Aka: Long-acting Beta Agonist, Long-Acting Beta-2 Agonist, Long-Acting Inhaled Bronchodilator, Salmeterol, Serevent, Formoterol, Foradil, Indacaterol, Arcapta, Advair, Symbicort, Breo Ellipta, Arformoterol, Brovana, Trelegy Ellipta

II. Indications

  1. Moderate Persistent Asthma
  2. Severe Persistent Asthma

III. Precautions

  1. Adverse outcomes in Asthma with Long-acting Beta Agonist (LABA)
    1. LABA use in Asthma was associated with increased Asthma deaths, increased intubations and hospitalizations
      1. McMahon (2011) Pediatrics 128(5): e1147-54 [PubMed]
    2. However FDA review of more recent studies found similar adverse outcomes with Inhaled Corticosteroids
      1. FDA removed LABA black box warning (see FDA communication link below)
  2. Risk of increased mortality and of more severe and life threatening Asthma Exacerbations
    1. Postulated to mask a patients awareness of severe Asthma Exacerbation
    2. FDA Black Box Warnings placed in 2003, but removed in 2017 (based on newer data as above)
      1. https://www.fda.gov/Drugs/DrugSafety/ucm589587.htm
  3. Not a substitute for Inhaled Corticosteroids
    1. Steroids are key management of persistent Asthma
    2. Long-acting Beta Agonists are in addition to Inhaled Corticosteroids
    3. Lazarus (2001) JAMA 285:2583-93 [PubMed]
  4. Do NOT exceed dosing schedule (e.g. Serevent bid)
    1. Use a short acting Beta agonist for rescue use
  5. Tolerance over time to Protective effect
    1. Effect diminishes over one month of use
    2. Reference
      1. Simons (1997) Pediatrics 99:655-9 [PubMed]

Ontology: formoterol (C0060657)

Definition (NCI) A long-acting beta-adrenergic receptor agonist with bronchodilator activity. Formoterol selectively binds to beta-2 adrenergic receptors in bronchial smooth muscle, thereby activating intracellular adenyl cyclase, an enzyme that catalyzes the conversion of adenosine triphosphate (ATP) to cyclic-3',5'-adenosine monophosphate (cAMP). Increased cAMP levels cause relaxation of bronchial smooth muscle, relieve bronchospasms, improve mucociliary clearance and reduce mediator substance release from inflammatory cells, especially from mast cells.

Ontology: salmeterol (C0073992)

Definition (NCI) A highly selective, long-acting beta-2 adrenergic agonist with bronchodilatory activity. Salmeterol's benzene moiety resembles the structure of catecholamines, and occupies the active site of beta-2 adrenergic receptor, while the long, lipophilic side chain of salmeterol, binds to the so called 'exosite' near the beta-2 adrenergic receptors. The binding at the exosite allows the active portion of the molecule to remain at the receptor site and continually engage and disengage with the receptor, therefore providing a long duration of action. This agent stimulates intracellular adenyl cyclase to catalyze the conversion of adenosine triphosphate to cyclic-3',5'-adenosine monophosphate (cAMP). Increased cAMP levels result in relaxation of bronchiolar smooth muscle, bronchodilation and increased bronchial airflow.
