Fursultiamine

Fursultiamine (INN; Adventan, Alinamin-F, Benlipoid, Bevitol Lipophil, Judolor), also known as thiamine tetrahydrofurfuryl disulfide (TTFD), is a disulfide derivative of thiamine, or an allithiamine. It was synthesized in Japan in the 1960s for the purpose of developing forms of thiamine with improved lipophilicity for treating vitamin B₁ deficiency (i.e., beriberi), and was subsequently commercialized not only in Japan but also in Spain, Austria, Germany, and the United States. As a vitamin, it is available over-the-counter as well.
