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.
