Uniplar 1 mcg Capsule contains Paricalcitol, a synthetic vitamin D analog indicated for the prevention and treatment of secondary hyperparathyroidism (SHPT) in patients with chronic kidney disease (CKD), stages 3–5. It acts by selectively binding to and activating the vitamin D receptor in parathyroid tissue, thereby reducing parathyroid hormone (PTH) synthesis and secretion without significantly increasing calcium and phosphorus levels.
