Pharmacological properties
Pharmacodynamics
The mechanism of influence of the active substance Vinpocetine FORTE - Vinpocetine consists of the following factors: improvement of cerebral blood flow; activation of metabolism; beneficial effect on the rheological properties of blood.
The neuroprotective effect of vinpocetine is realized due to a decrease in the adverse cytotoxic effect of excitatory amino acids. As a result, blocking of Na + and Ca 2+ -channels and NMDA- and AMPA-receptors occurs. The substance selectively inhibits Ca 2+ -calmodulin-dependent-cGMP-phosphodiesterase. Increases the exchange of norepinephrine and serotonin in the brain, has an antioxidant effect, and stimulates the noradrenergic neurotransmitter system.
Improvement of microcirculation in the brain is carried out due to the following effects: inhibition of platelet aggregation and adenosine reuptake; an increase in the deformability of erythrocytes and a decrease in the pathologically increased blood viscosity.
Due to a decrease in the affinity of erythrocytes to vinpocetine, the drug promotes the transfer of oxygen into cells.
By inhibiting cerebral vascular resistance, vinpocetine selectively increases cerebral blood flow without significantly affecting systemic indicators of blood circulation, including blood pressure (blood pressure), heart rate (heart rate), cardiac output, and total peripheral vascular resistance.
The use of vinpocetine does not lead to the development of the stealing effect.
Pharmacokinetics
Vinpocetine after oral administration is rapidly absorbed in the gastrointestinal tract (absorption occurs mainly in the proximal small intestine). T Cmax (time to reach maximum concentration) in blood plasma - 60 minutes. In the process of passing through the intestinal wall, the substance is not metabolized.
After oral administration of radioactively labeled vinpocetine to rats, the highest radioactivity was observed in the gastrointestinal tract and liver. The maximum tissue level after administration was recorded after 2–4 hours. The concentration of the substance in the tissues of the brain did not exceed its content in the blood.
The connection with plasma proteins in humans is 66%, bioavailability is about 7%. V d (volume of distribution) - 246.7 ± 88.5 liters, which is evidence of a high binding to tissues. The total clearance is higher than the hepatic blood flow rate (66.7 and 50 L / h, respectively), thus indicating extrahepatic metabolism.
Vinpocetine easily penetrates the blood-brain barrier (including through the blood-brain barrier), as well as through the placental barrier and into breast milk (0.25% of the dose during the first hour).
The main metabolite of vinpocetine is AVA (apovincaminic acid), it accounts for 25 to 30% of the original compound. AUC (area under the concentration-time curve) of AVK after oral administration is 2 times higher than that of intravenous administration of the substance. This indicates that vinpocetine is subject to a pronounced effect of the first pass through the liver.
Other metabolites of vinpocetine: hydroxy-AVK, hydroxyvinpocetine, AVK-dioxyglycinate and their conjugates (glucuronides and / or sulfates).
Vinpocetine does not accumulate in the body, therefore, patients with impaired renal / hepatic function do not need to adjust the dosage regimen. Perhaps they will need a longer use of Vinpocetine FORTE.
With repeated use of 10 mg of vinpocetine, linear pharmacokinetics is manifested, the value of C ss (equilibrium plasma concentration) is 2.1 ± 0.33 ng / ml.
The substance is excreted unchanged slightly (a few percent). T 1/2 (half-life) is 4.83 ± 1.29 hours.
When conducting studies with radioactively labeled vinpocetine, it was found that excretion by the intestines and kidneys occurs in a ratio of 40 ÷ 60%. AVK is excreted by glomerular filtration.
In dogs and rats, high radioactivity after administration of a radioactively labeled substance was found in bile, however, significant enterohepatic recirculation was noted.
Vinpocetine is intended for the treatment of mainly elderly patients, therefore, the slowdown in distribution and metabolism, as well as excretion, noted in this age group, especially during a long course, should be taken into account.
According to the results of clinical studies, the pharmacokinetic processes of vinpocetine in elderly patients do not differ significantly from young patients, and the accumulation of the substance and its metabolites does not occur.

special instructions
In patients with an initially prolonged QT interval, as well as in the case of combined use with drugs that lead to an extension of the QT interval, during the period of taking Vinpocetine FORTE, electrocardiographic monitoring (ECG control) should be periodically performed.
In the case of severe cardiac arrhythmias, increased intracranial pressure, combination therapy with antiarrhythmic drugs, long QT syndrome or combination therapy with drugs that cause QT interval prolongation, Vinpocetine FORTE should be used with caution.
Influence on the ability to drive vehicles and complex mechanisms
Patients during the period of application of Vinpocetine FORTE should be careful when driving vehicles.
Application during pregnancy and lactation
Vinpocetine FORTE is not prescribed during pregnancy / lactation.
Vinpocetine crosses the histohematogenous placental barrier, but the concentration of the substance in the placenta and in the fetal blood is lower than in the blood of a pregnant woman. Teratogenic and embryotoxic effects were not identified. When conducting studies on animals with the use of high doses of the drug, the development of placental bleeding and spontaneous abortions, presumably associated with an increase in placental blood flow, was noted.
The concentration of vinpocetine in breast milk reaches 0.25% of the oral dose of the drug within an hour. The doctor, when deciding to cancel breastfeeding or refuse to take Vinpocetine FORTE, must balance the benefits for the child and the woman.
Pediatric use
Since there are no data from clinical studies, Vinpocetine FORTE is not prescribed for patients under 18 years of age.
Drug interactions
The antihypertensive effect of vinpocetine can be enhanced when combined with methyldopa, and therefore requires systematic monitoring of blood pressure.
There are no data confirming the development of interaction with centrally acting drugs, anticoagulants and antiarrhythmic drugs, however, when they are combined with Vinpocetine FORTE, care must be taken.
Analogs
Vinpocetine FORTE analogues are Vinpocetine, Vero-Vinpocetine, Vinpoton, Bravinton, Vincetin, Cavintazol, Telektol, Oxopotin, Korsavin, Cavinton, etc.
