This formulation is a synergistic combination of Sulphachlorpyridazine, a potent sulphonamide antibiotic, and Trimethoprim, a diaminopyrimidine antibacterial. Together, they act by sequentially inhibiting bacterial folic acid synthesis — enhancing bacteriostatic and bactericidal activity against a broad range of Gram-positive and Gram-negative organisms. Ideal for oral treatment via feed or water in livestock and poultry.
