Expectorants are a class of medications used to relieve airway secretions in individuals with respiratory conditions. They work by targeting different mechanisms involved in airway muscle relaxation and mucus production, ultimately leading to symptom relief.
Some expectorants, such as mucolytics, are primarily administered orally and aim to reduce mucus production by thinning secretions and facilitating their expulsion through the respiratory tract. Other expectorants, like corticosteroids, are administered via inhalation or through an inhaler device and interact with specific chemical receptors on airway smooth muscle, promoting relaxation and narrowing of the airway.
For example, a common expectorant, such as guaifenesin (Mucinex), is used to relieve airway congestion caused by colds, flu, and other respiratory infections. It can be taken orally or inhaled via a nebule
