DESCRIPTION
ERGOCALCIFEROL CAPSULES, USP, is a synthetic calcium regulator for
oral
administration. Ergocalciferol is a white, colorless crystal,
insoluble in water, soluble
inorganic solvents, and slightly soluble in vegetable oils. It is
affected by air and by light.
Ergosterol or provitamin D
is found in plants and yeast and has no antirachitic activity.
There are more than 10 substances belonging to a group of steroid
compounds,
classified as having vitamin D or antirachitic activity.
One USP Unit of vitamin D
is equivalent to one International Unit (IU), and 1 mcg of
vitamin D
is equal to 40 IU.
Each softgel, for oral administration, contains Ergocalciferol, USP
1.25 mg (equivalent to
50,000 USP units of Vitamin D), in an edible vegetable oil.
Ergocalciferol, also called vitamin D
, is 9,10-secoergosta-5,7,10(19),22-tetraen-3-
ol,(3β,5Z,7E,22E)-; (C
H
O) with a molecular weight of 396.65, and has the following
structural formula:
INACTIVE INGREDIENTS : Refined soybean oil, gelatin, glycerin,
purified water, D&C Yellow
#10, and FD&C Blue #1.
CLINICAL PHARMACOLOGY
The _in vivo _synthesis of the major biologically active metabolites
of vitamin D occurs in
two steps. The first hydroxylation of ergocalciferol takes place in
the liver (to 25-

hydroxyvitamin D) and the second in the kidneys (to
1,25-dihydroxyvitamin D). Vitamin
D metabolites promote the active absorption of calcium and phosphorous
by the small
intestine, thus elevating serum calcium and phosphate levels
sufficiently to permit bone
mineralization. Vitamin D metabolites also mobilize calcium and
phosphate from bone
and probably increase the reabsorption of calcium and perhaps also of
phosphate by
the renal tubules.
There is a time lag of 10 to 24 hours between the administration of
vitamin D and the
initiation of its action in the body due to the necessity of synthesis
of the active
metabolites in the liver and kidneys.
