The text in this online chapter will be supplemented by video material and also sections of texts from books in the Royal Society of Chemistry e Book collection which support this topic area.Here, the solubility of the drug can be an issue, along with competitive complexation with proteins in the bloodstream.In some examples this complexation might be desirable to aid distribution of the drug to where it is required, in others it can be detrimental.Table 9.1 lists the recommended daily intakes for some of the essential metals, together with some of the effects of deficiencies in these metals (reproduced from Table 1.1).Table 9.1 UK Food Standards Agency reference nutrient intake (RNI) for adults (and the US Department of Agriculture dietary reference intakes (DRI)) and the effect of deficiency for selected essential metals.
