Mechanism Of Action Of Duova Inhaler 9mcg/6mcg

Duova Inhaler 9mcg/6mcg works through a dual-action mechanism using two active ingredients: Tiotropium and Formoterol. Together, they help open the airways and improve breathing in COPD patients.

1. Formoterol (Long-Acting β2-Agonist – LABA)

• Stimulates β2 receptors in airway smooth muscles
• Causes muscle relaxation (bronchodilation)
• Leads to widening of airways
• Provides fast and long-lasting relief

Result: Easier airflow and reduced breathlessness

2. Tiotropium (Long-Acting Anticholinergic – LAMA)

• Blocks muscarinic (M3) receptors in the lungs
• Prevents acetylcholine-induced bronchoconstriction
• Reduces airway tightening and mucus secretion

Result: Keeps the airways open for a longer duration

Combined Effect (Synergistic Action)

• Dual pathways → stronger bronchodilation
• Improves lung function and airflow

Reduces COPD symptoms like:

• Wheezing
• Shortness of breath
• Chest tightness
