Mechanism of action

Levodopa (L-DOPA) is a precursor to dopamine that crosses the blood-brain barrier, unlike dopamine itself. Once in the brain, it is converted to dopamine by the enzyme aromatic amino acid decarboxylase (AADC), restoring dopamine neurotransmission in the basal ganglia. The infusion formulation provides continuous delivery to maintain stable dopamine levels and reduce motor fluctuations in advanced Parkinson's disease.
