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 two to three 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
