Lincomycin Hydrochloride

Lincomycin Hydrochloride is a lincosamide antibiotic produced through Streptomyces lincolnensis fermentation followed by controlled salt formation. It acts by binding to the bacterial 50S ribosomal subunit and inhibiting protein synthesis.

Supplied as a white crystalline powder, Lincomycin Hydrochloride is intended for veterinary pharmaceutical formulation development, including oral powders, premixes, and injectable formulations for livestock and companion animals.

Molecular Formula & Molecular Weight: C18H34N2O6S · HCl · H2O; molecular weight: 461.01 g/mol.

Antimicrobial Spectrum: Active primarily against susceptible Gram-positive bacteria and certain Mycoplasma species, including Staphylococcus aureus, Streptococcus species, and Mycoplasma hyopneumoniae.

Pharmacokinetic Profile: Absorption and tissue distribution depend on the selected dosage form, route of administration, and formulation.

Elimination: Primarily undergoes hepatic metabolism and is subsequently eliminated through biliary and renal pathways.

Particle Morphology: Controlled crystallization can be used to achieve a defined particle size distribution, supporting powder blending uniformity and formulation consistency.

Residual Solvent Management: Chromatographic and drying controls are applied to maintain residual solvents within applicable pharmaceutical specifications.

Thermal Processing Control: Controlled drying conditions help preserve chemical stability and minimize degradation during manufacturing and storage.

Powder Flowability: Controlled crystal morphology and particle-size distribution can improve powder handling, blending, and automated filling performance.

Swine Formulations: Used as an active pharmaceutical ingredient in veterinary formulations intended for susceptible bacterial and mycoplasmal infections in swine.

Poultry Formulations: May be incorporated into veterinary dosage forms for poultry applications where lincomycin is indicated by the applicable regulatory framework.

Companion Animal Formulations: Suitable for development of oral or parenteral veterinary dosage forms for dogs and cats where lincomycin therapy is appropriate.
