Brand Names

Advair, Airduo, Airduo Respiclick, Serevent, Serevent Diskus, Wixela

Generic Name

Salmeterol

DrugBank Accession Number

DB00938

Background

Salmeterol is a long-acting beta-2 adrenergic receptor agonist drug that is currently prescribed for the treatment of asthma and chronic obstructive pulmonary disease COPD.^8,9,10,11,12 It has a longer duration of action than the short-acting beta-2 adrenergic receptor agonist, salbutamol.⁵ Salmeterol was first described in the literature in 1988.⁶ Salmeterol's structure is similar to salbutamol's with an aralkyloxy-alkyl substitution on the amine.¹

Salmeterol was granted FDA approval on 4 February 1994.⁷

Pharmacology

Indication

Salmeterol is indicated in the treatment of asthma with an inhaled corticosteroid, prevention of exercise induced bronchospasm, and the maintenance of airflow obstruction and prevention of exacerbations of chronic obstructive pulmonary disease.^8,9,10,11,12

Pharmacodynamics

Salmeterol is a long acting beta-2 adrenergic receptor agonist that binds to both the active and exo sites of the beta-2 adrenergic receptor.¹ Salmeterol has a longer duration of action than other beta-2 agonists like salbutamol.⁵ Patients should be counselled regarding the risks of long acting beta agonist (LABA) monotherapy, hypokalemia, hypoglycemia, and not to take this drug with another LABA.^8,9,10,11,12

Mechanism of action

Beta-2 adrenoceptor stimulation causes relaxation of bronchial smooth muscle, bronchodilation, and increased airflow.¹

Salmeterol is hypothesized to bind to 2 sites on the beta-2 adrenoceptor.¹ The saligenin moiety binds to the active site of the beta-2 adrenoceptor.¹ The hydrophilic tail of salmeterol binds to leucine residues in the exo-site of the beta-2 adrenoceptor almost irreversibly, allowing salmeterol to persist in the active site, which is responsible for it's long duration of action.^1,3

Another hypothesis is that the lipophilic drug diffuses into lipid bilayer of smooth muscle cells and provides a depot of drug to the cells over a longer period of time.¹

UBeta-1 adrenergic receptor	inverse agonist	Humans
UBeta-3 adrenergic receptor	inverse agonist	Humans

Absorption

In asthmatic patients, a 50µg dose of inhaled salmeterol powder reaches a C_max of 47.897pg/mL, with a T_max of 0.240h, and an AUC of 156.041pg/mL/h.⁵

Volume of distribution

In asthmatic patients, the volume of distribution of the central compartment is 177L and the volume of distribution of the peripheral compartment is 3160L.⁵

Protein binding

Salmeterol is 96%⁸ protein bound in plasma to albumin and alpha-1-acid glycoprotein.¹

Metabolism

Salmeterol is predominantly metabolized by CYP3A4 to alpha-hydroxysalmeterol,¹ and minorly by an unknown mechanism to an O-dealkylated metabolite.²

  • alpha-hydroxysalmeterol
  • Salmeterol O-dealkylated Metabolite

Route of elimination

Salmeterol is 57.4% eliminated in the feces⁹ and 23% in the urine.¹ Less than 5% of a dose is eliminated in the urine as unchanged salmeterol.¹

Half-life

The half life of salmeterol is 5.5h.¹

Clearance

The average clearance of salmeterol in a group of asthmatic patients was 392L/h.⁵ Further data regarding the clearance of salmeterol is not readily available.^8,9,10,11,12

Toxicity

Patients experiencing an overdose have presented with metabolic acidosis, hyperlactatemia, anxiety, palpitations, chest pain, sinus tachycardia, ST depression, hypokalemia, hypophosphatemia.⁴ Though patients may also present with seizures, angina, hypertension or hypotension, arrhythmia, headache, tremor, muscle cramps, dry mouth, nausea, dizziness, fatigue, malaise, insomnia, and hyperglycemia.⁹ Patients should be given symptomatic and supportive treatment which may include intravenous fluids, potassium supplementation, a cardioselective beta-blocker, and cardiac monitoring.^4,9
