Baclofen

Baclofen is a GABA-B receptor agonist that acts centrally to reduce excessive muscle tone, making it a mainstay therapy for spasticity associated with multiple sclerosis and spinal cord injury. Simson Pharma's Baclofen reference standard and impurities support compendial testing across oral and intrathecal formulations.

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