Aztreonam

Aztreonam is a monobactam antibiotic featuring a monocyclic beta-lactam ring, offering targeted activity against aerobic Gram-negative organisms including Pseudomonas aeruginosa with minimal cross-reactivity in penicillin-allergic patients. Simson Pharma's Aztreonam reference standard and impurities support stability-indicating testing for this structurally distinct beta-lactam.

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