Expectorant

An expectorant is a medication that is taken to help clear mucus from the respiratory tract and make breathing easier. It is often used to treat coughs caused by the common cold, bronchitis, and other respiratory illnesses. Expectorants work by loosening and thinning the mucus, making it easier for the body to expel it. In addition, some expectorants may also have an anti-inflammatory effect, helping to reduce swelling in the airways and make breathing easier. The most common expectorants are guaifenesin, ammonium chloride, and iodinated glycerol.
