DOXERCALCIFEROL

Renal Approved 2011-09-23

Doxercalciferol is a synthetic vitamin D2 analog that treats secondary hyperparathyroidism in adults. It helps patients with Stage 3 or 4 chronic kidney disease, as well as those who are currently on dialysis. This medication is used to help manage parathyroid hormone levels as kidney function declines.

How DOXERCALCIFEROL Works

This drug works by undergoing metabolic activation into an active metabolite that binds to vitamin D receptors. This binding triggers specific pathways that inhibit the synthesis and secretion of parathyroid hormone. By doing so, the medication effectively lowers PTH levels in the body.
