Pharmacological properties of Cytoflavin
Pharmacological effects of CYTOFLAVIN are governed by the combined action of the ingredients, constituting it.
CYTOFLAVIN improves coronary and cerebral blood flow; activates metabolic processes in central nervous system; promotes recovery of consciousness, reflex alterations, and paresthesia; improves intellectual and mental functions. It also greatly reduces postanesthetic arousal time in postanesthetic clouding of consciousness.
Metabolic drug. Pharmacological effects are due to the combined action of members of the drug Cytoflavin components. Stimulates cellular respiration and energy production, improves the process of utilization of oxygen by tissues, restores the activity of enzymes, providing an antioxidant effect.
Preparation activates intracellular protein synthesis, promotes utilization of glucose, fatty acids and GABA in neurons resynthesis shunt Roberts.
Has a positive effect on the brain bioelectrical activity.
Citoflavin improves cerebral and coronary blood flow, stimulates metabolic processes in the central nervous system, reduces reflex disorders, helps to restore impaired sensitivity and intellectual-mental functions of the brain.
Positive effect on the parameters of the neurological status: reduces the severity of asthenic, cephalgic, vestibular-cerebellar, cochleovestibular syndrome, as well as eliminates the disorder in the emotional-volitional sphere (reduces anxiety, depression). Improves cognitive function and mnemonic quality of life.
Administration of CYTOFLAVIN within 12 hours after onset of cerebral stroke has beneficial effect on ischemic and necrotic lesions (diminution of lesion focus), normalizes neurologic status and significantly reduces the rate of disability in a long-term perspective.
Pharmacological properties of Cytoflavin
Pharmacodynamics
Pharmacological effects are caused by the combined action of a part of the drug cytoflavin components.
Cytoflavin intensifies the aerobic glycolysis, leading to the activation of glucose utilization and fatty acid β-oxidation, and also stimulates the synthesis of γ-aminobutyric acid in neurons.
Cytoflavin increases the stability of the membranes of nerve and glial cells to ischemia, resulting in a decrease in the concentration of proteins neurospecifical characterizing the level of degradation of the main structural components of the nervous tissue.
Cytoflavin improves coronary and cerebral blood flow, activates metabolic processes in the central nervous system, restores impaired consciousness, promotes regression of neurological symptoms and improving cognitive functions of the brain. It has a rapid awakening effect in postanesthetic oppression of consciousness.
In applying the drug Cytoflavin in the first 12 hours after the onset of stroke observed beneficial for ischemic and necrotic processes in the affected area (reduction of the hearth), recovery of neurological status and reduction of disability in a remote period.
Pharmacokinetics
With intravenous infusion at a rate of about 2 ml / min (in terms of undiluted Cytoflavin) succinic acid and inosine are utilized almost instantly and are not detected in the blood plasma.
Succinic acid: peak concentration is determined within the first minute after administration to a further rapid decrease in cumulative and without returning it to the level of background values as a result of enzymatic breakdown to carbon dioxide and water. Inosine is metabolized in the liver to form inosine monophosphate, followed by its oxidation to uric acid. In small quantities excreted by the kidneys. Please pay attention to Renisamin.
Nicotinamide is rapidly distributed in all tissues, crosses the placenta and breast milk, is metabolized in the liver with the formation of N-methylnicotinamide, excreted by the kidneys. plasma half-life period of about 1.3 hours, the equilibrium distribution of volume - about 60 liters, total clearance - about 0.6 L / min.
Riboflavin is unevenly distributed: the highest number in the myocardium, liver and kidneys. plasma half-life period of about 2 hours and the equilibrium distribution of volume - about 40 liters, total clearance - about 0.3 L / min. It penetrates through the placenta and breast milk. Communication with plasma proteins - 60%. Excreted by the kidneys, partly in the form of metabolites; in high doses - preferably in an unmodified form.
Indications for Cytoflavin
In adults in the treatment of:
- Cerebral infarction;
- The effects of cerebrovascular disease (cerebral infarction, cerebral atherosclerosis);
- Toxic and hypoxic encephalopathy in acute and chronic poisoning, endotoxemia, postanesthetic oppression of consciousness, as well as for the prevention and treatment of hypoxic encephalopathy during cardiac surgery with cardiopulmonary bypass.
In children (including preterm gestation 28-36 weeks) in combination therapy in the neonatal period:
- Cerebral ischaemia.
Contraindications for Cytoflavin
Hypersensitivity of the components of the drug, pregnancy, lactation.
Not assigned patients (except for the neonatal period), are in critical condition, to stabilize the central hemodynamics and / or reducing the partial pressure of oxygen in arterial blood below 60 mm Hg. Art.
Carefully
When nephrolithiasis, gout, hyperuricemia. If you have one of these diseases, before taking Cytoflavin medication should consult a physician.
Cytoflavin - Dosage and Administration
adults
Cytoflavin used only intravenously at a dilution of 100-200 ml of 5-10% dextrose or 0.9% sodium chloride solution. The speed of 4.3 ml / min.
1. When the brain infarct drug administered as early as possible from the onset of the disease in a volume of 10 ml for administration at intervals of 8-12 hours within 10 Dnei.pri severe form of the disease course of a single dose is increased to 20 ml.
2. If the consequences of cerebrovascular diseases (cerebral infarction, cerebral arteriosclerosis) the drug is administered in a volume of 10 ml per administration once daily for 10 days.
3. hypoxic encephalopathy and toxic drug is administered in a volume of 10 ml for administration twice a day every 8-12 hours for 5 days. In a coma - in the amount of 20 ml for an introduction to the dilution to 200 ml of dextrose solution. When postanesthetic oppression of consciousness - once in the same doses. In the treatment of hypoxic encephalopathy with cardiac surgery with cardiopulmonary bypass is administered 20 ml of the drug dilution in 200 ml of 5% dextrose solution for 3 days prior to surgery, the day of the operation, within 3 days after surgery.
In children (including premature) in the neonatal period with cerebral ischemia Cytoflavin daily dose of drug was 2 ml / kg. The calculated daily dose administered intravenously (slowly) after dilution in 5% or 10% dextrose solution (in a ratio of at least 1: 5). Time first introduction - the first 12 hours after birth; the optimal time to begin therapy are the first 2 hours of life. Recommended prepared solution administered by an infusion pump at a rate of 1 to 4 ml / hr, ensuring uniform delivery of the drug into the blood stream throughout the day, depending on the calculated volume daily solutions basic therapy, the patient's hemodynamic status indicators and acid-base status. The course of treatment an average of 5 days.
