Salbutamol (INN) or albuterol (USAN) is a temporary-acting β 2 -adrenergic receptor agonist used for the relief of bronchospasm in conditions such as asthma and continuing obstructive pulmonary disease. It is marketed by GlaxoSmithKline as Ventolin , Aerolin or Ventorlin depending on the retail; by Cipla as Asthalin ; by Schering-Plough as Proventil and by Teva as ProAir . Generic names are currently not accessible in the U.S. because of a federal ban on the use of CFCs.
Salbutamol sulfate is usually given by the inhaled way for direct effect on bronchial smooth muscle. This is usually achieved utterly a metered dose inhaler (MDI), nebuliser or other proprietary delivery devices (e.g. Rotahaler or Autohaler). In these forms of transportation, the maximal effect of Salbutamol can take place within five to twenty minutes of dosing, albeit some relief is immediately seen. Salbutamol can also be given orally as an inhalant or intravenously.
Salbutamol became at in the United Kingdom in 1969 and in the United States in 1980 under the trade celebrity Ventolin.
Clinical use
Salbutamol is specifically indicated in the following conditions:
- Acute asthma
- Earmark relief during maintenance therapy of asthma and other conditions with reversible airways hindrance (including COPD and bronchitis)
- Protection against exercise-induced asthma
- Can produce Hypokalemia, especially in patients with renal failure
- Can be aerosolized with a nebulizer for patients with cystic fibrosis, along with ipratropium bromide and pulmozyme.
As a β 2 -agonist, salbutamol also finds use in obstetrics. Intravenous salbutamol can be against as a tocolytic to relax the uterine smooth muscle to delay premature labour. While preferred onto agents such as atosiban and ritodrine, its role has largely been replaced by the calcium-canal blocker nifedipine which is more effective, better tolerated and orally administered.
In an crisis, EMS providers consider the administration of Albuterol when they see Active Wheezing, bronchospasm and a nearby diagnosis of Asthma. The drug is most often administered through a nebulizer with 8 liters of unmitigated oxygen. A normal dose is aprox. 2.5mg in 3 mL of respiratory saline.

Ban of CFC-containing salbutamol inhalers
The U.S. Scoff & Drug Administration in April 2005 mandated that all (including salbutamol) inhalers containing chlorofluorocarbons (CFCs) transfer be prohibited in the United States as of 12/31/2008. CFC inhalers had previously been given "material use" status, exempting it from a CFC-production ban, however in accordance with the Montreal Conduct they will be phased out; in many other countries patients have been transitioned to non-CFC based inhalers using hydrofluoroalkane (HFA) propellant. Pharmaceutical manufacturers are expected to bring forward adequate supplies of alternative (HFA) inhalers by 2009.
One drawback of this transition to HFA inhalers is that due to conspicuous restrictions all of the HFA salbutamol inhalers are "brand-name" (ProAir, Proventil, and Ventolin). They bring in approximately $20 more per inhaler than existing generic CFC salbutamol inhalers. Because the HFA propellants bear different chemical and physical properties, inhaler formulations with the new propellants had to be developed. In condition to protect the huge investment in time and money, these new formulations were patented. An vigour consortium was formed to spread the costs of the FDA safety studies to get propellants such as 134a and 227 approved.
Generic HFA salbutamol inhalers are not expected on the Unified States market until 2012 due to existing patents.
Another drawback that is coming to headlamp now as the use of HFA/HFA+ethanol inhalers is expanding seems to be a far higher intolerance of the new inhalers compared to CFC propellant in patients. Registered complaints run the range from "doesn't seem to work as well" all the way to serious anaphylaxis in response to using an HFA or HFA+ethanol inhaler.
Salbutamol is largely used, and accounts for anywhere from 78% of all bronchodilator prescriptions in 2005 to 85% in 2008. Setting aside how, patients in the United States who cannot tolerate the HFA salbutamol inhalers will not would rather a single salbutamol alternative available to them domestically after December 31, 2008. The FDA did not approve any alternatives to HFA and there are few measure inhaled lung medications in the United States that come in Dry Powder Inhaler (DPI) versions. Noticeably missing is salbutamol in DPI manner in the United States, although it is available in most of the rest of the world in salbutamol DPIs.
Victuals and bodybuilding use
Salbutamol is taken by some as an alternative to Clenbuterol for purposes of fat burning.
