Cyproterone

Cyproterone is a steroidal antiandrogen and progestogen that competitively blocks androgen receptors, used in the treatment of prostate cancer, androgen-dependent alopecia, acne and hirsutism, typically as its acetate ester. Simson Pharma's Cyproterone reference standard and impurities support compendial testing across these anti-androgen applications.

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