The reference site for Rivastigmine

Rivastigmine (sold under the trade name Exelon) is a parasympathomimetic or cholinergic agent for the treatment of mild to moderate dementia of the Alzheimer’s type and dementia due to Parkinson’s disease.

WHAT IS Rivastigmine?

Rivastigmine improves the function of nerve cells in the brain, and works by preventing the breakdown of a chemical called acetylcholine. People with dementia usually have lower levels of this chemical, which is important for the processes of memory, thinking, and reasoning.

Rivastigmine is approved for mild to moderate dementia of the Alzheimer’s type and for mild to moderate dementia related to Parkinson’s disease.

It is sold in the US under that trade name Exelon® but is also known as Prometax® in the UK. It was previously known as SDZ ENA 713.

FDA Information

Rivastigmine was first developed by Novartis for the treatment of mild to moderate dementia of the Alzheimer’s type, and launched in the the European Union in 1998 and in the US in 2000.

In 2006, it became the first product approved by the US FDA for the treatment of mild to moderate dementia associated with Parkinson’s Disease. A prescription is required for this medicine.

Please visit the official site of the FDA for further information.

Why is this medication prescribed?

Rivastigmine is used to treat mild to moderate dementia caused by Alzheimer’s or Parkinson’s disease.

Drug class and mechanism: 

Rivastigmine is in a class of drugs called cholinesterase inhibitors that also includes tacrine (Cognex®), donezepil (Aricept®), and galantamine (Reminyl®).

Cholinesterase inhibitors block the action of acetylcholinesterase, the enzyme responsible for the destruction of acetylcholine. Acetylcholine is one of several neurotransmitters in the brain, chemicals that nerve cells use to communicate with one another. Reduced levels of acetylcholine in the brain are believed to be responsible for some of the symptoms of Alzheimer’s disease. By blocking the enzyme that destroys acetylcholine, rivastigmine increases the concentration of acetylcholine in the brain, and this increase is believed to be responsible for the improvement in thinking seen with rivastigmine.

For most patients who take rivastigmine there will not be a dramatic improvement, but the progression of symptoms may be slowed. After 6 months of treatment with rivastigmine, 25-30% of patients scored better on tests of memory, understanding, and activities of daily living as compared with only 10-20% of patients receiving placebo (a dummy or sugar pill).

Other uses for this medicine

Rivastigmine also is used sometimes to treat Lewy body dementia.

However, it is important that you talk to your doctor about the possible risks of using this drug for your particular condition.
