  • Patent number: 12239657
    Abstract: Injectable iron compositions comprising iron, a carbohydrate, a stabilizing agent and water are provided. These iron compositions can be prepared by mixing iron with a carbohydrate and water to form a mixture and adding a stabilizing agent to the mixture to form the stable injectable iron composition. These compositions can be considered “ready-to-use” and can treat a variety of diseases, disorders, or conditions characterized by iron deficiency or dysfunctional iron metabolism, for example, anemia.
