IGFLOW 400 is a combination medication used to treat asthma and chronic obstructive pulmonary disease (COPD). It contains two active ingredients: budesonide and formoterol.

Budesonide is a corticosteroid that helps reduce inflammation in the airways, which is a common symptom of asthma and COPD. It works by decreasing the production of certain chemicals in the body that cause inflammation.

Formoterol is a long-acting beta-agonist that helps relax the muscles in the airways, making it easier to breathe. It works by stimulating certain receptors in the lungs, which leads to the relaxation of the smooth muscles surrounding the airways.
