Question 3

How does Ingrezza work?

Accepted Answer

Mechanism of Action

Ingrezza is classified as a vesicular monoamine transporter 2 (VMAT2) inhibitor. It works by blocking a specific protein in the brain called VMAT2, which is responsible for moving certain chemicals into nerve cells.

Regulating Brain Chemicals

The primary chemical affected by this medication is dopamine. Dopamine is a natural substance that helps the brain control muscle movements. In people with certain movement disorders, there may be an imbalance or overactivity of dopamine in the parts of the brain that manage motor function.

By blocking the VMAT2 protein, Ingrezza reduces the amount of dopamine released in the brain. This reduction helps to:

Control involuntary, repetitive body movements.

Manage jerky or irregular motions associated with chorea.

Although the way the drug interacts with the VMAT2 protein is established, the precise mechanism by which it improves specific movement symptoms is not completely understood.
