西维美林 (Evoxac)

概览

Cevimeline is a muscarinic agonist with parasympathomimetic activities that is used for the symptomatic treatment of dry mouth in patients with Sjögren's Syndrome.

作用机制

Muscarinic agonists such as cevimeline bind and activate the muscarinic M1 and M3 receptors. The M1 receptors are common in secretory glands (exocrine glands such as salivary and sweat glands), and their activation results in an increase in secretion from the secretory glands. The M3 receptors are found on smooth muscles and in many glands which help to stimulate secretion in salivary glands, and their activation generally results in smooth muscle contraction and increased glandular secretions. Therefore, as saliva excretion is increased, the symptoms of dry mouth are relieved.
