The primary treatment for Parkinson's disease is dopaminergic stimulation. Although levodopa has historically been administered orally, maintaining a predictable plasma concentration of the drug is challenging. As a result, enteral administration of carbidopa/levodopa (Duopa) has emerged as a promising tool in the treatment of the disease. This requires placement of an enteric catheter, two of which have been approved by the Food and Drug Administration for delivery of Duopa. The approved tubes are placed using the "peroral" or "pull" technique, a method traditionally requiring endoscopy...

Carbidopa/levodopa enteral suspension (CLES; Duopa) is a suspension or gel formulation of carbidopa/levodopa that is approved by the USA Food and Drug Administration for the treatment of advanced Parkinson's disease patients with motor fluctuations. CLES is delivered at a constant rate continuously throughout the day into the jejunum through an infusion pump via a PEG-J tube implanted surgically. The efficacy of CLES was established in the USA based on a randomized, double-blind, double-dummy, active controlled, parallel group and 12-week study, in which mean daily OFF time was reduced by 4...

INTRODUCTION: The search for consistent, effective treatments in Parkinson's disease (PD) is ongoing. The importance of continuous dopaminergic stimulation (CDS) is understood to underlie best medical therapy for PD by providing closer replication of physiological patterns of dopamine release in healthy brains. AREAS COVERED: An overview of interventions to improve motor fluctuations in PD is presented. Significant improvements in off-time are achieved by providing continuous therapy using targeted deep brain stimulation (DBS), subcutaneous apomorphine infusion and carbidopa/levodopa enteral suspension (Duopa)...

Search Tips

Use Boolean operators: AND/OR

diabetic AND foot
diabetes OR diabetic

Exclude a word using the 'minus' sign

Virchow -triad

Use Parentheses

water AND (cup OR glass)

Add an asterisk (*) at end of a word to include word stems

Neuro* will search for Neurology, Neuroscientist, Neurological, and so on

Use quotes to search for an exact phrase

"primary prevention of cancer"
(heart or cardiac or cardio*) AND arrest -"American Heart Association"
