A phase I study to evaluate the effect of high-dose carbidopa on levodopa pharmacokinetics [PDF]

Frontiers in Pharmacology
Levodopa is the gold standard treatment for Parkinson’s disease. However, a high unmet medical need exists for longer-lasting oral levodopa formulations to achieve sustained motor improvement with reduced risk of the effect wearing off.

Levodopa influence on turning dynamics in people with Parkinson’s disease [PDF]

Scientific Reports
Turning behaviors are affected in people with Parkinson’s disease (PwPD) leading to falls and Freezing of Gait (FOG). Levodopa therapy is commonly recommended for PwPD to help alleviate motor symptoms.

Contribution of dopaminergic polymorphisms to levodopa treatment response and drug concentration in Chinese patients with Parkinson’s disease [PDF]

Clinical Parkinsonism & Related Disorders
Background: Levodopa is the mainstay of treatments for Parkinson’s disease (PD), but large heterogeneity exists in patient response. Pharmacogenetic studies highlighted that genetic factors may play a relevant influence in this drug response variability.

Levodopa-Induced Changes in Electromyographic Patterns in Patients with Advanced Parkinson’s Disease [PDF]

Frontiers in Neurology, 2018
Levodopa medication is the most efficient treatment for motor symptoms of Parkinson’s disease (PD). Levodopa significantly alleviates rigidity, rest tremor, and bradykinesia in PD.

Patient Selection in Deep Brain Stimulation: A Role for Transcranial Direct Current Stimulation to Enhance the Levodopa Challenge? [PDF]

Annals of Clinical and Translational Neurology
Dopaminergic medication and deep brain stimulation (DBS) improve motor symptoms in Parkinson's disease (PD), but levodopa response alone may not predict DBS outcomes.

Very-Low-Dose Levodopa Therapy for Pediatric Neurological Disorders: A Preliminary Questionnaire in Japan

Frontiers in Pediatrics, 2021
Introduction: Post-synaptic dopamine receptor supersensitivity (DARSS) has been extensively researched by Dr. Masaya Segawa, who has investigated the efficacy of very-low-dose levodopa therapy (VLDT; 0.5–1 mg/kg/day).

The pharmacokinetics of continuous subcutaneous levodopa/carbidopa infusion: Findings from the ND0612 clinical development program

Frontiers in Neurology, 2022
BackgroundWhile treatment with levodopa remains the cornerstone of Parkinson's disease (PD) management, chronic oral therapy is often associated with the development of motor complications, that correlate to fluctuating levodopa plasma concentrations ...

Levodopa responsive gait dynamics in OFF- and ONOFF-state freezing of gait in Parkinson’s disease

Clinical Parkinsonism & Related Disorders, 2023
Background: In people with Parkinson’s disease (PwPD), Freezing of Gait (FOG) episodes can be levodopa responsive (OFF-FOG) or levodopa unresponsive (ONOFF-FOG).

Riluzole Administration to Rats with Levodopa-Induced Dyskinesia Leads to Loss of DNA Methylation in Neuronal Genes

Cells, 2021
Dyskinesias are characterized by abnormal repetitive involuntary movements due to dysfunctional neuronal activity. Although levodopa-induced dyskinesia, characterized by tic-like abnormal involuntary movements, has no clinical treatment for Parkinson’s ...

Rapid drug increase and early onset of levodopa-induced dyskinesia in Parkinson's disease.

PLoS ONE, 2020
A higher levodopa dose is a strong risk factor for levodopa-induced dyskinesia (LID) in patients with Parkinson's disease (PD). However, levodopa dose can change during long-term medication.
