibition), the glucocorticosteroid budesonide (49% inhibition), the [[beta].sub.2] adrenergic agent albuterol (71% inhibition), and the histamine [H.sub.1]-antagonist diphenhydramine (47% inhibition).
Bronchiole smooth muscle is innervated by both sympathetic (beta-2 adrenergic) and parasympathetic (cholinergic) autonomic nerves, which exert opposite effects on the airways.
To prevent and counteract reversible episodes of bronchospasm, beta-2 adrenergic inhalers directly dilate the bronchioles.
These beta-2 adrenergic agonists exert a rapid bronchodilator effect and have a short duration.
