Pharmaceutical compositions containing an iron complex of a 3-hydroxypyrid-2-one or 3-hydroxypyrid-4-one in which the hydrogen atom attached to the nitrogen atom is replaced by an aliphatic acyl group, by an aliphatic hydrocarbon group, or by an aliphatic hydrocarbon group substituted by one or, except in the case of ionizable groups, more than one substituent selected from aliphatic acyl, alkoxy, aliphatic amine, aliphatic amide, carboxy, aliphatic ester, halogen, hydroxy and sulpho groups and, optionally, in which one or more of the hydrogen atoms attached to ring carbon atoms are replaced by one of said substituents, by an aliphatic hydrocarbon group, or by an aliphatic hydrocarbon group substituted by an alkoxy, aliphatic ester, halogen or hydroxy group, but excluding compounds in which said replacement of hydrogen atoms in the compound is effected only by aliphatic hydrocarbon groups, are of value for the treatment of iron deficiency anemia.
含有3-羟基吡啶-2-酮或3-羟基吡啶-4-酮的铁配合物的制药组合物,其中连接到氮原子的氢原子被脂肪酰基、脂肪烃基或被脂肪烃基取代,或者被脂肪烃基取代,该脂肪烃基被选自脂肪酰基、烷氧基、脂肪胺基、脂肪酰胺基、羧基、脂肪酯基、卤素、羟基和磺酸基,并且可选地,其中连接到环碳原子的一个或多个氢原子被上述取代物之一取代,被烷氧基、脂肪酯基、卤素或羟基取代的脂肪烃基取代,但不包括只通过脂肪烃基进行氢原子取代的化合物,对于治疗缺铁性贫血具有价值。
