Description

Marbofloxacin (Hydrochloride) is a synthetic, broad-spectrum fluoroquinolone antibiotic belonging to the third generation of this important pharmaceutical class. It is valued for its potent activity against a wide range of Gram-positive and Gram-negative bacteria, including mycoplasmas. This compound is primarily utilized as a key active pharmaceutical ingredient (API) in the formulation of veterinary medicinal products for companion animals and livestock. Its efficacy and pharmacokinetic profile make it a critical component in addressing bacterial infections in the global animal health sector.

Application

• Veterinary Pharmaceutical API: Primary use as the active ingredient in injectable and oral formulations for treating bacterial infections in animals.
• Companion Animal Medicine: Treatment of skin, soft tissue, and urinary tract infections in dogs and cats.
• Livestock Health Management: Control of respiratory diseases (e.g., bovine respiratory disease) and other systemic infections in cattle and swine.
• Poultry Health: Management of bacterial conditions in poultry flocks.
• Research & Development: Used as a reference standard in analytical laboratories and for pharmacological studies.
• Veterinary Generic Drug Manufacturing: Sourcing for the production of generic veterinary fluoroquinolone products.
