DUOVA INHALER – 9MCG + 6MCG
Duova Inhaler -9MCG + 6MCG is prescribed for the management of chronic obstructive pulmonary
disease (COPD) whose symptoms are quite similar to asthma including- shortness of breath, wheezing,
chronic cough with sputum production, tightness of the chest etc.
The two main active ingredients of Duova Inhaler -9MCG + 6MCG are- Tiotropium Bromide and
Formoterol Fumarate Dihydrate
How does it work:
Formoterol (long-acting beta-agonist) bronchodilator in Duova Inhaler works locally in the lungs and
helps in the smooth muscle in the airway walls to widen airways. Tiotropium (long-acting
anticholinergic) in Duova Inhaler works on specific receptors (muscarinic receptors) in the lung
bronchioles to stop the interaction of acetylcholine (a neurotransmitter or chemical messenger of the
nervous system) with muscarinic receptors. Both of these ingredients together reduces bronchospasm
and assists in relieving from the COPD symptoms by increasing air flow into the lungs.
How to use this?
Use Duova Inhaler as prescribed by your doctor, normally 2 puffs daily. If needed, use the spacer device
