Calcitriol injection is indicated in the management of hypocalcemia in patients undergoing chronic renal dialysis. It has been shown to significantly reduce elevated parathyroid hormone levels. Reduction of PTH has been shown to result in an improvement in renal osteodystrophy. Calcitriol injection should not be given to patients with hypercalcemia or evidence of vitamin D toxicity. Calcitriol injection is contraindicated in patients with previous hypersensitivity to calcitriol or any of its excipients.

Calcitriol is a colorless, crystalline compound which occurs naturally
in humans. It is
soluble in organic solvents but relatively insoluble in water.
Calcitriol is chemically
designated (5Z, 7E)-9,10 secocholesta 5,7,10(19)-triene-1α, 3β,
25-triol and has the
following structural formula:
The other names frequently used for calcitriol are
1α,25-dihydroxycholecalciferol,1α, 25-
dihydroxyvitamin D ,1,25-DHCC,1,25(OH) D and 1,25-diOHC.
CLINICAL PHARMACOLOGY
Calcitriol is the active form of vitamin D (cholecalciferol). The
natural or endogenous
supply of vitamin D in man mainly depends on ultraviolet light for
conversion of 7-
dehydrocholesterol to vitamin D in the skin. Vitamin D must be
metabolically activated
in the liver and the kidney before it is fully active on its target
tissues. The initial
transformation is catalyzed by a vitamin D -25- hydroxylase enzyme
present in the liver,
and the product of this reaction is 25-(OH)D (calcifediol). The latter
undergoes
hydroxylation in the mitochondria of kidney tissue, and this reaction
is activated by the
renal 25-hydroxyvitamin D -1 α-hydroxylase to produce 1,25-(OH) D
(calcitriol), the
active form of vitamin D .
The known sites of action of calcitriol are intestine, bone, kidney
and parathyroid gland.
