Summary

Long-acting beta(2)-agonists offer convenient dosing and improve symptoms for chronic obstructive pulmonary disease (COPD) patients. These bronchodilators are considered acceptable first-line treatments for COPD management.

Area of Science:

  • Pulmonary Medicine
  • Pharmacology

Background:

  • Chronic obstructive pulmonary disease (COPD) incidence and mortality have risen globally.
  • COPD is a progressive, irreversible condition marked by chronic cough, dyspnea, and wheezing.
  • No medication, except oxygen, has proven to decrease COPD mortality.

Purpose of the Study:

  • To review the pathogenesis of COPD.
  • To examine the benefits, formulations, costs, pharmacokinetics, and clinical studies of long-acting beta(2)-agonists (LABAs).

Main Methods:

  • A comprehensive MEDLINE search was conducted from July 1966 to October 2002.
  • Articles focusing on COPD and long-acting beta(2)-agonists were selected for review.

Main Results:

  • Long-acting beta(2)-agonists (formoterol, salmeterol) offer twice-daily dosing convenience over short-acting bronchodilators.

Related Experiment Videos

  • Both formoterol and salmeterol demonstrate acceptable safety profiles at recommended doses.
  • LABAs have shown benefits in improving COPD symptoms, spirometry, exacerbations, and quality of life compared to ipratropium and theophylline.
  • Conclusions:

    • Long-acting beta(2)-agonists are recommended as acceptable first-line agents for COPD management.
    • Further clinical outcome studies directly comparing formoterol and salmeterol are warranted.
