SponsorChiesi Farmaceutici S.p.A.
Drug classLABA/LAMA combination (Long-Acting Beta-2 Agonist / Long-Acting Muscarinic Antagonist)
TargetBeta-2 adrenergic receptor and M3 muscarinic receptor
ModalitySmall molecule
Therapeutic areaRespiratory / Pulmonology
PhasePhase 3

Mechanism of action

The drug works through two complementary pathways: the beta-2 agonist component stimulates beta-2 adrenergic receptors to relax airway smooth muscle, while the muscarinic antagonist blocks M3 receptors to prevent acetylcholine-induced bronchoconstriction. This dual mechanism provides synergistic bronchodilation and improved lung function in COPD patients.
