Term: drug design https://doi.org/10.1351/goldbook.DT06960 Definition: drug design includes not only ligand design, but also pharmacokinetic and toxicity, which are mostly beyond the possibilities of structure- and/or computer-aided design. Nevertheless, appropriate chemometric tools, including experimental design and multivariate statistics, can be of value in the planning and evaluation of pharmacokinetic and toxicological experiments and results. drug design is most often used instead of the correct term 'Ligand Design'. Related Terms: 1) drug (http://doi.org/10.1351/goldbook.D01863). 2) pharmacokinetic (http://doi.org/10.1351/goldbook.PT06835). 3) toxicity (http://doi.org/10.1351/goldbook.T06414). 4) multivariate statistics (http://doi.org/10.1351/goldbook.MT06974).
