Description

Cefquinome Sulphate is a fourth-generation cephalosporin antibiotic belonging to the veterinary pharmaceutical class. This compound is valued for its broad-spectrum activity against Gram-positive and Gram-negative bacteria, including β-lactamase producing strains. It is primarily required by manufacturers in the animal health industry for the formulation of injectable solutions to treat respiratory and other systemic infections in livestock, such as cattle and swine.

Application

• Veterinary Pharmaceutical Formulations: Primary active ingredient in injectable antibiotic solutions for livestock.
• Treatment of Bovine Respiratory Disease (BRD): Used to combat pneumonia and associated infections in cattle.
• Swine Health Management: Effective in treating systemic infections in pigs, including respiratory and septicemic conditions.
• Mastitis Treatment in Cattle: Applied in intramammary formulations for treating udder infections.
• Poultry Medicine: Potential use in treating bacterial infections in poultry, subject to regional regulatory approvals.
• Aquaculture: Investigated for use in controlling bacterial diseases in farmed fish.
• Research & Development: Serves as a reference standard in analytical laboratories and for developing new veterinary therapies.
• Generic Drug Manufacturing: Key ingredient for producers of generic veterinary cephalosporin products.
