<unk>  mesylate (Tornalate) is a β2-adrenergic receptor agonist used for the relief of bronchospasm in conditions such as asthma and COPD. In these disorders there is a  narrowing of the airways (bronchi and their ramifications) that carry air to the lungs. Muscle spasm and inflammation within the bronchi get worse this narrowing.<unk>  relaxes the smooth muscles  present continuously around the bronchi and bronchioles facilitating the flow of air through them.<unk>  has a rapid onset of action (2–5 minutes) and may last up to 6–8 hours.
The drug, alone or in co-administration with theophylline, doesn't show cardiotoxic effect.
The USA Food and Drug Administration (FDA) approved<unk>  in December 1984. The drug was withdrawn from the market by Élan Pharmaceuticals in 2001.
