Galantamine (Nivalin, Razadyne, Razadyne ER, Reminyl, Lycoremine) is used for the treatment of mild to moderate Alzheimer's disease and various other memory impairments, in particular those of vascular origin. It is an alkaloid that is obtained synthetically or from the bulbs and flowers of Galanthus caucasicus (Caucasiansnowdrop), Galantus woronowii (Voronov's snowdrop), and some other members of the family Amaryllidaceae such as Narcissus, Leucojum aestivum (snowflake), and Lycoris including Lycoris rardiata.

In addition to uses in Alzheimer’s disease, galantamine has been used to treat myasthenia, myopathy, muscular dystrophy, and sensory and motor dysfunction associated with disorders of the central nervous system. Research has indicated that galantamine may prove useful both in the treatment of organophosphate poisoning and in the treatment of autism in children and adolescents.
