Enerion® (Sulbutiamine) 2


Enerion is a synthetic substance; its structure is close to thiamine, compared to which the molecule has an open thiazole cycle, an additional disulfide bond, and a lipophilic ether. Due to this modification, Sulbutiamine is well soluble in fat; it is quickly absorbed from the digestive tract and easily penetrates into the blood-brain barrier (BBB). In contrast to thiamine, it can accumulate in the cells of the reticular formation, in the hippocampus and the dentate gyrus, as well as in the Purkinje cells and in the glomeruli of the granular layer of the cerebellar cortex. Enerion improves the coordination of movement and resistance to physical exercise, the stability of the cerebral cortex structures becomes more resistant to repeated anoxia. The medicine is effective for the symptomatic treatment of functional asthenia.


Sulbutiamine is quickly absorbed from the gastrointestinal tract. The maximum concentration in blood plasma is reached 1-2 hours after an intake. The half-life is about 5 hours. The medicine is excreted in the urine.
