Calcium Folinate

Calcium Folinate (leucovorin calcium) is the calcium salt of folinic acid, used to rescue normal cells from methotrexate toxicity and to enhance the cytotoxic activity of 5-fluorouracil in colorectal cancer protocols. Simson Pharma's Calcium Folinate reference standard and impurities support potency and stability testing of this essential oncology-support injectable.

Simson Pharma Global Ltd. (UK) and Simson Pharma Global LLC (USA) supply high-quality Calcium Folinate Reference Standards, pharmacopoeial reference materials, and its related impurities to pharmaceutical manufacturers, CROs, analytical laboratories, universities, and regulatory organizations worldwide. To service the Europe and America market efficiently, Simson Pharma Limited has set up Simson Pharma Global Ltd. in United Kingdom and Simson Pharma Global LLC in USA respectively.
