Therapeutic Interchange:
Ochsner Health System (OHS) carries multiple products, strengths and formulations of calcium supplements on system formulary, including calcium
carbonate (tablet, chewable tablet, suspension), calcium carbonate-vitamin D3, calcium citrate, calcium citrate-vitamin D3, and calcium glubionate.
The calcium supplements were reviewed to evaluate opportunities for formulary standardization and cost savings through therapeutic interchanges
Among calcium supplements on formulary, calcium carbonate chewable tablet has highest utilization, more elemental calcium per tablet, is well absorbed with food and less expensive. Calcium citrate has some advantages, having less dependence on stomach acid for absorption and less constipation. However, it has less elemental calcium which requires more tablets per dose and is more expensive. Generally, calcium supplements can decrease the absorption of other medications, such as bisphosphonates, tetracyclines, levothyroxine, quinolones, iron preparations, iron containing multivitamins, mycophenolate, and riociguat. Doses of calcium supplements should be separate from these medications.
