Galantamin
Galantamin - General Information
A benzazepine derived from norbelladine. It is found in galanthus and other amaryllidaceae. It is a cholinesterase inhibitor that has been used to reverse the muscular effects of gallamine triethiodide and tubocurarine and has been studied as a treatment for alzheimer disease and other central nervous system disorders.

Pharmacology of Galantamin
Galantamin is a parasympathomimetic, specifically, a reversible cholinesterase inhibitor. Galantamin is indicated for the treatment of mild to moderate dementia of the Alzheimer's type. Galantamin is postulated to exert its therapeutic effect by enhancing cholinergic function. This is accomplished by increasing the concentration of acetylcholine through reversible inhibition of its hydrolysis by acetylcholinesterase. If this proposed mechanism of action is correct, Galantamin's effect may lessen as the disease process advances and fewer cholinergic neurons remain functionally intact. There is no evidence that Galantamin alters the course of the underlying dementing process.
Galantamin for patients
Galantamine is used to treat the symptoms of Alzheimer's disease (AD; a brain disease that slowly destroys the memory and the ability to think, learn, communicate and handle daily activities). Galantamine is in a class of medications called acetylcholinesterase inhibitors. It works by increasing the amount of a certain natural substance in the brain that is needed for memory and thought. Galantamine may improve the ability to think and remember or slow the loss of these abilities in people who have AD. However, galantamine will not cure AD or prevent the loss of mental abilities at some time in the future.
