standard PPH treatment package will require action on many fronts and engagement of multiple stakeholders across system levels , including policymakers, national and subnational ministry of health managers, professional societies, facility managers, facility health care workers, community leaders , health agents, and women and families. The possibility should be considered and tested that, in spite of apparently fast catabolism, the intact citicoline molecule or the phosphorylated intermediate products of its hydrolysis, cytidine monophosphate and phosphocholine, are pharmacologically active. Patients are recommended to continue taking citicoline at subsequent stages of rehabilitation for 6 months — 1 year after strokeas it makes an additional contribution to improving their cognitive functions. However, the most promising interventions intensifying the neurorecovery in the subacute stage of stroke are granulocyte colony-stimulating factor (G-CSF), citicoline and cell therapy .
This classification paradigm also appeared in one of our previous papers, dedicated to neuroprotection in spinal cord injury (SCI), published in 2009, the October issue of Spinal Cord journal. 1.3 Citicoline mechanism of action From the data available in the literature, it is known that the exogenous administration of citicoline causes an increase in endogenous phosphatidylcholine synthesis and thus accelerates the repair of the previously damaged cell membranes (Secades 2001).

Pharmacology and mechanism of action Citicoline is a water-soluble compound which archives greater than 90-percent bioavailability. As a medicine, it is taken by mouth as a supplement or given as an injection into the vein (by IV) or as a shot into the muscle. We examined the effect of the neuroprotective and neuroreparative agent citicoline on the growth of cerebral ischemic lesions in a double‐blind placebo‐controlled study involving patients with acute ischemic stroke using diffusion‐weighted magnetic resonance imaging (DWI). We agree with Dr Grieb that the mechanisms of action are not completely understood.
A number of studies have shown that citicoline’s bioavailability is very good following oral administration. Dietary factors such as methionine, betaine, myo-inositol, folic acid and vitamin B12 or the combination of different levels and composition of fat, carbohydrate and protein in the diet, as well as the age, sex, caloric intake and growth rate of animals, all have influence on the lipotropic action of choline and thus the requirement of this nutrient (Mookerjea, 1971; DuCoa L.P., 1994). Studies have shown that citicoline is effective and safe in the treatment of ischemic stroke in the acute and subacute period, and this treatment usually begins within the first 24 hours after stroke onset and lasts for at least 6 weeks. Administration of citicoline decreased cognitive impair-ment, cerebral edema, neuronal loss, and cortical contusion and improved neurological recovery in adult rat models of TBI [15–16]. The idea of adding citicoline to topical treatment of primary open angle glaucoma (POAG) aimed at decreasing intraocular pressure (IOP) appeared as a logical consequence of accepting neurodegenerative character of this disease. Methods: All published papers containing experimental or clinical studies about the effects of Citicoline on RGCs morphology and function were reviewed. In an in-vitro study, Citicoline at high concentrations stimulated brain acetylcholinesterase (AChE).
Citicoline is used for Alzheimer's disease and other types of dementia, head trauma, cerebrovascular disease such as stroke, age-related memory loss, Parkinson's disease, attention deficit-hyperactive disorder (), and glaucoma. Although the precise mechanisms of this neuroprotective effect remain unclear, this combination may be useful in future treatment for acute stroke. This means that a decision concering data protection will not be taken before the election to the European Parliament in the fall of 2014. In dimeric silicon dioxide there are two oxygen atoms bridging between the silicon atoms with an Si-O-Si angle of 94° and bond length of 164.6 pm and the terminal Si-O bond length is 150.2 pm.
A 2015 study on adolescent males found that citicoline improved attention and psychomotor speed (grace, speed, skill in physical tasks), and reduced impulsivity compared to placebo. When the availability of choline is low or the need for acetylcholine increases, phospholipids containing choline can be catabolized from neuronal membranes. Therefore, the present study was conducted to find out the effectiveness of the addition of citicoline to patching in the treatment of amblyopia, in the age group of four to thirteen years. Citicoline enters the metabolic pathway of phosphatidylcholine production in the CNS How Citicoline Works: The primary mechanism of action for Citicoline is as a source of Choline. Citicoline is an intermediate in phosphotidylcholine synthesis, essential for membrane integrity and repair. 102,135 However, microglia that clear hemin have protective mechanisms that prevent cell death.
1994 demonstrated that chronic treatment of GPC of 200mg was able to partially restore muscarinic receptor density to levels of youth ages in both the hippocampus and striatum. Experimental studies in rats found evidence that Citicoline potentiates dopamine release in the brain, presumably by stimulating release of acetylcholine. Citicoline and homotaurine are renowned compounds that exhibit potent neuroprotective activities through distinct molecular mechanisms. The effect of citicoline on visual function has been studied in patients with glaucoma. The pathogenetic mechanisms leading to neuronal damage in acute disorders such as stroke, traumatic brain and spinal cord injuries, and neurodegenerative diseases are similar [1, 2]. Drug interactions, dosage, and pregnancy and breastfeeding safety information are provided.

Interestingly,‘priming’ of patients with citicoline following transient ischaemic attack (TIA) or minor stroke has not been considered as yet and also, since the mechanism of its action is not fully elucidated, optimal application cannot be determined accurately. Aims: To study the neuroprotective effect of oral citicoline (CT) therapy in primary open-angle glaucoma (POAG).Methods: This study included one eye each of 60 POAG patients.
116,117 The drug was well tolerated in human studies without any known adverse effects. The mechanisms of action for Oligonol® include support for healthy insulin function, adiponectin synthesis and lipolysis. The hypothesized mechanism of action assumes that citicoline undergoes hydrolysis and dephosphorylation to yield cytidine and choline products. Citicoline's mechanism of action is thought to entail cerebrovascular (blood circulation of the brain) regulation and neuroimmune (immune function of the nervous system) actions in the brain. Perhaps you have been using an acetylcholine agonist such as Piracetam to stimulate the release of acetylcholine, but you realize your body stores of this vital neurotransmitter are too low to meet your brain’s demands.

Your body makes citicoline from the essential, water-soluble nutrient choline.
Minor transient mechanixm effects are rare and most commonly include stomach pain and diarrhea. Mechanisms of Action When citicoline is taken orally, it is absorbed rapidly and becomes a choline donor that can increase neurotransmitter levels and has a . Retinol Vitamin A B vitamins: Probably role of citicoline in stroke rehabilitation: Minor transient adverse effects are rare and most commonly include stomach pain and diarrhea. Exogenous citicoline, thus, helps preserve the structural and functional integrity of the neuronal membrane. Choline is a nutrient similar to the B Vitamins that is necessary for the brain to be able to make the acetylcholine neurotransmitter. The therapeutic action of citicoline is thought to be caused by stimulation of PtdCho synthesis in the injured brain, although the experimental evidence for this is limited. However, its mechanism of action and clinical effectiveness must be further investigated. Effects on cognitive performance, brain bioelectrical activity and cerebral perfusion.
For some experiments, 100 μM citicoline (BIOMOL Research Laboratories, Inc.) was applied to the cells for 24 h before infection. Patients were randomly divided into two groups (A and B) of 30 participants each. mechanisms have been proposed, such as her - pes simplex type-1 , nerve compression , autoimmunity . The treatment (citicoline or vehicle) was topically administered twice daily for 15 days. Mechanisms of Action: In the simplest terms, Alpha GPC overall increases the choline saturation levels in the brain thereby promoting the upkeep of cell membranes. The aim of this study was to evaluate the cerebrovascular hemodynamic status in patients with ischemic stroke treated with citicoline compared with the control group.
Although citicoline has no confirmed benefits, its action mechanisms suggest that it would exert a neuroprotective effect in situations of hypoxia and ischaemia, and also favour resolution of cerebral oedema. Citicoline improved the outcome in several phase‐III clinical trials of stroke, but provided inconclusive results in recent clinical trials. Relevant therapies contain-ing antiviral medicine , corticosteroids , surgery in complementary and alternative medicine  and acupuncture treatment  are commonly applied to Bell’s palsy patients. The therapeutic action of citicoline is thought to be due to stimulation of phosphatidyl-choline (PtdCho) synthesis in the injured brain, though evidence is unclear . total citicoline dose crosses the blood-brain barrier as choline and cytidine, the utilization of these precursors in brain tissue for phospholipid biosynthesis is extremely efficient.4 Mechanism of Action Citicoline has several important mechanisms of action leading to a broad range of beneficial effects on neurological function.
