In the management of Parkinson's disease, due to the chronic nature of Parkinson's disease (PD), a broad-based program is needed that includes patient and family education, support-group services, general wellness maintenance, exercise, and nutrition. At present, no cure for the disease is known, but medications or surgery can provide relief ...
Levodopa-induced dyskinesia (LID) is a form of dyskinesia associated with levodopa (l-DOPA), used to treat Parkinson's disease. It often involves hyperkinetic movements, including chorea, dystonia, and athetosis. [1] In the context of Parkinson's disease (PD), dyskinesia is often the result of long-term dopamine therapy.
Levodopa is an amino acid and a substituted phenethylamine and catecholamine. [3] Analogues and prodrugs of levodopa include melevodopa, etilevodopa, foslevodopa, and XP-21279. Some of these, like melevodopa and foslevodopa, are approved for the treatment of Parkinson's disease similarly to levodopa.
Parkinson's disease (PD) is a progressive neurological disorder resulting from the death of cells in the substantia nigra that contain and produce dopamine. People with PD may develop disturbance in their motor activities. Some activities can be tremor or shaking, rigidity and slow movements (bradykinesia).
Parkinson's typically manifests in individuals over 60, with about one percent affected. In those younger than 50, it is termed "early-onset PD". No cure for Parkinson's is known, and treatment focuses on alleviating symptoms. Initial treatment typically includes L-DOPA, MAO-B inhibitors, or dopamine agonists.
COMT inhibitors are indicated for the treatment of Parkinson's disease in combination with levodopa and an aromatic L-amino acid decarboxylase inhibitor (e.g. carbidopa or benserazide). The therapeutic benefit of using a COMT inhibitor is based on its ability to prevent the methylation of levodopa to 3- O -methyldopa , thus increasing the ...
