Pharmacological properties
Pharmacodynamics
Citicoline stimulates the biosynthesis of structural phospholipids of neuronal membranes, which is confirmed by magnetic resonance spectroscopy. Due to this mechanism of action, citicoline improves the functioning of such membrane mechanisms as the work of ion exchange pumps and receptors, the modulation of which is necessary for the normal conduction of nerve impulses.
Due to its stabilizing effect on the neuronal membrane, citicoline exhibits anti-edema properties that help reduce brain edema.
Experimental studies have shown that citicoline inhibits the activation of some phospholipases (A1, A2, C, and D), reduces the formation of free radicals, prevents the destruction of membrane systems, and preserves antioxidant defense systems such as glutathione.
Citicoline preserves the energy reserves of neurons, inhibits apoptosis, and stimulates the synthesis of acetylcholine.
It has been experimentally proven that citicoline also exhibits a preventive neuroprotective effect in focal cerebral ischemia.
Clinical studies have shown that citicoline significantly increases functional recovery in patients with acute ischemic stroke, which coincides with a slowdown in the growth of ischemic brain damage volume according to neuroimaging data.
In patients with traumatic brain injury, citicoline accelerates recovery and reduces the duration and intensity of post-traumatic syndrome.
Citicoline improves the level of attention and consciousness, cognitive and neurological disorders associated with cerebral ischemia, and helps reduce the manifestations of amnesia.
Pharmacokinetics
After administration of the drug, a significant increase in the level of choline in the blood plasma is observed. The drug is metabolized in the intestines and liver to form choline and cytidine.
After administration, citicoline is widely distributed in brain structures with rapid incorporation of the choline fraction into structural phospholipids and the cytidine fraction into cytidine nucleotides and nucleic acids. In the brain, citicoline is incorporated into cellular, cytoplasmic and mitochondrial membranes, integrating into the structure of the phospholipid fraction.
Only a small amount of the dose is found in the urine and feces (less than 3%). Approximately 12% of the dose is excreted through exhaled CO2. During the excretion of the drug with urine, two phases are distinguished: the first phase - within 36 hours, in which the rate of excretion decreases rapidly, and the second phase - in which the rate of excretion decreases much more slowly. The same phasic nature is observed in excretion through the respiratory tract. The rate of CO2 excretion decreases rapidly, for about 15 hours, then decreases much more slowly.
Indication
Stroke, acute phase of cerebrovascular disorders, treatment of complications and consequences of cerebrovascular disorders. Traumatic brain injury and its neurological consequences. Cognitive and behavioral disorders due to chronic vascular and degenerative cerebral disorders.
Contraindication
Hypersensitivity to citicoline or other components of the drug. Increased tone of the parasympathetic nervous system.
Interaction with other medicinal products and other types of interactions
Citicoline enhances the effect of levodopa. It should not be administered simultaneously with drugs containing meclofenoxate.
Application features
In case of intravenous administration, the drug should be administered slowly (over
3-5 minutes depending on the dose administered).
In the case of intravenous drip administration, the infusion rate should be 40-60 drops per minute.
In case of persistent intracranial hemorrhage, the dose of 1000 mg per day and the rate of intravenous infusion (30 drops per minute) should not be exceeded.
Ability to influence reaction speed when driving vehicles or other mechanisms
In individual cases, some adverse reactions from the central nervous system may affect the ability to drive or operate complex machinery.
Use during pregnancy or breastfeeding
There are no adequate data on the use of citicoline in pregnant women. Data on the excretion of citicoline into breast milk and its effect on the fetus are unknown. During pregnancy or breastfeeding, the drug can be prescribed only if the expected therapeutic benefit to the mother outweighs the potential risk to the fetus.
Method of administration and doses
The drug is intended for intramuscular or intravenous use. Intravenously, the drug can be administered by slow injection (over 3-5 minutes depending on the dose administered) or drip (rate: 40-60 drops per minute).
The maximum daily dose is 2000 mg.
The duration of treatment depends on the course of the disease and is determined by the doctor.
Elderly patients do not require dose adjustment.
The solution for injection is intended for single use only. The drug should be used immediately after opening the ampoule. Any remaining drug should be discarded. The drug can be mixed with all isotonic intravenous solutions and hypertonic glucose solution.
If necessary, continue treatment with the drug in the form of a solution for oral administration.
Children
Experience with the use of the drug in children is limited.
Overdose
