title: Ultra long-acting beta 2-agonists in development for asthma and chronic obstructive pulmonary disease.
abstract: After the discovery of formoterol and salmeterol, new candidates for long-acting beta2-adrenoceptor agonists (LABAs) have emerged from various companies. In particular, once-daily beta2-adrenoceptor agonists such as arformoterol, carmoterol, indacaterol, GSK-159797, GSK-597901, 159802, 642444 and 678007 are under development for the treatment of asthma and chronic obstructive pulmonary disease. The majority of these compounds are (R,R)-isomers in order to control desensitisation and accumulation. Several options for combination products are currently being evaluated in parallel with the development of these ultra LABAs. Once-daily dosing of an ultra LABA would be a significant convenience and probably a compliance-enhancing advantage leading to improved overall clinical outcomes in patients with asthma and chronic obstructive pulmonary disease. The only limits set for the development of a LABA with a new product profile are medical needs and marketing opportunities.
