Chronic Kidney Disease Stages 3 And 4: Paricalcitol capsules are indicated in adults and pediatric patients 10 years of age and older for the prevention and treatment of secondary hyperparathyroidism associated with Chronic Kidney Disease (CKD) Stages 3 and 4.

Chronic Kidney Disease Stage 5: Paricalcitol capsules are indicated in adults and pediatric patients 10 years of age and older for the prevention and treatment of secondary hyperparathyroidism associated with CKD Stage 5 in patients on hemodialysis (HD) or peritoneal dialysis (PD).

Paricalcitol is a synthetic, biologically active vitamin D analog of calcitriol with modifications to the side chain (D2) and the A (19-nor) ring. Preclinical andin vitro studies have demonstrated that paricalcitol's biological actions are mediated through binding of the VDR, which results in the selective activation of vitamin D responsive pathways. Vitamin D and paricalcitol have been shown to reduce parathyroid hormone levels by inhibiting PTH synthesis and secretion.

Usual Adult Dose for Secondary Hyperparathyroidism:

Initial dose:

Stage 3 or 4 Chronic Kidney Disease (CKD): Initial dosing is based on baseline intact parathyroid hormone (iPTH):

• 500 pg/mL or less: 1 mcg orally daily OR 2 mcg orally 3 times a week
• Over 500 pg/mL: 2 mcg orally daily OR 4 mcg orally 3 times a week

Stage 5 Chronic Kidney Disease (CKD):

• Starting dose (micrograms) = baseline iPTH level (pg/mL)/80
• Starting dose is given orally 3 times a week; only start if baseline serum calcium has been adjusted to 9.5 mg/dL or lower.

Usual Pediatric Dose for Secondary Hyperparathyroidism:

Safety and efficacy have not been established in pediatric patients. The following is dosing used in a very small pediatric trial. No data are available on children under 5 years old.

Initial dose, children 5 to 18 years: 0.04 mcg/kg three times per week if baseline intact parathyroid hormone (iPTH) is less than 500 pg/mL 0.08 mcg/kg three times per week if baseline iPTH is 500 pg/mL or higher. Injected as a bolus dose through a hemodialysis vascular access port at any time during dialysis

Maximum frequency: Every other day
