What is Xopenex?
Levosalbutamol (INN) or levalbuterol (USAN) is a short-acting β2-adrenergic receptor agonist used in the treatment of asthma and COPD. It is marketed under the brand name Xopenex, by Sunovion Pharmaceuticals Inc. The drug is the R-enantiomer of its prototype drug salbutamol (INN) or albuterol (USAN). It is available in generic formulations by pharmaceutical companies including Cipla, Teva, and Dey, among others.
There is no reason to use levosalbutamol over salbutamol.
