Paricalcitol

Paricalcitol is a synthetic 1,25-dihydroxy vitamin D2 analog. As vitamin D deficiency, associated with chronic kidney disease, leads to an increase in parathyroid hormone (secondary hyperparathyroidism), paricalcitol is used in renal patients to block parathyroid hormone overproduction. Vitamin D deficiency is also a risk factor in cancer, cardiovascular disease, hypertension, and diabetes, and paricalcitol may have applications in those contexts as well.Formal Name: (1R,3R,5Z)-5-[(2E)-2-[(1R,3aS,7aR)-octahydro-1-[(1R,2E,4S)-5-hydroxy-1,4,5-trimethyl-2-hexen-1-yl]-7a-methyl-4H-inden-4-1,3-cyclohexanediol.
