How Does Rivamer 4.5 mg Work?

Increases Acetylcholine:

When we have diseases that affect the brain, like Alzheimer’s, the amount of Acetylcholine in our bodies goes down. Acetylcholine is an important chemical that helps us with our memory, learning, and thinking.

Blocks Breakdown Enzymes:

Rivastigmine works by binding to and stopping the action of two enzymes: acetyl cholinesterase and butyryl cholinesterase. These enzymes break down a chemical called acetylcholine. Rivastigmine blocks them so acetylcholine can stay in the body longer.

Improves signal transmission:

Rivamer makes sure that something called acetylcholine is where it needs to be at the places where our nerve cells meet. Our brain cells can communicate more effectively with each other, and that is helpful for Rivamer to do.
