Description
Levodopa (L-DOPA) is an endogenous precursor to dopamine, norepinephrine, and epinephrine; it can also be found in bean plants such as species of Mucuna. L-DOPA increases brain dopamine concentrations and is clinically used to treat symptoms of Parkinson’s disease. Peripheral increases in dopamine cause many side effects, including dyskinesias, hypotension, and nausea.
