What is "levosalbutamol"

n. A bronchodilator used to treat asthma and COPD.

Levosalbutamol or levalbuterol is a short-acting β adrenergic receptor agonist used in the treatment of asthma and chronic obstructive pulmonary disease (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 some countries in generic formulations from pharmaceutical companies including Cipla, Teva, and Dey, among others.

Evidence does not show that levosalbutamol works better than salbutamol, thus there may not be sufficient justification for prescribing it.
