Summary for Patent: 8,926,947
Title:Polyol and polyether iron oxide complexes as pharmacological and/or MRI contrast agents
Abstract: Iron oxide complexes, pharmacological compositions and unit dosage thereof, and methods for their administration, of the type employing an iron oxide complex with a polyol, are disclosed. The pharmacological compositions employ a polysaccharide iron oxide complex, wherein the polysaccharide is a modified polyol such as a carboxyalkylated reduced dextran. The complex is stable to terminal sterilization by autoclaving. The compositions are suitable for parenteral administration to a subject for the treatment of iron deficiencies or as MRI contrast agent.
