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.
