Colistin Sulphate BP

Colistin Sulphate BP is an antibiotic belonging to the polymyxin class, derived from the bacterium Paenibacillus polymyxa. It is a white to pale yellow powder, soluble in water, and used primarily for its potent bactericidal activity against Gram-negative bacteria, including multidrug-resistant strains. Colistin Sulphate BP is used in both human and veterinary medicine, often as a last-resort treatment for serious infections caused by multidrug-resistant Pseudomonas, Acinetobacter, and Klebsiella species. Due to its efficacy and narrow therapeutic index, its use is carefully monitored. The “BP” denotes compliance with the British Pharmacopoeia standards.
