L-dopa synthesis from l-tyrosine
l-DOPA crosses the protective blood–brain barrier, whereas dopamine itself cannot. Thus, l-DOPA is used to increase dopamine concentrations in the treatment of Parkinson's disease, Parkinsonism, dopamine-responsive dystonia and Parkinson-plus syndrome. The therapeutic efficacy is different for different kinds of symptoms. Bradykinesia and rigidity are the most responsive symptoms while tremors are less responsive to levodopa therapy.
