6.1 / Brief resume of the intended work:
Need for the study:
Worldwide, stroke is the second leading cause of death, responsible for 4.4 million of the 50.5 million deaths each year. Citicoline has been investigated as a therapy in stroke patient1.
Citicoline is a complex molecule that functions as an intermediate in the biosynthesis of cell membrane phospholipids. Citicoline is also known as CDP-choline and cytidinediphosphatecholine (cytidine 5’-diphosphocholine). CDP-choline belongs to the group of biomolecules in living systems known as ‘nucleotides’ that play important role in cellular metabolism. CDP-choline is composed of ribose, pyrophosphate, cytosine (a nitrogenous base) and choline. Exogenous Citicoline research in animal experiments and human clinical trials provides evidence of its cholinergic and neuroprotective actions.
As a dietary supplement (energy drinks), Citicoline appears useful for improving both the structural integrity and functionality of the neuronal membrane that may assist in membrane repair. Animal and clinical studies indicate the potential of Citicoline to improve cognitive deficits, stroke rehabilitation, brain and spinal cord injuries, neurological diseases, age - related memory problem and eye conditions2.Sodium salt of Citicoline is available in the market in the form of tablets and injections.
There is no analytical method reported in journals to estimate Citicoline in pharmaceutical dosage form. Hence, there is need to develop simple, accurate, precise, sensitive analytical method for Citicoline in different dosage form.

Chemically Citicoline is,
5'-O-[hydroxy({hydroxy[2-(trimethylammonio)ethoxy] phosphoryl}oxy)phosphoryl]cytidine3.
Molecular formula- C14H27N4O11P2+3, Molecular weight- 489.332 g/mol3
Solubility-Predicted water solubility 1000mg/ml at 25˚C and insoluble in ethanol4.
Chemical structure of Citicoline is3,

Richard J. Wurtman et al. worked on effect of oral CDP-Choline on plasma choline and uridine levels in humans. Plasma samples were deproteinized with methanol and fatty components were extracted into chloroform: methanol. A portion of the aqueous layer was lyophilized for subsequent HPLC analysis. Then the residue was redissolved in water, filtered and analysed by HPLC 5.
Mirakor V.A. et al. developed rapid and sensitive high performance liquid chromatography method for Citicoline in dosage form using C18 column and 50mM potassium dihydrogen orthophosphate : methanol (98:2) as mobile phase at a flow rate of 1ml/min, UV detection was made at 266nm6 .
Ed X. Wu et al. performed on proton magnetic resonance spectroscopy that revealed choline reduction in the visual cortex in an experimental model of chronic glaucoma by using cytidine 5’-diphosphocholine (CDP-choline, or citicoline), which is an intermediate in the generation of phosphatidylcholine (PtdCho) and acetylcholine (ACh) from choline (Cho), may improve visual cortical responses in glaucoma. Proton magnetic resonance spectroscopy has been increasingly utilized to investigate the metabolite distribution in selected volumes of the brain7.
Peter M.H. Heegaard et al. had developed a robust quantitative solid phase immunoassay for the acute phase protein C-reactive protein (CRP) based on cytidine 5’-diphosphocholine coupled dendrimers. The present paper described a robust and sensitive ELISA for CRP, based on the affinity of CRP for phosphocholine. In this design synthetic globular polymers (dendrimers) were used as scaffolds for the multivalent display of phosphocholine molecules8.
Objectives of the study:
Literature review reveals that tremendous work has been done in pharmacological area butthere is hardly work found on analytical method development of Citicoline in bulk and pharmaceutical formulations.
The objectives of present work are,
  1. To develop analytical method for Citicoline by UV-Visible spectrophotometer.
  2. To develop HPLC method to estimate Citicoline in bulk and pharmaceutical formulation.
  3. To validate developed analytical methods as per ICH guidelines.
