Calcitriol

Calcitriol (1,25-dihydroxyvitamin D3) is the fully active hormonal form of vitamin D that promotes intestinal calcium absorption and regulates bone mineralisation, used for renal osteodystrophy, hypoparathyroidism and osteoporosis. Simson Pharma's Calcitriol reference standard and impurities support the exacting stability-indicating testing this potent, light-sensitive vitamin D hormone requires.

Simson Pharma Global Ltd. (UK) and Simson Pharma Global LLC (USA) supply high-quality Calcitriol 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.
