Paricalcitol (chemically it is 19-nor-1,25-(OH) 2-vitamin D 2. Marketed by Abbott Laboratories under the trade name Zemplar ) is a drug used for the prevention and treatment of secondary hyperparathyroidism (excessive secretion of parathyroid hormone ) associated with chronic kidney failure .
Calcitriol also reduces calcium loss to urine. [215] Per the diagram, calcitriol suppresses the parathyroid hormone gene, thus creating a negative feedback loop that combines to tightly maintain plasma calcium in a normal range of 2.1-2.6 mmol/L for total calcium and 1.1-1.3 mmol/L for ionized calcium.

8 Weight Loss Vitamins and Supplements to Boost Metabolism. Most of the supplements that can be used as part of an effective weight loss routine are naturally occurring, meaning you can get them ...
The natural, active form of vitamin D is calcitriol (1,25-dihydroxycholecalciferol). This molecule and other naturally occurring forms of vitamin D, including its precursors and metabolites, have been modified to synthesize pharmaceuticals with potentially greater, or selective, therapeutic actions.

Calcitriol is a hormone and the active form of vitamin D, normally made in the kidney. [ 8 ] [ 9 ] [ 10 ] It is also known as 1,25-dihydroxycholecalciferol . It binds to and activates the vitamin D receptor in the nucleus of the cell, which then increases the expression of many genes. [ 11 ]
The new guidelines still prioritize lifestyle changes, but they also say weight-loss medications should be offered in addition to children over 12, when the balance of risks and benefits makes sense.
The vitamin D receptor (VDR also known as the calcitriol receptor) is a member of the nuclear receptor family of transcription factors. [5] Calcitriol (the active form of vitamin D , 1,25-(OH) 2 vitamin D 3 ) binds to VDR, which then forms a heterodimer with the retinoid-X receptor .
