Bioactivity	Levalbuterol ((R)-Albuterol) hydrochloride is a short-acting β2-adrenergic receptor agonist and the active (R)-enantiomer of Salbutamol. Levalbuterol hydrochloride is a more potent bronchodilator than Salbutamol and has the potential for the treatment of COPD[1].
Invitro	Levalbuterol (10 μM; 24 hours) hydrochloride induces 11β-HSD1 mRNA expression, however, it does not influence 11β-HSD2expression in airway epithelial cells[1].Levalbuterol (10 μM; 24 hours) hydrochloride significantly reduces both LPS- and TNF-α-induced NF-κB activity while increasing GRE activation in an 11β-HSD1 dependent manner in a transformed mouse airway epithelial cell line[1].
