Iron complex compounds for therapeutic use

The present invention relates to pharmaceutical composition comprising an iron carbohydrate complex for use in a method for treatment or prevention of Restless Leg Syndrome (RLS) of a human patient, wherein the human patient prior to treatment has a magnetic resonance phase imaging of 0.02 radians above the average value of a control group in the substantia nigra, thalamus, putamen, orpallidum. The invention provides a higher probability for a RLS patient being treated to experience a relief in symptoms.

The present invention relates to an iron carbohydrate complex for use in a method of increasing the blood haemoglobin concentration in a pregnant non-human mammal, wherein the pregnant non-human mammal having a blood haemoglobin level of 105 g/L or less, is administered one or more doses of iron carbohydrate complex comprising an amount of elemental iron of 1800 mg or more per dose. The method relates to the further effects of decreasing the rate of stillborn offsprings from a pregnant non-human mammal having a blood haemoglobin level of 105 g/L or less, increasing the blood haemoglobin concentration of offspring litters within 3 days from birth and/or weaning, or increasing the litter size in a subsequent parity of a non-human mammal having a blood haemoglobin level of 105 g/L or less.

Iron carbohydrate complex for treatment of fetal metal deficiency Disclosed herein is a pharmaceutical composition comprising an iron carbohydrate complex for use in a method for treatment or prevention of an iron deficiency of a fetus or an infant, wherein the iron carbohydrate complex is administered to the mother of the fetus or infant.

The invention relates to an iron oligosaccharide compound with improved stability comprising a hydrogenated oligosaccharide in stable association with ferric oxyhydroxide, the content of dimes saccharide in said hydrogenated oligosaccharide being 2.9% by weight or less, based on the total weight of the hydrogenated oligosaccharide. In further aspects is provided a process for preparing said compound as well as the use of said compound for preparation of a composition for treatment of iron deficiency anaemia.

In a process for producing an iron-dextran compound for use in parenteral treatment of iron-deficiency in humans or animals a stable compound of desired relatively low molecular weight is obtained by using first hydrogenation and then oxidation to convert reducing terminal groups on the dextran molecules before reaction with the iron. By varying the ratio of hydrogenated groups to oxygenated groups the average molecular weight of the resulting iron-dextran compound can be varied.

Process for producing an iron-dextran compound, iron-dextran compound produced according to said process, pharmaceutical composition for prophylaxis or treatment of iron-deficiency and use of said compound for the preparation of parenterally administrable pharmaceutical composition

An iron-dextran compound for parenteral treatment of iron-deficiency anemia comprises hydrogenated dextran having a weight average molecular weight (Mw) between 700 and 1,400 Daltons, preferably approximately 1,000 Daltons, a number average molecular weight (Mn) of 400 to 1,400 Daltons and wherein 90% by weight of the dextran has molecular weights less than 2,700 Daltons and the Mw of the 10% by weight fraction of the dextran having the highest molecular weights is below 3,200 Daltons, said hydrogenated dextran having been subjected to purification by membrane processes having a cut-off value between 340 and 800 Daltons, in stable association with ferric oxyhydroxide. The compound is produced by using membrane processes to eliminate dextrans of higher molecular weights than approximately 2,700 Daltons and membrane processes to remove saccharides of molecular weights below approximately 340 Daltons from hydrogenated dextran before precipitating ferric hydroxide in the presence of said dextran followed by heat treatment and purification.
