Asenapine

Asenapine is an atypical antipsychotic with broad multi-receptor antagonism across dopamine, serotonin, adrenergic and histamine receptors, administered sublingually for schizophrenia and bipolar mania. Simson Pharma's Asenapine reference standard and impurities support stability-indicating method development for this sublingual antipsychotic.

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