Paricalcitol Chemical Properties,Usage,Production

Description

Paricalcitol was launched as Zemplar in the US for the prevention and treatment of secondary hyperthyroidism associated with chronic renal failure. Paricalcitol is a synthetic vitamin D2, namely a novel 1-alpha-hydroxy-19-noranalogue in which the ring A exocyclic methylene group, typical of all vitamin D systems, has been replaced by two hydrogen atoms. Paricalcitol is the first vitamin D analogue marketed for this indication. In patients with chronic renal failure, Paricalcitol appreciably reduced levels of parathyroid hormone (PTH) without a significant difference in the incidence rate for hypercalcemia or hyperphosphatemia when compared with placebo.

Description

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.

Chemical Properties

White Solid

Uses

Antihyperparathyriod

Uses

1,25-Dihydroxy vitamin D2 is a potent agonist of the vitamin D receptor. 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.

Uses

Synthetic analog of vitamin D. Antihyperparathyroid.

Definition

ChEBI: Paricalcitol is a seco-cholestane and a hydroxy seco-steroid. It has a role as an antiparathyroid drug. It is functionally related to a vitamin D2.

brand name

Zemplar (Abbott).

Clinical Use

Vitamin D analogue:
Treatment and prevention of secondary hyperparathyroidism associated with chronic renal failure

Metabolism

Extensively metabolised via hepatic and non-hepatic pathways to form two relatively inactive metabolites. After oral administration of 3 H-paricalcitol, only about 2% of the dose was eliminated unchanged in the faeces, and no parent drug found in the urine.
Approximately 70% of the radioactivity was eliminated in the faeces and 18% was recovered in the urine. Most of the systemic exposure was from the parent drug.
