Duova Inhaler general information

What is Duova Inhaler used for?

Duova inhaler is a combination treatment used for the long-term maintenance treatment of chronic obstructive pulmonary disease (COPD), which is a progressive obstructive airways disease that usually gets worse with time. The symptoms of COPD are caused by bronchospasm and are similar to asthma, including tightness of the chest, wheezing and shortness of breath, as well as chronic cough with sputum production because the lung tissues have become damaged. Duova Inhaler provides improved action to open airways and improve breathing, which helps relieve symptoms, where a single medication has not been sufficiently effective.

How does Duova Inhaler work?

Duova Inhaler contains two bronchodlators that are used for long-term treatment of chronic obstructive pulmonary disease (COPD). Formoterol in Duova Inhaler is a potent, selective, long-acting beta-agonist that acts locally in the lungs and works as a bronchodilator by relaxing the smooth muscle in the airway walls to widen the airways. Tiotropium in Duova Inhaler is a long-acting anticholinergic that acts on specific receptors (muscarinic receptors) in the bronchioles of the lung and inhibits the interaction of acetylcholine (a neurotransmitter or chemical messenger of the nervous system) with muscarinic receptors, which prevents spasm of the airway wall caused by acetylcholine. The synergistic action (interacting to enhance the action of each other) of the two drugs working together by different mechanisms, reduces bronchospasm (contraction of the airways) to a greater extent than would be provided by each drug alone and increases air flow into the lungs, relieving symptoms of COPD such as chronic cough with sputum production, tightness of the chest, wheezing and shortness of breath.

What does Duova Inhaler contain?

Duova Inhaler is a metered dose inhaler containing a combination of two active ingredients; formoterol fumarate dihydrate (9mcg), a long-acting beta-agonist, and tiotropium bromide monohydrate (6mcg) a long-acting anticholinergic used to treat chronic obstructive pulmonary disease (COPD). Each dose delivers an inhalation aerosol containing 9mcg formoterol and 6mcg tiotropium. Each inhalation canister contains 200 doses.

Treating chronic obstructive pulmonary disease (COPD) with Duova Inhaler

Duova Inhaler contains two bronchodlators, formoterol and tiotropium that are used in combination for long-term treatment of chronic obstructive pulmonary disease (COPD). Formoterol and tiotropium in Duova Inhaler work synergistically by different mechanisms, to relax the muscles of the airways, reducing bronchospasm (narrowing of the airways) and increasing air flow into the lungs. Formoterol is a potent, selective, long-acting beta-agonist that acts locally in the lungs and works as a bronchodilator by relaxing the smooth muscle in the airway walls to widen the airways. Tiotropium is a long-acting anticholinergic that acts on specific receptors (muscarinic receptors) in the bronchioles of the lung and inhibits the interaction of acetylcholine (a neurotransmitter or chemical messenger of the nervous system) with muscarinic receptors, which prevents spasm of the airway wall caused by acetylcholine. Chronic obstructive pulmonary disease (COPD) is a progressive obstructive airways disease that usually gets worse with time, with symptoms similar to asthma caused by bronchospasm, including tightness of the chest, wheezing and shortness of breath, as well as chronic cough with sputum production because the lung tissues have become damaged. Duova Inhaler provides improved action to open airways and improve breathing, which helps relieve symptoms, where a single medication has not been sufficiently effective.
