Uses For carbidopa, entacapone, and levodopa
Carbidopa, entacapone, and levodopa combination is used to treat Parkinson's disease, sometimes called shaking palsy. Parkinson's disease is a disorder of the central nervous system (brain and spinal cord).
Dopamine is a naturally occurring substance in the brain that helps provide control of movement and activities such as walking and talking. In patients with Parkinson's disease, there is not enough dopamine in some parts of the brain. Levodopa (a component of carbidopa, entacapone, and levodopa) enters the brain and helps replace the missing dopamine, which allows people to function better. By increasing the amount of dopamine in the brain, levodopa helps control symptoms and helps you to perform daily activities such as dressing, walking, and handling utensils.
carbidopa, entacapone, and levodopa is a combination of three different medicines. carbidopa, entacapone, and levodopa is known as a levodopa therapy. The difference between carbidopa, entacapone, and levodopa and other levodopa treatments is that carbidopa, entacapone, and levodopa contains entacapone. Entacapone helps levodopa last longer by blocking a substance called COMT enzyme. This enzyme breaks down levodopa before it reaches the brain. When less levodopa is broken down, more is available to the brain. Increased availability of levodopa may lead to smoother and steadier levels of dopamine in the brain, which may provide better symptom control for longer periods each day. This may lead to improvement in daily activities.
carbidopa, entacapone, and levodopa is available only with your doctor's prescription.
