La levodopa (L-DOPA, L-3,4 dihidroxifenilalanina), también conocido como L-DOPA, el precursor metabólico de la dopamina, es el medicamento aislado más eficaz en el tratamiento de la enfermedad de Parkinson; los efectos terapéuticos y adversos de la levodopa resultan de su descarboxilación en dopamina por medio de la enzima descarboxilasa. La L-DOPA, o levodopa, è un amminoacido intermedio nella via biosintetica della dopamina.In clinica medica è utilizzata per il trattamento della malattia di Parkinson e di alcuni parkinsonismi per controllare i sintomi bradicinetici evidenti nella malattia ed è il farmaco più efficace per migliorare la qualità della vita nei pazienti con malattia di Parkinson idiopatica.
