Colistin sulfate is a sulfate salt of the mixture of polymixins which areclosely related antimicrobial polypeptides produced by Bacillus polymyxa var. colistinus. Polymyxin E₁ and polymyxin E₂ are major active components in commercial colistin sulfate, and the others (polymyxin E₃, E_1-I, E_1-7MOA) are less active.  

Characteristics
ØNomenclature
•International Nonproprietary Name (INN):Colistin sulfate
•Compendial name: Colistin sulfate

•Relative molecular mass: 1155-1170
•Company's code: LNE
•Chemical Abstracts Service (CAS) registry number: 1264-72-8

ØPhysico-chemical properties
•White or almost white, hygroscopic powder
•Freely soluble in water, practically insoluble in acetone and in ethanol.
•Non-sterilegrade
•Type of particle:
1. 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]

ØBiological properties

Compliance with Pharmacopoeia
We 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.

Indication and Application
Colistin 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.
