Levodopa (L-dopa). A substance used in the treatment of Parkinson's disease. Levodopa can cross the blood-brain barrier that protects the brain. Once in the brain, it is converted to dopamine and thus can replace the dopamine lost in Parkinson's disease.
Levodopa is almost always given in combination with the drug carbidopa, which prevents the nausea that can be caused by levodopa alone. Carbidopa is also a levodopa enhancer. When added, carbidopa enables a much lower dose of levodopa (80% less!) and helps reduce the side effects of nausea and vomiting. Pills containing both drugs are often labeled âcarbidopa-levodopa,â with the active components listed in alphabetical order.
