Jejunal Infusion of Levodopa–Carbidopa Intestinal Gel Versus Oral Administration of Levodopa–Carbidopa Tablets in Japanese Subjects with Advanced Parkinson’s Disease: Pharmacokinetics and Pilot Efficacy and Safety
BACKGROUND AND OBJECTIVE Oral levodopa-carbidopa (LC-oral) treatment in advanced Parkinson's disease (PD) is associated with motor complications due to large fluctuations in levodopa plasma concentrations. Levodopa-carbidopa intestinal gel (LCIG) provides individualized continuous levodopa-carbidopa delivery through intrajejunal infusion. This study evaluated the pharmacokinetics, safety, and e...
متن کاملLevodopa-Carbidopa Intestinal Gel Pharmacokinetics: Lower Variability than Oral Levodopa-Carbidopa
In a double-blind, double-dummy, double-titration Phase 3 trial in advanced Parkinson's disease (PD) patients, the efficacy and safety of Levodopa-carbidopa intestinal gel (LCIG) infusion were characterized relative to immediate-release oral levodopa-carbidopa (LC-oral) treatment. We present in this report the comparative pharmacokinetic profiles of LCIG and LC-oral from this pivotal study. The...
متن کاملLevodopa-carbidopa intestinal gel for treatment of advanced Parkinson's disease.
BACKGROUND Levodopa is the mainstay of Parkinson's disease (PD) treatment, but is often eventually associated with disabling motor complications in patients with advanced PD. The inability of perorally administered levodopa to provide more physiologic continuous dopaminergic stimulation (CDS) is a leading hypothesis to explain these complications. OBJECTIVE To investigate the cumulative effic...
متن کاملPopulation pharmacokinetics of levodopa in subjects with advanced Parkinson's disease: levodopa-carbidopa intestinal gel infusion vs. oral tablets
AIMS Levodopa-carbidopa intestinal gel (LCIG) provides continuous levodopa-carbidopa delivery through intrajejunal infusion. This study characterized the population pharmacokinetics of levodopa following a 16 h jejunal infusion of LCIG or frequent oral administration of levodopa-carbidopa tablets (LC-oral) in subjects with advanced Parkinson's disease (PD). METHODS A non-linear mixed-effects ...
متن کاملEffects of levodopa/carbidopa intestinal gel versus oral levodopa/carbidopa on B vitamin levels and neuropathy
OBJECTIVES To determine the possible interactions between levodopa therapy and plasma levels of B vitamins in patients with advanced idiopathic Parkinson's disease (IPD) in the context of either oral levodopa therapy or levodopa/carbidopa intestinal gel (LCIG). Secondly, to determine the prevalence of neuropathy and its relation to plasma levels of B vitamins and homocysteine. METHODS Medicat...
