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 .
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.
The active vitamin D metabolite, calcitriol, exerts its biological effects by binding to the vitamin D receptor (VDR), which is primarily located in the nuclei of target cells. [ 1 ] [ 13 ] When calcitriol binds to the VDR, it enables the receptor to act as a transcription factor , modulating the gene expression of transport proteins involved ...
Top Prescription Weight Loss Pills. Anti-obesity medications (AOMs) date back to the 1940s — well before modern regulations from the FDA (U.S. Food and Drug Administration) (FDA) were in place ...

Calcitriol was identified as the active form of vitamin D in 1971 and the drug was approved for medical use in the United States in 1978. [7] It is available as a generic medication . [ 12 ] In 2022, it was the 254th most commonly prescribed medication in the United States, with more than 1 million prescriptions.
A 2024 review in The Lancet Diabetes & Endocrinology found that muscle loss is a major side effect from taking weight-loss medications like GLP-1s, which makes getting adequate protein in during ...
However, it has been shown to have comparable affinity with calcitriol for the vitamin D receptor (VDR), while being less than 1% as active as the calcitriol in regulating calcium metabolism. The vitamin D receptor belongs to the steroid/thyroid receptor superfamily, and is found on the cells of many different tissues including the thyroid ...
