Carmoterol (INN),[1] also known as TA-2005 and CHF-4226, is a non-catechol[2] experimental ultra-long-acting β adrenoreceptor agonist (ultra-LABA)[2][3] that was in clinical trials before 2010 when it has been withdrawn from further development based on evidence that the compound does not possess a competitive profile.[4]

Preliminary studies indicated duration of its effect exceeding 24 hours after inhalation of 3 μg.[2] The pharmacologic profile of this medication included the fact its potency in isolated guinea pig trachea is greater than that of formoterol and salmeterol. It is over 100 times more selective for bronchial muscle than myocardial tissue.[5]
