Sulfasuccinamide is primarily used in the field of veterinary medicine as an effective antibacterial agent. It is commonly administered to livestock, such as cattle and poultry, to treat and prevent bacterial infections, particularly those affecting the gastrointestinal and respiratory systems. Its broad-spectrum activity makes it suitable for combating a variety of pathogens, ensuring the health and productivity of animals. Additionally, it is sometimes incorporated into animal feed or water to provide continuous protection against bacterial diseases. In some cases, it is also used in combination with other therapeutic agents to enhance its efficacy and reduce the risk of resistance development.
