Cytidine 5'-diphosphocholine, CDP-choline or citicoline, is an essential intermediate in the biosynthetic pathway of the structural phospholipids of cell membranes, especially in that of phosphatidylcholine. Upon oral or parenteral administration, CDP-choline releases its two principle components, cytidine and choline. When administered orally, it is(More)
Cytidine 5'-diphosphocholine, CDP-choline, or citicoline is an essential intermediate in the biosynthetic pathway of structural phospholipids in cell membranes, particularly phosphatidylcholine. Following administration by both the oral and parenteral routes, citicoline releases its two main components, cytidine and choline. Absorption by the oral route is(More)
BACKGROUND AND PURPOSE No single neuroprotective agent has been shown to influence outcome after acute stroke. Citicoline has been studied worldwide in many clinical trials with positive findings, but only 1 trial has obtained significant results in the primary efficacy variables. Our objective was to evaluate the effects of oral citicoline in patients with(More)
BACKGROUND AND PURPOSE Cytidine-5'-diphosphocholine (citicoline or CDP-choline), an intermediate in the biosynthesis of phosphatidylcholine, has shown beneficial effects in a number of CNS injury models including cerebral ischemia. Citicoline is the only neuroprotectant that has proved efficacy in patients with moderate to severe stroke. However, the(More)
Cytidine 5'-diphosphocholine (citicoline) is a an endogenous intermediate in the biosynthesis of structural membrane phospholipids and brain acetylcholine. Citicoline has been extensively used for the treatment of neurodegenerative disorders associated with head trauma, stroke, brain aging, cerebrovascular pathology and Alzheimer's disease. In this study we(More)
BACKGROUND Citicoline is approved in some countries for the treatment of acute ischaemic stroke. The drug has shown some evidence of efficacy in a pooled analysis. We sought to confirm the efficacy of citicoline in a larger trial. METHODS We undertook a randomised, placebo-controlled, sequential trial in patients with moderate-to-severe acute ischaemic(More)
Citicoline has been demonstrated to be beneficial in several models of cerebral ischaemia. We tested the hypothesis that citicoline may provide apoptotic pathways following focal cerebral ischaemia. Focal cerebral ischaemia was produced by distal, permanent middle cerebral artery occlusion (MCAO) in Sprague-Dawley rats. The animals were randomised into four(More)
Citicoline, or CDP-choline, is an essential endogenous intermediate in the biosynthesis of phosphatidylcholine that may act as a neuroprotector in several models of neurodegeneration. The present study analyses the effects of citicoline in the paradigm of staurosporine-induced cell death in human SH-SY5Y neuroblastoma cells. Citicoline reduces apoptosis(More)
Citicoline (CDP-choline or cytidine 5'-diphosphocholine) has been used as a therapeutic agent in combination with levodopa in the treatment of Parkinson's disease (PD). The present study examines the effects of citicoline by using validated in vivo and in vitro models. Citicoline reduces the cytotoxic effect of 6-hydroxydopamine (6-OHDA)-treated human(More)
