Nimvastid

Product Overview

About Nimvastid

Nimvastid is a medicine that contains the active substance rivastigmine. It is available as capsules (yellow: 1.5 mg, orange: 3 mg, brownish red: 4.5 mg, and brownish red and orange: 6 mg) and as white orodispersible tablets (1.5 mg, 3 mg, 4.5 mg, and 6 mg). Orodispersible means that the tablets dissolve in the mouth. Nimvastid is a ‘generic medicine’. This means that Nimvastid is similar to a ‘reference medicine’ already authorised in the European Union (EU) called Exelon.

What it is used for

Nimvastid is used for the treatment of patients with mild to moderately severe Alzheimer’s dementia, a progressive brain disorder that gradually affects memory, intellectual ability and behaviour. It is also used to treat mild to moderately severe dementia in patients with Parkinson’s disease. The medicine can only be obtained with a prescription.

How it is used

Treatment with Nimvastid should be initiated and supervised by a doctor who has experience in the diagnosis and treatment of Alzheimer’s disease or dementia in patients with Parkinson’s disease. Treatment should only be started if a caregiver is available who will regularly monitor the use of Nimvastid by the patient. Treatment should continue as long as the medicine has a benefit, but the dose can be reduced or treatment interrupted if the patient has side effects. Nimvastid should be given twice a day, with morning and evening meals. The capsules should be swallowed whole. Nimvastid orodispersible tablets should be placed on the tongue, where they disintegrate quickly in the saliva before being swallowed. The starting dose for Nimvastid is 1.5 mg twice a day. In patients who tolerate this dose, it can be increased in 1.5-mg steps no more frequently than every two weeks, to a regular dose of 3 to 6 mg twice a day. The highest tolerated dose should be used to get the maximum benefit, but the dose should not exceed 6 mg twice a day.

How it works

The active substance in Nimvastid, rivastigmine, is an antidementia medicine. In patients with Alzheimer’s dementia or dementia due to Parkinson’s disease, certain nerve cells die in the brain, resulting in low levels of the neurotransmitter acetylcholine (a chemical that allows nerve cells to communicate with each other). Rivastigmine works by blocking the enzymes that break down acetylcholine: acetylcholinesterase and butyrylcholinesterase. By blocking these enzymes, Nimvastid allows levels of acetylcholine to be increased in the brain, helping to reduce the symptoms of Alzheimer’s dementia and dementia due to Parkinson’s disease.
