What Is Nourianz?
Nourianz (istradefylline) is an adenosine receptor antagonist indicated as adjunctive treatment to levodopa/carbidopa in adult patients with Parkinson's disease (PD) experiencing "off" episodes.
What Is Stalevo?
Stalevo (carbidopa, levodopa and entacapone) is a combination of several medications used to treat Parkinson symptoms such as muscle stiffness, tremors, spasms, and poor muscle control. Levodopa is converted to a chemical called dopamine in the brain. Symptoms of Parkinson's disease may be caused by low levels dopamine in the brain. Carbidopa helps prevent the breakdown of levodopa before it can reach the brain and take effect. When used with carbidopa and levodopa, entacapone increases levels of levodopa in the body.
