CYANOCOBALAMIN INJECTION USP 1000 MCG/ML
DESCRIPTION
Cyanocobalamin Injection, USP is a sterile solution of cyanocobalamin
for intramuscular
or subcutaneous use.
Each mL contains 1,000 mcg cyanocobalamin; sodium chloride 0.9%;
benzyl alcohol
1.5%; Water for Injection q.s.; Hydrochloric acid and/or sodium
hydroxide for pH
adjustment if necessary (4.5-7.0).
Cyanocobalamin appears as dark, red crystals or as an amorphous or
crystalline, red
powder. It is very hygroscopic in the anhydrous form, and sparingly
soluble in water
(1:80). It is stable to autoclaving for short periods at 121°C. The
Vitamin B
coenzymes are very unstable in light.
The chemical name is 5,6-dimethyl-benzimidazolyl cyanocobamide. The
cobalt content is
4.34%. The structural formula is represented below:
CLINICAL PHARMACOLOGY
Vitamin B
is essential to growth, cell reproduction, hematopoiesis,
nucleoprotein and
myelin synthesis.
Cyanocobalamin is quantitatively and rapidly absorbed from
intramuscular and
subcutaneous sites of injection; the plasma level of the compound
reaches its peak
within one hour after intramuscular injection. Absorbed Vitamin B
is transported via
specific B
binding proteins, transcobalamin I and II to the various tissues. The
liver is
the main organ for Vitamin B
storage.
Within 48 hours after injection of 100 or 1,000 mcg of Vitamin B
, 50 to 98% of the
injected dose may appear in the urine. The major portion is excreted
within the first eight
hours. Intravenous administration results in even more rapid excretion
with little
opportunity for liver storage.
Gastrointestinal absorption of Vitamin B
depends on the presence of sufficient

intrinsic factor and calcium ions. Intrinsic factor deficiency causes
pernicious anemia,
which may be associated with subacute combined degeneration of the
spinal cord.
Prompt parenteral administration of Vitamin B
prevents progression of neurologic
damage.
The average diet supplies about 5 to 15 mcg/day
