Also Known As: Levalbuterol, Xopenex, Levosalbutamol
Levosalbutamol (INN) or levalbuterol (USAN), trade name Xopenex, is the R-enantiomer of the short-acting Î²2-adrenergic receptor agonist salbutamol. It is marketed by Cipla as Levolin, & by axa named Axazest.
As a bronchodilator, it is used to treat asthma and Chronic obstructive pulmonary disease (COPD). In general, levosalbutamol has similar pharmacokinetic and pharmacodynamic properties to salbutamol; however, its manufacturer, Sepracor, has implied (although not directly claimed) that the presence of only the R-enantiomer produces fewer side effects.
