Polymyxin E1 and polymyxin E2 are major active components in commercial colistin sulfate, and the others (polymyxin E3, E1-I, E1-7MOA) are less active.

Product of fine particle [100% pass through 20 mesh sieve (850μm)]2. Product of compacted particle[ ≥ 95% pass through 1400μm, and ≤40% pass through 355μm]?Biological properties?High effective against Gram-negative bacteria but little activity against Gram-positive bacteriaCompliance with PharmacopoeiaWe regularly supplies two different types of colistinsulfateto satisfy customers' needs. Those areproduct of fine powdered particle and compacted particle, respectively. The compacted type of colistin sulfate produced by dry granulation without addition of any excipient, has several advantages such as good flowability, excellent solubility, and less dust. ?Colistin sulfateconforms to EU Pharmacopoeia 9.0 (Furnished withCEP No. R0-CEP 2013-257-Rev 01)?Microbiological assay (dry basis): ≥19,000 IU/mg?Limit of polymyxin E3: ≤10.0%?Limit of polymyxin E1-I: ≤10.0%?Limit of polymyxin E1-7MOA: ≤10.0%?Sum of polymyxin E1, E2, E3, E1-Iand E1-7MOA: ≥ 77.0%?Colistin sulfateconforms to EU Pharmacopoeia 9.0(Continued) (Furnished withCEP No. R0-CEP 2013-257-Rev 01)?Polymyxin B2:≤2.0%?Impurity 1 (RRT0.18):≤1.5%?Impurity 2 (RRT0.23):≤2.0%?Impurity 3 (RRT0.34):≤1.5%?Impurity 4 (RRT0.37):≤1.5%?Impurity 5 (RRT0.42):≤2.0%?Impurity 6 (RRT0.93):≤2.0%?Impurity 7 (RRT0.27):≤1.0%?Any unspecified impurity:≤1.0%?Total of impurity:≤23.0%Indication and ApplicationColistin sulfate is mainly used for treatment of animals infected by Gram-negative bacteria like E. coli, pseudomonasand Acinetobacter spp.It is usually administered orally in feed, drinking water or milk replacer diet. Colistin sulfate is also used as a starting material to synthesize a human use drug of colistimethate sodium.Regulatory Compliances Following documents and certificates are available as requested;?Certificate of Suitability to the monographs of the European Pharmacopoeia(CEP)?EU Drug Master File (DMF) with full impurity profile complies with EMA requirements?EU GMP (Germany) Certificate?Australia GMP Compliance Letter?Chinese MOA GMP certificate?Letter of AccessAvailabilityBoth compacted non-sterile colistin sulfateand fine powdered non-sterile colistin sulfatecompliedwith EP 9.0(≥19,000 IU/mg) are available.
