Also known as L-Dopa which is an amino acid that acts as a precursor for neurotransmitters catecholamines (dopamine, norepinephrine, and epinephrine). Levodopa is used in the treatment of Parkinson's disease and dopamine-responsive dystonia. Reference standards of Levodopa API,and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below.
