Long-acting beta-agonists in the management of chronic obstructive pulmonary disease: current and future agents

β2-agonists are widely used in the management of COPD, either alone or in combination with other bronchodilators, corticosteroids, or both. Short-acting β2-agonists (SABAs) were the first agents of the class to become available for the treatment of COPD. LABAs with a 12-hour duration of action were subsequently introduced in the late 1990s, following positive experience in asthma, providing improvements in bronchodilator efficacy and patient outcomes compared with SABAs which have a duration of action of only 4-6 hours.

For patients with Stage II (moderate) or more severe COPD, regular treatment with a twice-daily LABA such as formoterol or salmeterol, or a long-acting muscarinic…

Long-acting beta2-agonists for people with COPD

Moderate-quality evidence from 26 studies showed that inhaled long-acting beta2-agonists are effective over the medium and long term for patients with moderate to severe COPD. Their use is associated with improved quality of life and reduced exacerbations, including those requiring hospitalisation. Overall, findings showed that inhaled LABAs did not significantly reduce mortality or serious adverse events.

Adrenergic Bronchodilators: Overview and Practice Questions

They work by stimulating alpha, beta-1, and beta-2 receptors. Alpha-receptor stimulation causes vasoconstriction, which could result in increased blood pressure.

Bronchodilators in COPD: Impact of β-agonists and anticholinergics on severe exacerbations and mortality

The main therapeutic options for the management of COPD are inhaled corticosteroids and bronchodilators. Inhaled corticosteroids significantly reduce inflammatory cells in the lungs, as well as systemic inflammatory markers such as C-reactive protein, compared with placebo. However, there is some evidence that corticosteroids have no antiinflammatory effects in COPD patients who are still smoking.

Concomitant Use of Beta-Blockers, Beta-Agonists in COPD With CV Risk

Patients with chronic obstructive pulmonary disease (COPD) and heightened cardiovascular (CV) risk continued to receive respiratory benefit without an increased CV risk from long-acting beta-agonist therapy, irrespective of baseline beta-blocker therapy, according to a study published in the Annals of the American Thoracic Society.

Impact of multiple-dose versus single-dose inhaler devices on COPD patients’ persistence with long-acting β2-agonists: a dispensing database analysis

This study showed no significant impact of inhaler device on COPD patients’ persistence with LABAs: persistence of patients initiating multiple-dose inhalers was comparable to patients initiating single-dose inhalers.

Overuse of short-acting beta-agonist bronchodilators in COPD during periods of clinical stability

We found that nearly half of our sample of participants with COPD overused their SABA inhaler at least once during three months of observation, with 19% overusing their SABA more than half of the days. The overusers had evidence of more severe COPD than non-overusers, and were more likely to be using home oxygen therapy and to have increased dyspnea. Despite this, more than 25% of participants were not prescribed GOLD-guideline concordant COPD medications.

β2-selective adrenergic receptor agonists: Overview

Previously, descriptions of pharmacological effects associated with "non-selective" β-adrenergic receptor agonists used to manage pulmonary diseases such as asthma or COPD necessarily include unwanted side effects often due to β1 adrenergic receptor activation. Specifically, myocardial effects are particularly emphasized.
