1) Galantamine inhibits acetylcholinesterase, the enzyme that breaks down acetylcholine (the brain neurotransmitter necessary for learning and memory).
2) Galantamine stimulates brain nicotinic receptors and reduces the build up of amyloid plaque (deposits containing amyloid peptide and dead neurons) in the brain. Galantamine produces two interesting side benefits. A mild anti-depressant effect has been reported and users are noticing a reduction in body weight, probably a result of the nicotinic receptor stimulation.
