Reminyl ER (extended release galantamine hydrobromide)
As of June, 2006, Reminyl became available in the extended release (ER) format. It means that if you
were taking Reminyl tablets twice a day prior to June, 2006, you would now take a Reminyl ER capsule
once a day, in the morning. For example, if you are taking:
- Reminyl 4 mg. twice a day, you would now take Reminyl ER 8 mg. once a day.
- Reminyl 8 mg. twice a day, you would now take Reminyl ER 16 mg. once a day.
- Reminyl 12 mg. twice a day, you would now take Reminyl ER 24 mg. once a day.
The extended release is the same medication as the original twice-a-day version, and will have the
same effect but only needs to be taken once a day. Talk to your doctor or pharmacist if you have any
The purpose of this medication
Reminyl ER is one of a group of drugs called “cholinesterase inhibitors” which is used to treat symptoms
in people with mild to moderate Alzheimer’s disease.
In the brains of people with Alzheimer’s disease there is a progressive degeneration of nerve cells,
particularly of the cells that make acetylcholine, a chemical thought to be important for learning and
memory. Because of this, people with Alzheimer’s disease have lower brain levels of acetylcholine. It
is believed that Reminyl ER works by reducing the breakdown of acetylcholine and thus increasing the
amount of the chemical in the brain.
It has also been suggested, based on data from animal experiments, that the medication enhances
the action of acetylcholine by making the receptors it interacts with in the brain more responsive. In
the region of the brain first affected by Alzheimer’s disease, that dealing with cognition and memory,
too little acetylcholine is available at the junctions between nerve cells to get messages across to the
next nerve cell, The situation is helped, therefore, not only by preserving the acetylcholine from being
destroyed by cholinesterase, but by making the receptors more responsive to the lower amounts of
acetylcholine. Whether this effect is also true for humans is unknown.
The potential beneficial effect of Reminyl ER could lessen as the disease progresses and when fewer
cells are available to make acetylcholine.
Ongoing research is finding that combining cholinesterase inhibitors (such as Reminyl ER, Aricept or
Exelon) together with memantine (a drug used to relieve the symptoms of people with moderate to
severe Alzheimer’s disease) seems to greatly improve outcomes, sometimes more than predicted from
the sum of the effects of either drug alone. However, more and larger drug trials are needed to confirm
these promising early results.
How does it help?
Reminyl ER is intended to treat symptoms in people with mild to moderate Alzheimer’s disease. In
clinical trials, some individuals who took the drug, compared to individuals who took a placebo (a
substance which looks like the drug but has no effect), showed some improvement or no decline
in cognition (including memory, orientation and language) and global functioning (for example, the
performance of daily activities such as bathing, dressing and eating).
The medication may take as long as 12 weeks to begin working, and the type and length of response as
well as the time it takes for patients to respond to this medication will vary from person to person.
Will this medication cure Alzheimer's disease?
Reminyl ER is not a cure for Alzheimer’s disease as it does not affect the underlying degenerative
process of the disease.
Who should take this medication?
The medication is approved for people who have been diagnosed with mild to moderate Alzheimer’s
disease. The use of Reminyl ER is not advised by Health Canada outside of its approved indication.
How do you obtain this medication?
Reminyl ER can only be obtained with a prescription from a doctor after a diagnosis of Alzheimer’s
disease has been made.
A reminder: This medication has been prescribed only for you or for the person you are caring for. It
must not be given to anybody else or used for any other illness.
