Salbutamol (INN) or albuterol (USAN) is a short-acting β2-adrenergic receptor agonist used for the relief of bronchospasm in conditions such as asthma and chronic obstructive pulmonary disease.

2008-03-15 00:04:31 補充：
Salbutamol 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).

2008-03-15 00:04:59 補充：
In these forms of delivery, the maximal effect of Salbutamol can take place within five to twenty minutes of dosing, though some relief is immediately seen.

2008-03-15 00:05:07 補充：
Salbutamol 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.

2008-03-15 00:06:03 補充：
Salbutamol is specifically indicated in the following conditions:

1.acute asthma
2.symptom relief during maintenance therapy of asthma and other conditions with reversible 3.airways obstruction (including COPD)

2008-03-15 00:06:12 補充：
4.protection against exercise-induced asthma
5.hyperkalaemia, especially in patients with renal failure
6.can be aerosolized with a nebulizer for patients with cystic fibrosis, along with ipratropium bromide and pulmozyme.

As a β2-agonist, salbutamol also finds use in obstetrics. Intravenous salbutamol can be used as a tocolytic to relax the uterine smooth muscle to delay premature labour.

2008-03-15 00:06:42 補充：
Whilst preferred over agents such as atosiban and ritodrine, its role has largely been replaced by the calcium-channel blocker nifedipine which is more effective, better tolerated and orally administered

2008-03-15 00:07:06 補充：
As with other β2-adrenergic receptor agonists, salbutamol binds to β2-adrenergic receptors with a higher affinity than β1-receptors. In the airway, activation of β2-receptors results in relaxation of bronchial smooth muscle resulting in a widening of the airway (bronchodilation).

2008-03-15 00:07:22 補充：
Inhaled salbutamol sulfate has a rapid onset of action, providing relief within five to fifteen minutes of administration.

In tocolysis, the activation of β2-receptors results in relaxation of uterine smooth muscle, thus delaying labour.
