Galantamine Hydrobromide (Reminyl®)

Supports proper nicotinic receptor activity

Reminyl® is a brand name for galantamine, which is a phytonutrient extracted from the common snowdrop plant.

It’s been shown to act as an acetylcholinesterase inhibitor and block the age-related breakdown of the neurotransmitter acetylcholine (ACh). This has important implications for those concerned with Alzheimer’s since galantamine can improve ACh levels and it is the principal neurotransmitter ‘lost’ in the disease. Accordingly, this has become the principle use and focus for galantamine around the world.

In addition, galantamine also supports proper nicotinic receptor activity, an effect known to influence memory function. It may be this action that has led to it being utilised for other generalised states of vascular dementia. 

Other off-label uses for galantamine have been detailed for the alleviation of depression. There is also anecdotal evidence that points to galantamine having a potential role in weight loss, due to its appetite suppressant effects.

Reminyl® is used in the treatment of mild to moderately severe Alzheimer’s disease or related dementia. Reminyl® works to increase the amount of acetylcholine in the brain, which dementia or Alzheimer’s sufferers are believed to have a lack of. This substance is what sends messages between brain cells, thus a lack will alter brain function.

The symptoms of low acetylcholine include confusion, progressive memory loss and behavioral changes.
