Overview


Florfenicol Solution 10% is a veterinary formulation designed for the prevention and treatment of bacterial infections in livestock. It contains 10% w/v of Florfenicol, a synthetic broad-spectrum antibiotic derived from thiamphenicol, offering potent activity against both Gram-positive and Gram-negative bacteria.

Unlike the raw API, which serves as the active pharmaceutical ingredient for manufacturing, this 10% solution is a ready-to-use veterinary preparation suitable for oral or parenteral administration. It is characterized by its high bioavailability, consistent efficacy, and excellent safety margin in cattle, pigs, and poultry.
