Elder patients with complex diseases need to take a large number of medicines. Therefore, the unitdose heat-sealing film for tablets and capsules is used to help people take medicines in Japan. However, there are still some problems with unit-dose packaging, such as low adherence, difficulty opening and the issue of the large amount of waste involved. In this study, we evaluated the conventional unit-dose packaging and developed it which suit for Japanese patients and medical service. We made a prototype of the new unitdose packaging and evaluated usability of this one in medication through comparison with conventional unitdose heat-sealing film. This was a prospective, controlled 2 week trial conducted in 20 elder patients. According to the questionnaire, Almost patients satisfied with the new packaging due to ease of choosing right unit which should take. Furthermore, the number of remained medicine in the study group is less than the control group. The control group generated larger amount of trash than the study group. The new unit-dose packaging reduced omission of a medication and amount of trash. Moreover, the questionnaire represents that the new packaging is easier to use than existing one.
