In view of the fact that there are numerous reports on medical errors in recent years, this study probes the issue on how to reduce the possibility of recognition errors from medical staffs through the shapes of pharmaceutical packaging containers. The research design and steps are divided into four stages: (1) discuss the relevant literature and the current status of pharmaceutical packaging shapes; (2) summarize the interviews of the professional pharmacists; (3) provide the improved design of drug packaging shapes; (4) obtains the study results through the experimental design, so we can propose the strategy and the design criterion for easy visual recognition of pharmaceutical packaging. The study results are: (1) the shape of current pharmaceutical packaging is mostly bottle container. There are 81 bottle containers and 38 plastic containers among our samplings. ”Drugs acting on the nervous system”, ”Gastrointestinal drugs”, ”Antimicrobial drugs” and ”Ophthalmic preparations” are highly used in bottle containers. ”Metabolic & Nutrient agents” is mainly used in plastic containers. Bottle type containers are primarily with a wide-mouth opening, mostly in round shape. Plastic type containers are in round shapes with a wide-mouth opening. (2) The packages of the container are usually a plain solid color without any variations or design for visual recognition. In our study, we think the ”high homogeneity” of the pharmaceutical packaging shapes is the main key that leads to ”recognition errors”. In terms of the special design of ”container lines” can achieve the role of drug classification segments to increase the tactile awareness which will reduce the possibility of recognition errors and negligence. (3) According to the professional pharmacy staff interviews, the results show that the ”shape factor” is in the first order of a visual recognition process. Therefore, the shape designs of pharmaceutical packaging containers are particularly important, especially under conditions of viewers in the distance. The variations of shape can easily set off the emotional changes and subjective image link. (4) The design trend of pharmaceutical packaging is focusing on the variations in the top neck of the bottle container. The design of the container shape should master the features of the ”pharmacological effect” and help viewers to promote the linkage between the images and drug functions.
