Bronchodilators - Short-acting Beta-2 Agonists (SABA)

Drug names:

Salbutamol - e.g. Ventolin.
Terbutaline - e.g. Bricanyl.

These drugs act quickly within 5-15 minutes and are effective for 3-5 hours. They are given for the immediate relief of breathlessness.

They come in inhaler form and also can be nebulised.

Precautions:

Some patients develop an over-reliance on inhaler use due to prompt relief of symptoms and impression that the inhaler is ‘helping’.
Symptoms are only relieved. Bronchodilators do not contribute to control of underlying disease and may mask severity of disease.
Increasing need for bronchodilator medication may suggest declining control of condition.
Patients may be using short acting bronchodilators for relief of symptoms that are unrelated to their respiratory condition and may require medical or specialist review.
