Survey on prescriptions of similar-looking formulations to patients requiring ophthalmological operations

抄録

The present study aimed to determine the frequency of drug use with devices, such as inhalers and self-injectors, and use of two or more topical agents with similar formulations in patients who required ophthalmological operations. We retrospectively surveyed the medical charts of 1,244 patients admitted at Showa University Hospital East Branch between January 2018 and May 2019. Of these patients, 40.2％ （n＝500） received medications through devices and two or more topical agents with similar formulations. In general, the patients who underwent ophthalmological operations had poor vision or loss of vision. To avoid misuse or underuse of devices and topical agents, pharmaceutical companies need to consider universal designs for patients with poor vision or loss of vision.
