Medicinal nitrous oxide is commonly used for anesthesia and pain relief. In order to manage the distribution of medicinal nitrous oxide and prevent it from being used for recreational purposes, the medicinal nitrous oxide has been included in the trace and track system of medicinal products according to Pharmaceutical Affairs Act since October 1^st, 2020. The medicinal product license holders and wholesalers are required to submit the tracking and tracing information electronically before 10th of every month.

There are diverse ways for the pharmaceutical company to declare the trace and track data, such as data import, automatic upload, or online data entry etc., and the operating interface of the declaration system was improved to simplify the declaration process for pharmaceutical company. In addition, the system has established the cross-reference and statistical analysis function, which is able to provide statistics, inquiries, and output of reports.
