NEW LOW MOLECULAR WEIGHT COMPLEXES BETWEEN IRON AND MALTOBIONIC ACID, USE THEREOF FOR INTRAMUSCULAR OR SUBCUTANEOUS ADMINISTRATION IN THE TREATMENT OF ANEMIC STATES, AND NEW PHARMACEUTICAL COMPOSITIONS ADAPTED FOR THESE USES

摘要

New low molecular weight complexes between iron and maltobionic acid that can be administered parenterally, preferably intramuscularly or subcutaneously, in the treatment of anemic states, caused by iron deficiencies, and new pharmaceutical compositions adapted for this use. In particular, the invention provides a new complex between preferably trivalent iron and maltobionic acid that is characterized by a molecular weight Mw between 10,000 and 30,000 Da, by a polydispersity of 1.0-1.8 and by an iron content between 25% and 40% by weight.
