Iron & ferroptosis Levodopa formulations
-
Levodopa may increase iron accumulation in the substantia nigra, potentially amplifying the ferroptotic and oxidative stress that underlies dopaminergic neuron loss in Parkinson's disease.
Title of preprint: 'Levodopa increases substantia nigra iron: implications for Parkinson's disease.' Related published literature notes that levodopa and its downstream products can generate reactive oxygen species and that iron–levodopa interactions may alter iron deposition and transport in nigral neurons.
