Patients with dry cough can also undergo nebulization, a nebulized inhalation therapy that involves the formation of a mist of medication into the respiratory tract to achieve a series of effects such as anti-inflammatory, sputum thinning, and help with sputum drainage. For dry cough, appropriate addition of airway dilators, as well as nebulization, can make the symptoms of dry cough disappear, while the addition of saline, which helps to drain the phlegm, is effective in improving the dry cough that occurs in pharyngitis, as well as the dry cough that occurs in the lower respiratory tract. Antibiotics, like gentamicin, can be added to the nebulizing solution, as well as by adding chymotrypsin, dexamethasone, and budesonide formoterol. For dry cough, nebulizing should be done at the same time to treat the cause.
