Applications
1. Veterinary Antibacterial Agent
Sulfamethazine丨CAS 57-68-1 is commonly used to prevent and treat bacterial infections in livestock such as cattle, swine, sheep, and poultry. It is effective against a range of Gram-positive and Gram-negative bacteria, including:
E. coli
Streptococcus spp.
Salmonella spp.
Pasteurella spp.
It is indicated for conditions such as:
Respiratory tract infections
Enteritis and diarrhea
Coccidiosis
Mastitis and metritis
2. Growth Promotion and Disease Prevention
In some agricultural settings, sulfamethazine has historically been added to feed or water to enhance growth rates and reduce disease outbreaks, especially in intensive farming operations. Its preventive use helps reduce mortality and improve feed efficiency.
3. Combination Therapy
Sulfamethazine is frequently used in combination with other sulfonamides or trimethoprim, which enhances its spectrum of activity and efficacy. These combinations are used to:
Broaden antimicrobial coverage
Reduce resistance development
Provide synergistic effects in treating mixed infections
Benefits
1. Broad-Spectrum Antibacterial Activity
Sulfamethazine丨CAS 57-68-1 inhibits dihydropteroate synthase, a key enzyme in folic acid synthesis, which is critical for bacterial DNA and RNA production. This mechanism provides a broad-spectrum action against many bacterial and protozoal pathogens.
2. Cost-Effective and Widely Available
As a generic and established drug, sulfamethazine is affordable and readily accessible, making it ideal for large-scale veterinary applications.
3. Flexible Administration
It can be administered orally or parenterally, and is suitable for mass medication via feed or water, allowing efficient treatment of large herds or flocks.
4. Stable and Long Shelf Life
The compound is chemically stable under normal storage conditions, ensuring product reliability and longevity in field conditions.
