Pulmosmart 400 mg Capsule 30's contains the corticosteroid Budesonide and the formoterol (LABA - long-acting beta-agonists or bronchodilator). Budesonide is a member of the corticosteroid class, which reduces inflammation and swelling by working inside the cells lining the nasal tube and the airways and halting the production of certain molecules that cause allergic reactions and inflammatory reactions. As a result, it eases the discomfort caused by sneezing, a runny or plugged nose, and sinuses. Asthma and COPD patients can breathe more easily thanks to Formoterol, a long-acting beta-agonist or bronchodilator that relaxes and expands the muscles in the respiratory system.Disclaimer:For more information contact your physician.
