Bedoradrine (also known as KUR-1246 or MN-221), an ultra selective beta 2-adrenoceptor agonist, that participated in phase II clinical trials as an adjunct to standard therapy in the management of patients with acute exacerbation of asthma who did not respond to standard therapy. In addition, the drug was involved in trials for the treatment of preterm labor in obstetrical practice. Bedoradrine is also was studied in phase I of clinical trials for its use for treating chronic obstructive pulmonary disease, however, the efficacy for this disease was uncertain.
