Indications & Uses

Pharmacology

This preparation contains two bronchodilators. One is glycopyrronium, a long-acting muscarinic antagonist (LAMA), and the other is formoterol, a long-acting β2-adrenergic agonist (LABA) that starts working rapidly. Glycopyrronium binds with similar affinity to the muscarinic receptor subtypes M1 to M5. In the airways, its effect comes from blocking the M3 receptor at the smooth muscle, which leads to bronchodilation. Formoterol relaxes airway smooth muscle directly. It does this by activating adenylyl cyclase, which raises the level of cyclic AMP.
