bronchodilators
Because       beta(2)-adrenoceptor agonists are the most widely used bronchodilators in asthma,       we investigated the effects of the beta(2)-adrenoceptor agonist fenoterol on       NK(2) receptor messenger RNA (mRNA) and receptor density as well as the       functional responses of bovine tracheal smooth muscle to the NK(2) receptor       agonist [beta-Ala(8)]-NKA(4-10) in vitro, using Northern blot analysis, receptor        binding, and organ bath studies.
