Therapeutic indications:

Thiamine hydrochloride injection is effective for the treatment of thiamine deficiency or beriberi whether of the dry (major symptoms related to the nervous system) or wet (major symptoms related to the cardiovascular system) variety. Thiamine hydrochloride injection should be used where rapid restoration of thiamine is necessary, as in Wernicke's encephalopathy, infantile beriberi with acute collapse, cardiovascular disease due to thiamine deficiency, or neuritis of pregnancy if vomiting is severe. It is also indicated when giving IV dextrose to individuals with marginal thiamine status to avoid precipitation of heart failure. Thiamine hydrochloride injection is also indicated in patients with established thiamine deficiency who cannot take thiamine orally due to coexisting severe anorexia, nausea, vomiting, or malabsorption. Thiamine hydrochloride injection is not usually indicated for conditions of decreased oral intake or decreased gastrointestinal absorption, because multiple vitamins should usually be g

CLINICAL PHARMACOLOGY
The water soluble vitamins are widely distributed in both plants and
animals. They are absorbed in man
by both diffusion and active transport mechanisms. These vitamins are
structurally diverse (derivatives
of sugar, pyridine, purines, pyrimidine, organic acid complexes and
nucleotide complex) and act as
coenzymes, as oxidation-reduction agents, possibly as mitochondrial
agents. Metabolism is rapid, and
the excess is excreted in the urine.
Thiamine is distributed in all tissues. The highest concentrations
occur in liver, brain, kidney and heart.
When thiamine intake is greatly in excess of need, tissue stores
increase 2 to 3 times. If intake is
insufficient, tissues become depleted of their vitamin content.
Absorption of thiamine following IM
administration is rapid and complete.
Thiamine combines with adenosine triphosphate (ATP) to form thiamine
pyrophosphate, also known as
cocarboxylase, a coenzyme. Its role in carbohydrate metabolism is
