Objective: There is a huge amount of new information about drugs in the scientific world every day that cannot be tracked in time and the practitioner cannot be remembered. There is a large flow of patient data, in the clinical practice, where medical information systems are used, which, unfortunately, is not fully processed in real time. The objective of the present study was to decide about the problem by using ECF. Methods: As the semantic core in the ECF was used by the UMKB, which accumulates knowledge from all areas of practical medicine and basic science, starting with the clinical experience of doctors and ending with general pharmacology. Within the framework of UMKB, a separate area is developed, where knowledge in the field of pharmacology is presented in the form of a semantic network. Results: The patient was successfully treated with the support of the ECF system. Pain syndrome in the patient was stopped almost immediately after 2 days, sleep was restored, and the patient stopped waking up in the middle of the night due to pain. Conclusion: Based on the results of the tests the ECF system was introduced into practice in several Russian clinics.
