Biochem/physiol Actions

Agonist for the calcitriol (Vitamin D receptor); Vitamin D analog; Antihyperparathyroid.

Paricalcitol is Vitamin D analog that acts as an agonist for the calcitriol receptor (Vitamin D receptor, VDR). It suppresses parathyroid hormone (PTH) gene transcription and PTH secretion and has been used clinically because of its antihyperparathyroid activity without inducing hypercalcemia or hyperphosphatemia. There is growing evidence that vitamin D either directly or indirectly affects cardiac structure and function. Paricalcitol showed improvement of cardiac function after myocardial infarction in mice with decreases in biomarkers, apoptosis, inflammation, and fibrosis.
