Pyritinol also called pyridoxine disulfide or pyrithioxine (European drug names Encephabol Encefabol Cerbon 6) is a semi-natural water soluble analog of vitamin B6 (Pyridoxine HCl). It was produced in 1961 by Merck Laboratories by bonding 2 vitamin B6 compounds (pyridoxine) together with a disulfide bridge. Since the 1970s it has been a prescription and OTC drug in several countries for cognitive disorders and learning disorders in children.
