<unk>  (INN) or albuterol (USAN) is a short-acting β2-adrenergic receptor agonist used for the relief of bronchospasm in conditions such as asthma and COPD.<unk>  sulphate is usually given by the inhaled route for direct effect on bronchial smooth muscle. This is usually achieved through a metered dose inhaler (MDI), nebuliser or other proprietary delivery devices (e.g. Rotahaler or Autohaler). In these forms of delivery, the maximal effect of<unk>  can take place within 5 to 20 minutes of dosing, though some relief is immediately seen.<unk>  can also be given orally or intravenously. However, some asthmatics may not respond to these medications as they will not have the required DNA base sequence in a specific gene.<unk>  became available in the United Kingdom in 1969 and in the United States in 1980 under the trade name Ventolin.
