134. SYMPATHOMIMETIC AMINES AND RELATED DRUGS ACTING ON THE BRONCHI 



Drugs are listed to illustrate, as far as possible, the relationship between chemical structure and pharmacological 

 action. Inclusion of trade names is for informative purposes only and in no way implies endorsement by The National 

 Academy of Sciences-The National Research Council. For all "effects" included in this table, there is reasonable 

 evidence the drug in fact acted on the bronchial musculature. Where there was evidence that an effect was medi- 

 ated by the respiratory center or adrenal glands, it was excluded. Drug actions influencing only anaphylactic or 

 asthmatic bronchospasm, or other pathological states of the bronchi, were also excluded. Concentrations of drugs 

 are given in mjig/ml for local actions on isolated preparations, and doses in (ig/kg for drugs administered 

 systemically. Parentheses in Columns D and F indicate action is slight, irregular, or doubtful, and the original 

 literature should be consulted. A = active, but action complex (original literature should be consulted); C = 

 constricts; D = dilates: I = inactive.
