What is L-dopa good for?
l-dopa is used to treat the motor symptoms associated with Parkinson’s disease, a neurodegenerative movement disorder characterized by a loss of dopamine neurons. l-dopa is the precursor to dopamine and crosses the blood-brain barrier to increase dopamine neurotransmission.
Is L-dopa used today?
Five decades after its introduction, L-DOPA is still the most effective and widely used drug to alleviate the symptoms of PD (4). In recent years, deep brain stimulation (DBS) has become a standard evidence-based therapy for severe movement disorders such as PD (5), tremor (6) and dystonia (7).
Why is L-dopa famous?
Levodopa revolutionized the symptomatic treatment of Parkinson’s disease (PD). It is considered the most efficacious drug for PD as it consistently provides better symptom control.
How does L-dopa turn to dopamine?
L-DOPA is converted to dopamine by the aromatic amino-acid decarboxylase enzyme in the blood. This source of dopamine causes peripheral side effects like nausea and reduces the amount of L-DOPA available to cross into the brain.
Is L-dopa good for depression?
Levodopa (l-DOPA) and dopaminergic agonists have been shown to reduce the depressive symptoms (21, 22), to have no effects (23, 24), or to worsen the depression in PD patients (25–28).
Is L-DOPA safe to take?
As long as you take it, levodopa will remain beneficial. But, if the natural progression of your disease requires higher levodopa doses, side effects — including dyskinesia (irregular, involuntary, uncontrolled movement) — can occur.

Does L-DOPA affect mood?
In fact there is evidence that, coincident with motor fluctuations, chronic L-DOPA may promote the development of mood fluctuations, including alterations in euphoria, anxiety and depression (Maricle et al., 1995; Kulisevsky et al., 2007).
