Galantamin is a medicine used to treat a form of dementia called Alzheimer's disease. The active ingredient galantamine is not a cure for Alzheimer's disease, but aims to slow its progression and improve symptoms such as loss of the ability to concentrate and communicate. It is prescribed for mild to moderately severe Alzheimer's dementia.
What is Galantamin?
Galantamin contains the active ingredient galantamine. It works by slowing the breakdown of a neurotransmitter in the body called acetylcholine, a chemical substance that sends signals to other nerve cells in the brain. Alzheimer's disease causes the brain to be less sensitive to acetylcholine which, in turn, leads to the gradual and irreversible loss of certain brain functions such as memory.
Galantamin slows down the breakdown of acetylcholine. The result is an improvement in the levels and activity of acetylcholine in the brain. This improves information transmission between cells and slows down the deterioration of brain functions.
When is Galantamin used?
Galantamin is used to treat mild to moderately severe Alzheimer's dementia. Alzheimer's disease is the most common type of dementia. The symptoms of Alzheimer's disease include:
- Difficulty performing daily tasks, such as turning the TV or radio on or off, getting dressed, cooking or grocery shopping.
- Misplacing things or putting things in unusual places.
- Changes in mood and personality.
- Losing track of the date or time.
- Restlessness or agitation.
- Decreased vision.
Galantamin is not a cure for Alzheimer's disease, but it can slow its progression, and symptoms such as memory loss. However, it does not work equally well for everyone.
How is Galantamin used?
Always use this medicine as directed by a doctor. The general guidelines for use are as follows:
- Galantamin capsules should be taken in the morning, with food.
- The capsules should be swallowed whole with a drink of water.
- If you are switching from regular tablets or oral solution to capsules, take the first capsule on the morning after having taken your last tablet or dose of oral solution.
- It is important to drink plenty of fluids (at least eight glasses a day) to keep yourself hydrated. This helps prevent side effects.
- Does this medicine affect your driving? This medicine may cause side effects that make you feel less alert than normal (e.g. dizziness or tiredness). Stay out of traffic if you do experience these side effects.
- Do not drink alcohol while taking Galantamin as this is likely to worsen the side effects.
- If you have forgotten to take a tablet, skip the missed dose and continue your regular dosing schedule. Never take a double dose to make up for the forgotten one. If you forget to take your medicine for more than one week, contact your doctor before taking any more medicine.
