Citicoline is a choline donor involved in the biosynthesis of brain phospholipids and acetylcholine extensively used in the treatment of neurodegenerative diseases. In this study we investigated the effects of the oral administration of citicoline alone (C1000:1000 mg/day; C500:500 mg/day) or in combination with nimodipine (C +NI:300 + 90 mg/day) during 4 weeks on memory performance in elderly ...

In the present study, the efficacy of citicoline in alleviating the ischemia/reperfusion neuronal injury was investigated in male Sprague Dawley rats. Citicoline was administered before inducing ischemia, during ischemia and after reperfusion. Animals were scored for neurological deficits, assessed for anxiety, cognition and motor activity. Sodium potassium ATPase, Glutamate, ATP, NAD was deter...

BACKGROUND AND PURPOSE The neuroprotective potential of citicoline in acute ischemic stroke has been shown in many experimental studies and, although the exact mechanisms are still unknown, a clinical Phase III trial is currently underway. Our present study was designed to check whether citicoline also enhances neuroregeneration after experimental stroke. METHODS Forty Wistar rats were subjec...

Introduction Citicoline is a complex organic molecule that functions as an intermediate in the biosynthesis of cell membrane phospholipids. Citicoline is also known as CDP-choline and cytidine diphosphate choline (cytidine 5’-diphosphocholine). CDP-choline belongs to the group of biomolecules in living systems known as “nucleotides” that play important roles in cellular metabolism. CDP-choline ...

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 virtually complete, and bioavailabilit...

BACKGROUND AND PURPOSE We sought to evaluate the effects of the combination of cytidine-5'-diphosphocholine (citicoline) and thrombolysis on infarct size, clinical outcome, and mortality in a rat embolic stroke model. METHODS Eighty-three Sprague-Dawley rats were embolized in the carotid territory with a single fibrin embolus and randomly assigned to the following treatment groups: (1) contro...

Cytidine-5'-diphosphocholine (citicoline or CDP-choline), an intermediate in the biosynthesis of phosphatidylcholine (PtdCho), has shown beneficial effects in a number of CNS injury models and pathological conditions of the brain. Citicoline improved the outcome in several phase-III clinical trials of stroke, but provided inconclusive results in recent clinical trials. The therapeutic action of...

Phospholipid degradation is an important promoter of neuronal death after transient cerebral ischemia. Phospholipid hydrolysis by phospholipase A2 (PLA2) after transient cerebral ischemia releases arachidonic acid. Arachidonic acid metabolism results in formation of reactive oxygen species, lipid peroxides, and toxic aldehydes (malondialdehyde, 4-hydroxynonenal, and acrolein). Citicoline (cytid...

Citicoline (CDP-choline) has undergone 13 phase III clinical stroke trials, and is being evaluated for treatment of Alzheimer’s and Parkinson’s diseases. Phospholipid degradation and generation of reactive oxygen species (ROS) are major factors causing neuronal injury in CNS trauma and neurodegenerative diseases. Oxidative metabolism of arachidonic acid, which is released by the action of phosp...

BACKGROUND Citicoline is a drug approved for the treatment of acute ischemic stroke. Although evidence of its efficacy has been reported, recently published results of a large placebo-controlled clinical trial did not show differences. This study aims to assess whether starting citicoline treatment within 14 days after stroke onset improves the outcome in patients with acute ischemic stroke, as...
