VMAT2 inhibitor

A VMAT2 inhibitor is a medication that blocks a specific protein called vesicular monoamine transporter 2 (VMAT2). This protein helps transport mood-related chemicals like dopamine, serotonin, and norepinephrine into storage spots inside nerve cells. By inhibiting VMAT2, the drug reduces the amount of these chemicals released during nerve activity, which can help manage symptoms of disorders like Huntington’s disease or Tourette syndrome. Essentially, VMAT2 inhibitors modulate brain chemistry by controlling how much of certain chemicals are stored and released, helping to balance brain function and reduce unwanted movements or behaviors.
