Randomized Controlled Trial Multicenter Study
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.
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 efficacy of LCIG relative to LC-oral in Japanese subjects with advanced PD. ⋯ In Japanese subjects with advanced PD, LCIG resulted in an improved pharmacokinetic profile that appeared to be associated with reduced motor complications compared with LC-oral. These results extend previous findings in mainly Caucasian populations.
