Calcitriol, Rocaltrol is the active form of vitamin D (1,25 hydroxyvitamin D3).  It binds to and activates the vitamin D receptor in the kidney, parathyroid gland, intestine, and bone, stimulating intestinal calcium transport and absorption. It reduces parathyroid hormone (PTH) levels and improves calcium and phosphate homeostasis by stimulating bone resorption of calcium and increasing renal tubular reabsorption of calcium.

Hypoparathyroidism/pseudohypoparathyroidism and secondary hyperparathyroidism in patients with chronic kidney disease.

Before starting Calcitriol, Rocaltrol make sure your physician is aware of any allergies or medications you currently take, if you have kidney disease, or malabsorption syndrome.  Calcium levels must be monitored closely as excessive vitamin D may lead to over suppression of parathyroid hormone, hypercalcemia, hypercalciuria, hyperphosphatemia and adynamic bone disease. Chronic hypercalcemia can result in generalized vascular and soft tissue calcification, exacerbate nephrolithiasis, and has been associated with increased mortality in adults with chronic kidney disease.

Oral: Initial: 0.25 mcg once daily (may adjust dose at 2- to 4-week intervals to achieve target calcium levels while avoiding hypercalcemia); range: 0.5 to 2 mcg/day.

Secondary hyperparathyroidism in patients with chronic kidney disease has more complex dosing.

How Do You Take Calcitriol, Rocaltrol:  Oral form may be administered without regard to food, but administer with meals to reduce GI problems. Intravenous therapy may be administered as a bolus dose through the catheter at the end of hemodialysis. Adequate calcium intake should be maintained during therapy; dietary phosphorous may need to be restricted.

Hypercalcemia, headache, skin rash, polydipsia, nausea.
