Focusing on levodopa (L-dopa), the primary treatment for Parkinson's disease, they identified which bacteria out of the trillions of species is responsible for degrading the drug and how to stop this microbial interference.
SLS-006 has shown efficacy in early-stage Parkinson's disease patients as a monotherapy and as a potential adjunctive therapy in late-stage Parkinson's disease patients upon co-administration with a low dosage of L-Dopa.
Objective: To assess effects of levodopa (L-dopa) on personality disturbances and dysexecutive symptoms in patients with idiopathic Parkinson's disease (PD).
Objectives: To determine (i) levodopa (L-Dopa) responsiveness on cortical functions, health related quality of life and fatigue severity (ii) relationship between cortical functions, health related quality of life and fatigue severity post L-Dopa treatment of patients with idiopathic Parkinson's Disease (I-PD).
Due to this loss, exogeneous L-dopa cannot be metabolized properly leading to non-physiological dopamine release and LID eventually.
It was designed to deliver a precise dose of a dry powder formulation of L-dopa to the lung.
A similar study but with a different objective was conducted by Ferrarin et al.; they used a marker-based system to examine the effects of subthalamic stimulation on gait kinematics and kinetics in PD, and they were able to find clinical differences in the effects produced by medication (L-dopa) and DBS [12].
Baker (Phillipsburg, NJ, USA), ferulic acid was from ChromaDEX (Irvine, California), gallic acid was from Alfa Aesar (Ward Hill, MA, USA), kojic acid and (s)-2-amino-3-(3,4-dihydroxyphenyl) propanoic acid (L-dopa) were from Acros (New Jersey, USA), and methyl paraben was from Supelco (Bellefonte, USA).
As most patients in these studies were treated with a combination of L-DOPA and carbidopa, it is possible that one or both of these drugs could exhibit anti-cancer properties and contribute to the lower incidence of cancer observed in these patients.
Sudden discontinuation of L-Dopa, which has a short half-life, can cause muscle rigidity, difficulty in spontaneous respiration, and requirement of mechanical ventilation (1).
Background: Parkinson's disease (PD) patients with long-term levodopa (L-DOPA) treatment are suffering from severe circadian dysfunction.
