DESCRIPTION
Ergocalciferol Capsules, USP is a synthetic calcium regulator for oral
administration. Ergocalciferol
is a white, colorless crystal, insoluble in water, soluble in organic
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 capsule, 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,5_Z_,7_E_,22_E_)-; (C
H O) with a molecular weight of 396.65, and has the following
structural
formula:
INACTIVE INGREDIENTS: D&C Yellow No. 10, FD&C Blue No. 1, Gelatin,
Glycerin, Purified Water,
Refined Soybean Oil.
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-dihydroxy- vitamin D). Vitamin D metabolites
promote the active absorption of
calcium and phosphorus 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 sy
