Nourianz® (istradefylline)
for Parkinson’s Disease

Nourianz (istradefylline) is an adenosine receptor antagonist used with levodopa and carbidopa to treat "wearing-off" episodes in Parkinson's disease, which cause muscle stiffness and loss of control. It works by blocking adenosine receptors in the brain, helping to restore balance between adenosine and dopamine, which are chemicals that regulate movement. This action may help reduce Parkinson's symptoms and improve motor control.
