Carbocysteine

Carbocysteine is a mucolytic agent that restores normal mucus viscosity by modifying disulfide bonds and stimulating serous gland secretion, widely used for chronic obstructive and inflammatory respiratory conditions. Simson Pharma's Carbocysteine reference standard and impurities support compendial testing for this globally popular mucolytic.

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