Thiamine, also known as vitamin B1, plays a key role in the human metabolism. It is present in many dietary sources such as meats, eggs, fish, beans and peas, nuts, and whole grains. Upon administration thiamine is converted by thiamine pyrophosphokinase-1 (TPK1) to the active form, thiamine pyrophosphate, which serves as a cofactor for enzymes involved in the TCA cycle and the non-oxidative part of the pentose phosphate pathway. The lack of thiamine may cause the thiamine deficiency. The classical syndrome caused primarily by thiamine deficiency in humans is beriberi, however, symptoms of thiamine deficiency also include congestive heart failure, metabolic acidosis, confusion, ataxia and seizures. Thiamine is a component of many vitamin complexes, which are approved for the treatmen and prevention of general vitamin deficiency, including the thiamine deficiency.

Sample Use Guides

In Vivo Use Guide

The starting dose (as a component of M.V.I.–12) is one 10 mL daily dose added directly to an intravenous fluid.

Route of Administration: Intravenous

In Vitro Use Guide

Human Caco-2 cells were incubated (37 Celsius) in Krebs-Ringer buffer (pH 7.4) for different periods of time in the presence of 0.1 uM and 10 uM thiamine. The uptake study demonstrated that thiamine is transported across the cell membrane with Michaelis-Menten constant of 3.18 uM.
