Shelcal-OS Tablet is a combination of Alfacalcidol & Calcium carbonate.
Alfacalcidol is converted to active calcitriol by 25-hydroxylation in the liver. Calcitriol increases the serum calcium concentrations by increasing GI absorption of phosphorus and calcium, increasing osteoclastic resorption and increasing distal renal tubular reabsorption of calcium. Calcitriol appears to promote intestinal absorption of calcium through binding to the vitamin D receptor in the mucosal cytoplasm of the intestine. Subsequently, calcium is absorbed through formation of a calcium-binding protein.
