Mechanism of action Vitamin B1 - Thiamine

VITAMIN B1 ® is a thiamine-based drug, a key vitamin in balancing the energy and biosynthetic state of the human body. Concentrated in tissues such as the heart and the nervous system, mainly in the form of thiamine pyrophosphate, it acts as a cofactor of decarboxylase and transketolase, involved respectively in the generation of energy from various macromolecules and in the synthesis of nucleic acids. The deficiency of this vitamin, fortunately rare and present especially in some risk categories such as alcoholics, manifests itself with an intense neuropathy characterized by intense pain in the extremities, seizures and in the most severe cases with encephalopathy. Under these conditions, the intake of parenteral thiamine can cause a rapid regression of symptoms, significantly improving the patient's health conditions. Studies performed and clinical efficacy 2.
