Like some (but not all) COPD medications, Brovana is inhaled using a nebulizer, a device that changes liquid medications into fine droplets that are inhaled into the lungs.
The medication is made for Sunovion Pharmaceuticals, Inc.
In normal, healthy lungs, air can move easily in and out of the lungs through a network of airways. However, certain lung diseases (such as COPD) cause the muscles around these airways to tighten. This narrows the airways and makes it harder to breathe. This is called bronchospasm.
Brovana is part of a class of drugs called beta-adrenergic receptor agonists, or beta agonists for short. Beta agonists stimulate beta receptors in the body, including those on the muscles around airways. This stimulation causes the muscles to relax, which opens up the airways and allows more air to get into and through the lungs. Brovana also has some effects on decreasing the activity of mast cells in the lungs, which play an important role in inflammation and allergic reactions.
Beta agonists are usually divided into two categories: short-acting and long-acting beta agonists. Brovana is a long-acting beta agonist. As a long-acting beta agonist, it is used on a scheduled basis to help prevent symptoms; it is not used as a "rescue" medication (to be used when needed).
