Bronchodilators are either short-acting or long-acting. Short-acting medications provide quick or "rescue" relief from acute bronchoconstriction. Long-acting bronchodilators help to control and prevent symptoms. The three types of prescription bronchodilating drugs are beta-2 adrenergic agonists (short- and long-acting), anticholinergics (short ...
Bronchodilators are considered an important treatment regime for chronic obstructive pulmonary disease (COPD) and are usually used in combination with short acting medications and long acting medications in a combined inhaler. [1] [2]
Short-acting β 2-agonists are used to treat exercise-induced asthma, [7] and for asthma patients to get a quick relief of symptoms. They are taken 10–15 minutes before exercise. The bronchodilation begins few minutes after inhalation of short-acting β 2-agonists and lasts from 4 to 8 hours.
Inhaled short-acting β2-adrenergic agonists, such as terbutaline and salbutamol, are the first-line drugs indicated for asthma exacerbation for all patients to provide rapid bronchodilating effects. [1] [2] Short-acting β2-adrenergic agonists can be delivered by different devices, for example, nebulizers and metered-dose inhalers. [2]
Umeclidinium bromide is a long-acting muscarinic antagonist. [14] This combination was approved by the FDA on December 18, 2013 [15] for the long-term maintenance treatment of COPD. On March 28, 2014, it was approved in European countries [16] and in Russia [17] under the same trade name.
Formoterol, also known as eformoterol, is a long-acting β 2 agonist (LABA) used as a bronchodilator in the management of asthma and chronic obstructive pulmonary disease (COPD). Formoterol has an extended duration of action (up to 12 h) compared to short-acting β 2 agonists such as salbutamol (albuterol), which are effective for 4 h to 6 h.

These medications include short-acting beta agonists (SABAs) such as albuterol which typically last 4–6 hours, and long-acting beta agonists (LABAs) such as salmeterol which lasts 12 hours. [5] For example, during an acute asthma exacerbation where airway smooth muscle is constricted, inhalation of SABAs provide rapid relief of symptoms ...
