An aqueous solution or gel that is useful in treating excessive dryness of the mouth (xerostomia).
A remedy designed to alleviate the symptoms of a persistently dry mouth, which can occur as a side effect of certain medications, radiotherapy, or as a result of Sjögren’s syndrome (an autoimmune disorder characterized by the immune system attacking the body’s own tissues), is known as artificial saliva. Available in the form of sprays, gels, or pastilles, artificial saliva is carefully formulated to closely resemble natural saliva in its composition and properties.
