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.
1 While levodopa is converted in the brain into dopamine, dopamine agonists actually mimic the effects of dopamine without having to be converted. 2  Apart from Carbidopa-Levodopa, dopamine agonists are often the first medication prescribed to treat PD, but can also be used in later stages of PD with carbidopa/levodopa.
