Pharmacological Properties.

Pharmacodynamics.

Citicoline stimulates the biosynthesis of structural phospholipids in neuronal membranes, as confirmed by magnetic resonance spectroscopy data. Citicoline improves the functioning of membrane mechanisms such as ion pumps and receptors, the regulation of which is essential for normal nerve impulse conduction. Due to its stabilizing effect on neuronal membranes, citicoline exhibits anti-edematous properties that promote reabsorption of cerebral edema.

Clinical studies have shown that citicoline inhibits the activation of certain phospholipases (A1, A2, C, and D), thereby reducing the formation of free radicals, preventing the destruction of membrane systems, and preserving antioxidant defense systems such as glutathione.

Citicoline preserves neuronal energy reserves and inhibits apoptosis, thereby enhancing cholinergic transmission.

Experimental evidence has demonstrated that citicoline also exerts a preventive neuroprotective effect in focal cerebral ischemia.

Clinical studies have shown that citicoline significantly improves functional recovery rates in patients with acute cerebrovascular disorders, which correlates with slowing the progression of ischemic brain lesions as observed in neuroimaging. In patients with traumatic brain injury, citicoline accelerates recovery and reduces the duration and severity of post-traumatic syndrome.

Citicoline improves levels of attention and consciousness and helps reduce symptoms of amnesia, cognitive deficits, and other neurological disorders associated with cerebral ischemia.

Pharmacokinetics.

Citicoline is well absorbed after oral, intramuscular, and intravenous administration. Plasma choline levels increase significantly following administration by these routes. Oral absorption is practically complete, and bioavailability is nearly equivalent to that achieved with intravenous administration.

Depending on the route of administration, the drug is metabolized in the intestine and liver into choline and cytidine. After administration, citicoline is widely distributed into brain structures, with rapid incorporation of the choline fraction into structural phospholipids and the cytidine fraction into cytidine nucleotides and nucleic acids. Upon reaching the brain, citicoline integrates into cellular, cytoplasmic, and mitochondrial membranes, participating in the formation of phospholipid fractions.

Only a small amount of the dose is excreted in urine and feces (less than 3%). Approximately 12% of the dose is excreted as exhaled CO₂. The elimination of the drug in urine occurs in two phases: the first phase lasts approximately 36 hours, during which the elimination rate rapidly decreases, and the second phase, in which the elimination rate declines much more slowly. A similar biphasic pattern is observed in CO₂ excretion: the rate of CO₂ elimination rapidly decreases after approximately 15 hours, then declines much more slowly thereafter.

Use during pregnancy or breastfeeding.

There is insufficient data on the use of Lyrica® in pregnant women.

There are no data available on the excretion of citicoline in breast milk or its effects on the fetus. During pregnancy or breastfeeding, the product should be prescribed only when the expected benefit to the mother outweighs the potential risk to the fetus.

Ability to influence reaction speed when driving or operating machinery. In individual cases, certain adverse reactions from the central nervous system may affect the ability to drive or operate complex machinery.
