The unequivocal and precise identification of the drug product is the basis for compliance. Compliance is one of the critical factors with regard to drug safety and efficacy in any therapeutic area. Since elderly people have frequently to take more than one drug during a day, many differentiation options are necessary to achieve an unequivocal identification of the different drug products. Differentiationcan either be achieved by color, by form or by imprint. Taken the very small size of drug products into consideration, neither the filigree imprint nor the variations in form are sufficient for the differentiation purposes.
