Powder Sulfachloropyridazine Sodium is a synthetic antimicrobial agent belonging to the sulfonamide class, used primarily in veterinary medicine. It exhibits bacteriostatic properties, inhibiting the growth of a wide range of gram-positive and gram-negative bacteria by interfering with folic acid synthesis crucial for bacterial growth. As a sodium salt derivative of sulfachloropyridazine, it enhances solubility, making it suitable for oral administration in veterinary applications, particularly in poultry and livestock for treating respiratory and enteric infections. The compound is recognized for its efficacy against pathogens such as Escherichia coli, Salmonella spp., and Clostridium spp. However, its use necessitates careful monitoring to prevent resistance development and potential adverse effects. Regulatory bodies oversee its usage to ensure safety and efficacy, emphasizing proper dosage and withdrawal periods to maintain animal health and food safety standards.
