Cevimeline, a parasympathomimetic and muscarinic agonist, affects M1 and M3 receptors. Cevimeline has been shown to treat dry mouth and Sj gren's syndrome. It is also used to reduce Xerostomia symptoms and increase salivary flow in head and neck cancer survivors after radiotherapy.
Cevimeline HCl is an agonist of cholinergic that binds to muscarinic receptors. Muscarinic agonists in sufficient dosage can enhance the secretion of exocrine glands, such as salivary and sweat glands.
