Pronunciation

al-BYOO-ter-ole

Classifications

Therapeutic Classification: bronchodilators

Pharmacologic Classification: adrenergics

Indications

REMS


Action

  • Binds to beta2-adrenergic receptors in airway smooth muscle, leading to activation of adenyl cyclase and increased levels of cyclic-3;, 5;-adenosine monophosphate (cAMP). Increases in cAMP activate kinases, which inhibit the phosphorylation of myosin and decrease intracellular calcium. Decreased intracellular calcium relaxes smooth muscle airways.
  • Relaxation of airway smooth muscle with subsequent bronchodilation.
  • Relatively selective for beta2 (pulmonary) receptors.
Therapeutic effects:
  • Bronchodilation.

Pharmacokinetics

Absorption: Well absorbed after oral administration but rapidly undergoes extensive metabolism.

Distribution: Small amounts appear in breast milk.

Metabolism/Excretion: Extensively metabolized by the liver and other tissues.

Half-Life: Oral 2.7–5 hr; Inhalation: 3.8 hr.
