Cloxacillin

Cloxacillin is a penicillinase-stable isoxazolyl penicillin that resists beta-lactamase hydrolysis, used for infections caused by penicillinase-producing Staphylococcus aureus. Simson Pharma's Cloxacillin reference standard and impurities support compendial testing for this anti-staphylococcal beta-lactam.

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