Compounds which are a 1-hydroxypyrid-2-one in which one or more of the hydrogen atoms attached to ring carbon atoms are eplaced by a substituent selected from aliphatic acyl, aliphatic amide, aliphatic amine, carboxy, cyano, aliphatic ester, halogen, hydroxy and sulpho groups, alkoxy groups and alkoxy groups substituted by an alkoxy, aliphatic amide, aliphatic amine, alipha- :ic ester, halogen or hydroxy group, aliphatic hydrocarbon groups and aliphatic hydrocarbon groups substitued by an alkoxy, aliphatic ester, halogen or hydroxy group, but excluding compounds in which said replacement of hydrogen atoms in the compound is effected onyl by substituents selected from aliphatic hydrocarbon groups, halogen groups and aliphatic hydrocarbon groups substituted by a halogen group, or a salt thereof contain- ng a physiolgically acceptable ion or ions, are of value in the :reatment of patients having a toxic concentration of a metal, particularly iron, in the body whilst the iron complexes of such compounds are of value in the treatment of iron deficiency anaemia.
