Pyriditol differs in structure from nootropic preparations of GABAergic nature. It can be considered as a doubled pyridoxine molecule (see), containing a disulfide "bridge" (pyridoxine disulfide).
Pharmacologically, the drug is characterized by nootropic activity with a complex spectrum of psychotropic activity. It enhances the effects of phenamine, while reducing spontaneous locomotor activity, prolongs the hypnotic effect of barbiturates, and enhances the anticonvulsant effect of phenobarbital. The drug activates metabolic processes in the central nervous system, helps to accelerate the penetration of glucose through the blood-brain barrier, reduces the excessive formation of lactic acid, increases the resistance of brain tissue to hypoxia. There is evidence of a decrease in the content of GABA in the nervous tissue under the influence of pyriditol. In 6-vitamin activity does not possess.
According to the clinical effects, pyriditol is similar to antidepressants with sedative properties, but in terms of the combination of actions it is classified as nootropic drugs.
Pyriditol is used for complex therapy for shallow depression with lethargy in asthenic conditions, adynamia, neurosis-like disorders, traumatic and vascular encephalopathy, residual effects after neuroinfection and cerebrovascular accident, cerebral atherosclerosis, and migraine. In children, they are used for mental retardation, cerebrosthenic syndrome, oligophrenia, encephalopathy.
