Galantamine (Nivalin, Razadyne, Razadyne ER, Reminyl, Lycoremine) is used for the treatment of mild to moderate Alzheimer's disease and various other memory impairments, particularly those of vascular origin. It is an alkaloid that is obtained synthetically or from the bulbs and flowers of Galanthus Caucasicus (Caucasian snowdrop, Voronov's snowdrop), Galanthus woronowii (Amaryllidaceae) and related genera like Narcissus (daffodil)), Leucojum(snowflake) and Lycoris including Lycoris radiata (Red Spider Lily).

Ki sa ki pwodui sa a?
Galanthamine is natural extracted from lycoris radiate,is a tertiary alkaloid derived from snow drop and closely related species. It acts as a reversible competitive acetylcholinesterase (ACHE) inhibitor, while acts weaker on butyrylcholinesterse(BuChE).it is used in the treatment of disorders of the central nerbous system and may be used as an antidote to nonpolarizing muscle relaxants.Galanthamine hydrobromide is a white to almost white powder;sparingly soluble in water; insoluble chloro.form,ether and alcohol.
Aplikasyon
Galantamine hydrobromide also called as 11-methyl-3-methoxy-4a, 5, 9, 10, 11, 12-hexahydro-6H-benzene and furans [3a, 3, 2-ef] [2] benzazepine-6-ol hydrobromide, is an alkaloid isolated from Lycoris plants. In the 1960 s, China had first successfully isolated it from domestic Medicago Lycoris and Lycoris radiata, The hydrobromide salt is white crystalline powder and is odorless with bitter taste. It is soluble in water. The absorption coefficient (50 ug in 1 ml of water): at 289nm wavelength, it has an absorption coefficient of 79.6~86.2. It is mainly applied to myasthenia gravis, poliomyelitis sequelae and resting stage as well as being used for the treatment of children with cerebral paralysis, polyneuritis, radiculitis and sensory motor disorders caused by nerve disorders or trauma. It is clinically also used for the treatment of Alzheimer's disease as well as treatment of dementia and memory disorders caused by the organic disease of the brain with significant therapeutic effect.
