Salinomycin sodium salt is primarily used as an antibiotic in veterinary medicine, particularly for controlling coccidiosis in poultry and livestock. It is effective against a broad spectrum of gram-positive bacteria and certain parasites, making it a valuable tool in animal health management. Additionally, it has gained attention in cancer research due to its ability to selectively target cancer stem cells, showing potential in inhibiting tumor growth and metastasis. Its use in this field is still under investigation, but it holds promise as a novel therapeutic agent. In agriculture, it is sometimes employed as a feed additive to improve growth efficiency and overall health in animals. However, its application requires careful regulation to avoid resistance development and ensure safety.
