What is Colistin Sulphate?
Colistin Sulphate, a polypeptide-class antibiotic, is a critical agent in combating Gram-negative bacterial infections. With rising antimicrobial resistance, its role in veterinary medicine, aquaculture, and human healthcare (as a last-resort antibiotic) has gained prominence.
Pure colistin sulfate powder and colistin sulfate premix powder are the two most common powder forms of colistin sulfate.
Pure Colistin Sulphate Powder
Key Characteristics
Appearance: White or off-white crystalline powder.
Solubility: Highly soluble in water, slightly soluble in ethanol.
Stability: Stable under dry, cool conditions; degrades in strong acids/bases.
Mechanism Of Action Of Colistin Sulfate Powder
Colistin disrupts bacterial cell membranes by binding to lipopolysaccharides (LPS), causing leakage and cell death. It is effective against:
Gram-negative pathogens: E. coli, Klebsiella pneumoniae, Pseudomonas aeruginosa.
Resistant strains: Often used against carbapenem-resistant Enterobacteriaceae (CRE).
Applications
Veterinary Medicine: Treats enteric infections in livestock (pigs, poultry, cattle).
Aquaculture: Controls bacterial diseases in fish/shrimp.
Human Medicine: Reserved for multidrug-resistant infections (e.g., ICU-acquired pneumonia).
Quality Standards
High-purity (≥98%) Colistin Sulphate complies with USP, EP, and CP pharmacopeias, ensuring low endotoxin levels for injectable/oral use.
Storage: It requires proper storage conditions, typically in a cool, dry place to maintain its stability and efficacy.

Colistin Sulphate Premix Powder
Definition & Composition
A homogeneous blend of pure Colistin Sulphate with carriers (e.g., calcium carbonate, starch) for uniform feed incorporation.
Advantages
Dosing Accuracy: Ensures consistent drug delivery per ton of feed.
Ease of Use: Eliminates manual mixing errors.
Stability: Protects active ingredients during storage.
Common Specifications
Concentrations: 10%, 20%, or 50% premixes.
Dosage: 100–200g/ton feed (10% premix) for swine/poultry.
Use Cases
Swine: Prevents post-weaning diarrhea (E. coli).
Poultry: Manages necrotic enteritis.
Aquaculture: Treats Aeromonas infections.
