Safety of Shujinjianyao pill in clinical real world

Abstract

Background:Low back pain is a common health problem worldwide, which also is a leading cause of long-term disability and has an important effect on the global economy and society. Usually, conservative therapies are used to treat low back pain. As a kind of Chinese patent medicine, Shujinjianyao pill (SJJYP) has a great curative effect on low back pain. However, its safety has not been studied yet. Therefore, we carried out this clinical trial to observe the safety of SJJYP in the real world.Methods:First, participants need to meet the medication standards according to inclusion and exclusion criteria. Then, participants are conducted safety examination before taking SJJYP. After qualified screening, participants can be enrolled into the group. Second, all enrolled participants will receive SJJJYP for a period of 4 weeks. During the observation period, participants need to return to the hospital for a subsequent visit after 2 weeks of medication, and come to the hospital for safety check after 4 weeks of medication. Third, telephone follow-up is used to investigate any participants’ physical discomfort after 6 to 8 weeks (2–4 weeks after medication withdrawal). After all these steps are completed, clinical observation is finished. If any adverse events occur during this process, we will record them in time. When serious adverse events occur, we will use nested case–control study to explore the causes and mechanisms.Discussion:This study will obtain the safety results of SJJYP in clinical real world, which will offer a scientific basis for clinicians in the treatment of low back pain, and also provide a methodological basis for the safety study of other medicines.Trial registration:ClinicalTrial.gov registration number is NCT03598153. This study was approved by the ethics committee of Wangjing hospital, China Academy of Chinese Medical Sciences (WJEC-KT-2018-012-P002).
