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 (Caucasian snowdrop, Voronov's snowdrop), Galanthus woronowii (Amaryllidaceae) and related genera like Narcissus (daffodil)),[1] Leucojum (snowflake), and Lycoris including Lycoris radiata (Red Spider Lily).
Studies of usage in modern medicine began in the Soviet Union in the 1950s. The active ingredient was extracted, identified, and studied, in particular in relation to its acetylcholinesterase (AChE)-inhibiting properties. The bulk of the work was carried out by Soviet pharmacologists M. D. Mashkovsky and R. P. Kruglikova–Lvova, beginning in 1951.[2] The work of Mashkovsky and Kruglikova-Lvova was the first published work that demonstrated the AChE-inhibiting properties of galantamine.[3]
The first industrial process was developed in Bulgaria by prof. Paskov in 1959 (Nivalin, Sopharma) from a species traditionally used as a popular medicine in Eastern Europe, and, thus, the idea for developing a medicine from these species seems to be based on the local use (i.e., an ethnobotany-driven drug discovery).[4][5]
Galantamine has been used for decades in Eastern Europe and Russia for various indications such as treatment of myasthenia, myopathy, and sensory and motor dysfunction associated with disorders of the central nervous system. In the US, it is FDA approved for the treatment of Alzheimer's disease.
It is available in both a prescription form and as an over the counter supplement.

Pharmacology[edit]
Galantamine in its pure form is a white powder. Galantamine is a competitive and reversible cholinesterase inhibitor. It reduces the action of AChE and therefore tends to increase the concentration of acetylcholine in the brain. It is hypothesized that this action might relieve some of the symptoms of Alzheimer's. It is also an allosteric ligand at nicotinic acetylcholine receptors.
The atomic resolution 3D structure of the complex of galantamine and its target, acetylcholinesterase, was determined by X-ray crystallography in 1999 (PDB code: 1DX6; see complex).[6] There is no evidence that galantamine alters the course of the underlying dementing process.[7] Galantamine has also shown activity in modulating the nicotinic cholinergic receptors on cholinergic neurons to increase acetylcholine release.[8]
Pharmacokinetics[edit]
Absorption of galantamine is rapid and complete and shows linear pharmacokinetics. It is well absorbed with absolute oral bioavailability between 80 and 100%. It has a half-life of seven hours. Peak effect of inhibiting acetylcholinesterase was achieved about one hour after a single oral dose of 8 mg in some healthy volunteers.
Plasma protein binding of galantamine is about 18%, which is relatively low.
Metabolism[edit]
Approximately 75% of a dose of galantamine is metabolised in the liver. In vitro studies have shown that Hepatic CYP2D6 and CYP3A4 are involved in galantamine metabolism.
For Razadyne ER (the once-a-day formulation), CYP2D6 poor metabolizers had drug exposures that were approximately 50% higher than for extensive metabolizers. About 7% of the population has this genetic mutation; however, because the drug is individually titrated to tolerability, no specific dosage adjustment is necessary for this population.
Clinical use[edit]
Indications[edit]
Galantamine is indicated for the treatment of mild to moderate vascular dementia and Alzheimer's.[9][10]
Available forms[edit]
The product is supplied in both a prescription form as well as an over the counter supplement. in twice-a-day tablets, in once-a-day extended-release capsules, and in oral solution. The tablets come in 4 mg, 8 mg, and 12 mg forms. The capsules come in 8 mg, 16 mg, and 24 mg forms.
Adverse events[edit]
In clinical trials, galantamine's side effect profile was very similar to that of other cholinesterase inhibitors, with gastrointestinal symptoms being the most notable and most commonly observed. In practice, some other cholinesterase inhibitors might be better tolerated; however, a careful and gradual titration over more than three months may lead to equivalent long-term tolerability.[11]
Other uses[edit]
Supplement for lucid dream and out-of-body experience[edit]
Some people who practice lucid dream (LD) or out-of-body experience (OBE) use galantamine to increase their odds to achieve LD or OBE.[12][13][14] By taking small amount of galantamine (around 4 to 8 mg) after five to six hours of deep sleep and practice an induction technique such as meditation, MILD or WILD [1] many people report more success with galantamine.[15]
There are also reports claiming that taking galantamine without proper induction technique will not lead to LD or OBE but will result in only a vivid dream instead. It should also be noted that, due to a long half-life, galantamine will stay in the body for a period of up to and over 48 hours. As such, it is advisable to space out the use of galantamine over a period of three days so that the body does not build a resistance to the drug, ruining its effectiveness.[12]
Galantamine used with choline bitartrate or Alpha-GPC can dramatically increase one's odds of becoming lucid and increase memory consolidation during dreaming.[citation needed] Some people report mixing galantamine with other nootropic can enhance the degree of lucidity, but this is still controversial, since some mixtures may work for some people, but lead to failure for others.
Sleep aid[edit]
Galantamine has been used as a sleep aid, Galantamine has been anecdotally described both to help people fall asleep and increasing the quality of sleep once someone falls asleep. Extensive research and sleep studies have not been conducted, but initial microbiological research suggests that Galantamine does have properties that can aid patients suffering from insomnia.
Nootropic[edit]
Along with other cholinergics or acetylcholinesterase inhibitors such as Huperzine A, galantamine also has been used as nootropic or "brain enhancer" to enhance memory in brain-damaged adults.[16]
Augmentative therapy in autistic children[edit]
Galantamine given in addition to Risperidone to autistic children has been shown to improve some of the symptoms of autism (irritability, lethargy and social withdrawal).[17]
Caution[edit]
The U.S. Food and Drug Administration (FDA) and international health authorities have published an alert based on data from two studies during the treatment by galantamine of mild cognitive impairment (MCI); higher mortality rates were seen in drug-treated patients.[18][19] On April 27, 2006, FDA approved labeling changes concerning all form of galantamine preparations (liquid, regular tablets, and extended release tablets) warning of the risk of bradycardia (slow resting heart rate), and sometimes atrioventricular block, especially in predisposed persons. At the same time, the risk of syncope (fainting) seems to be increased relative to placebo. "In randomized controlled trials, bradycardia was reported more frequently in galantamine-treated patients than in placebo-treated patients, but was rarely severe and rarely led to treatment discontinuation" [20] These side effects have not been reported in Alzheimer's Disease related studies.[21]

Galantamine is produced from natural resources and a patented total synthesis process. Many other synthetic methods exist but have not been implemented on an industrial scale.
