Abstract
Water soluble Iron carbohydrate complex obtainable from an aqueous solution of iron(III) salt and an aqueous solution of the oxidation product of one or more maltrodextrins using an aqueous hypochlorite solution at a pH-value within the alkaline range, where, when one maltodextrin is applied, its dextrose equivalent lies between 5 and 20, and when a mixture of several maltodextrins is applied, the dextrose equivalent of the mixture lies between 5 and 20 and the dextrose equivalent of each individual maltodextrin contained in the mixture lies between 2 and 40, process for its production and medicament for the treatment and prophylaxis of iron deficiency conditions.
Claims26
An iron (III) carboxymaltodextrin complex wherein said iron (III) carboxymaltodextrin complex comprises polynuclear iron (III)-hydroxide 4(R)-(poly-(1→4)-O-α-D-glucopyranosyl)-oxy-2(R),3(S),5(R),6-tetrahydroxy-hexanoate and has a weight average molecular weight in the range of from 80 kDa to 400 kDa, and wherein said 4(R)-(poly-(1→4)-O-α-D-glucopyranosyl)-oxy-2(R),3(S),5(R),6-tetrahydroxy-hexanoate is derived from the oxidation of maltodextrin, wherein when one maltodextrin is applied its dextrose equivalent lies between 5 and 20, and when a mixture of several maltodextrins is applied, the dextrose equivalent of the mixture lies between 5 and 20 and the dextrose equivalent of each individual maltodextrins contained in the mixture lies between 2 and 40.
