Anastrozole

Anastrozole is a non-steroidal aromatase inhibitor that blocks peripheral oestrogen synthesis, used as adjuvant endocrine therapy for hormone receptor-positive breast cancer in postmenopausal women. Simson Pharma's Anastrozole reference standard and impurities support the high-volume generic and stability-indicating testing this widely prescribed oncology agent requires.

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