8.2 Description
Formoterol fumarate is a β2-selective adrenergic agonist useful in the treatment of bronchial asthma. It s potency and duration of action a r e reported to exceed those of salbutamol, as is its ability to inhibit allergic and non-allergic histamine release.
8.3 Chemical Properties
Crystalline Solid
8.4 Originator
Yarnanouchi (Japan)
8.5 Uses
Formoterol fumarate is a potent β2-AR agonist.
8.6 Uses
A potent β2-AR agonist
8.7 Uses
long-acting β 2-agonist, anti-asthmatic
8.8 Uses
A selective 2-adrenergic receptor agonist. Used as an antiasthmatic
8.9 Uses
8.10 Brand name
Foradil (Novartis);ATOCK.
8.11 Mechanism of action
This is believed to result from formoterol's greater water solubility, allowing it to get to the receptor sites faster, whereas its moderate lipophilicity keeps it in the lungs longer. It is indicated for the long-term maintenance treatment of asthma and for patients with symptoms of nocturnal asthma who require regular treatment with inhaled, short-acting, β2-agonists. It is not indicated for patients whose asthma can be managed by occasional use of inhaled, short-acting, β2-agonists. Formoterol is available only as a powder in a capsule for administration via the aerosolizer. Patients should be cautioned not to take the capsules orally and to keep them in a safe place to avoid accidental oral administration.
8.12 Clinical Use
Formoterol has a β-directing N-isopropyl-p-methoxyphenyl group and a unique m-formamide and p-hydroxyphenyl ring, which provides selectivity for β2-receptors. It is resistant to MAO and COMT, making it a long-acting agonist. Formoterol has a more rapid onset as compared to salmeterol while maintaining the same long duration of action.
