Chemical Properties

Pale Yellow Solid

Uses

Formoterol is a selective β2-adrenergic receptor agonist. Formoterol is used as an antiasthmatic.

Uses

ForMoterol FuMarate Dihydrate is a selective β2-adrenergic receptor agonist,it is used as an antiasthmatic.

Biological Activity

Potent, selective and long-acting β 2 -adrenoceptor agonist. Displays 330-fold selectivity for β 2 over β 1 receptors (pK d values are 8.12 and 5.58 respectively). Potently relaxes guinea pig trachea (pD 2 = 9.29), and is longer-acting and 100-fold more potent than salbutamol.

Biochem/physiol Actions

β2-Adrenoreceptor agonist.

Drug interactions

The efficacy and tolerability of glycopyrronium/formoterol fumarate metered dose inhaler, a fixed-dose combination of glycopyrronium/formoterol fumarate dihydrate 14.4/10 μg (equivalent to glycopyrrolate/formoterol fumarate 18/9.6 μg) delivered by metered dose inhaler using innovative co-suspension delivery technology, was investigated in patients (n = 292) with COPD [12C]. There were no meaningful pharmacokinetic interactions, whether drug–drug or due to formulation, between glycopyrronium and formoterol following treatment with formulated using a new co-suspension delivery technology. The incidence of cardiovascular events of special interest was low (stroke, 0%–0.4%; cardiac ischemia, 0.4%–2.3%; cardiac failure, 1.3%–2.5%; arrhythmia, 1.3%–3.2%), and no important trends in clinical laboratory results, vital signs, or electrocardiograms were observed[1].
