Pharmacological action
Cavinton – a drug that improves cerebral circulation, cerebral metabolism and rheological properties of blood.
Has a cerebroprotective effect.
Reduces the severity of damaging cytotoxic reactions caused by stimulating amino acids and inhibits the functional activity of both transmembrane sodium and calcium channels, as well as NMDA and AMPA receptors. Potentiates the neuroprotective effect of adenosine. Stimulates brain metabolism, enhances the absorption and absorption of glucose and oxygen by the brain. Stimulates glucose transport through the BBB, shifts glucose metabolism to an energetically more beneficial aerobic direction. Selectively inhibits Ca2 + -calmodulin-dependent cGMP-phosphodiesterase, increases the concentration of cAMP and cGMP in the brain tissue, as well as the concentration of ATP and the ratio of ATP / AMP. Stimulates cerebral metabolism of norepinephrine and serotonin, stimulates the ascending noradrenergic system, has an antioxidant effect.
The drug selectively enhances cerebral blood flow: increases the cerebral fraction of the minute volume decreases the resistance of the cerebral vessels, without affecting the parameters of the general blood circulation (blood pressure, minute volume, heart rate, heart rate).
Does not cause the robbery phenomenon, on the contrary, with its use, the blood supply to the ischemic, but still viable area with low perfusion increases, the phenomenon of reverse robbery.
Improves the tolerance of hypoxia by brain cells, promoting the transport of oxygen to tissues due to a decrease in the affinity of red blood cells for it.
The drug improves microcirculation of the brain, inhibits platelet aggregation, reduces pathologically increased blood viscosity, increases the deformability of red blood cells and blocks their absorption of adenosine.
Indications
In neurology, acute and chronic cerebrovascular insufficiency (transient ischemia, progressive stroke, post-stroke conditions, vascular dementia, cerebral arteriosclerosis, post-traumatic and hypertensive encephalopathy, neuro-cerebrospinal neuropsychiatric insufficiency) (including memory impairment, dizziness, headache, aphasia, apraxia, motor disorders).
In ophthalmology – vascular diseases of the eye (atherosclerosis, angiospasm of the choroid and retina, degenerative diseases of the choroid, retina or macula, arterial and venous thrombosis or embolism, secondary glaucoma).
In ENT practice – hearing loss (vascular, toxic or age-related), Meniere’s disease, cochleovestibular neuritis, tinnitus, dizziness (labyrinth origin), vasovegetative manifestations of menopause syndrome.
Contraindications
Pregnancy lactation severe forms of heart failure and cardiac arrhythmias hypersensitivity to vinpocetine or other components of the drug.
Special instructions
Cavinton does not have hepato- and nephrotoxic effects, therefore, when prescribing the drug to patients with liver and kidney diseases, a dosage regimen is not required.
Use in pediatrics
Do not recommend prescribing the drug to children under the age of 18 due to a lack of experience with Cavinton in this category of patients.
