USPTO Abstract

An iron-dextrin compound for treatment of iron deficiency anaemia comprising hydrogenated dextrin having a weight average molecular weight equal to or less than 3,000 Dalton and a number average molecular weight equal to or higher than 400 Daltons, in stable association with ferric oxyhydroxide. As the molecular weight of the dextrin must be narrow it is another important feature of the invention that the 10 % fraction of the dextrins having the highest molecular weight has an average molecular weight of less than 4500 Daltons, and that 90 % of the dextrins are having molecular weights of less than 3000 Daltons. It is further important that the 10 % fraction having the lowest molecular weight has a weight average molecular weight of 340 Daltons or more.
