Rivanicline (TC-2403, RJR-2403, (E)-metanicotine) is a drug which acts as a partial agonist at neural nicotinic acetylcholine receptors. It is subtype-selective, binding primarily to the α4β2 subtype. It has nootropic effects and was originally developed as a potential treatment for Alzheimer's disease,[1][2] but a second action that was subsequently found was that it inhibits the production of Interleukin-8 and thus produces an antiinflammatory effect, and so it has also been developed as a potential treatment for ulcerative colitis.[3] Rivanicline also has stimulant and analgesic actions which are thought to be mediated through stimulation of noradrenaline release,[4] and so it could also have other applications.
