Sulphadimidine

Sulphadimidine

Sulphadimidine (also known as Sulfamethazine) is a widely established sulfonamide antibiotic renowned for its high efficacy and broad-spectrum activity in veterinary medicine. It acts against a vast array of Gram-positive and Gram-negative bacteria, including Pasteurella, Salmonella, Escherichia coli, and Streptococcus, as well as protozoal parasites causing coccidiosis. Sulphadimidine works by inhibiting the bacterial synthesis of folic acid, effectively arresting the growth of pathogens. It is a first-line choice for treating respiratory diseases (such as shipping fever and pneumonia), gastrointestinal infections (scours), foot rot, and calf diphtheria. Available in various forms—including oral boluses, tablets, feed premixes, and injectable solutions—it offers versatile and cost-effective treatment options for individual animal therapy or herd health management.
