Cyproheptadine

Cyproheptadine is a first-generation H1-receptor antagonist with additional serotonin antagonism and anticholinergic activity, used for allergic conditions and as an appetite stimulant, particularly in paediatric and wasting-disease contexts. Simson Pharma's Cyproheptadine reference standard and impurities support compendial testing for this multi-receptor antihistamine.

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