Objective To explore the current research status, research hotspots and future research directions of off-label use of Chinese patent medicine.
Methods Related literature reports on off-label drug use of Chinese patent medicine published before July 2025 were retrieved from CNKI, WanFang, VIP database, and PubMed, then CiteSpace 6.4.R1 was used to make a visual analysis of the issue time, author, institution, keywords, literature type and other aspects.
Results A total of 58 relevant articles were ultimately included, the earliest of which was published in 2006; 182 scholars and 84 institutions contributed to research in this field, with the articles primarily published in 37 journals. The literature on off-label use of Chinese patent medicine involved 78 keywords, with "rational drug use" being the most frequently occurring and clustering keyword. The literature was divided into six main types: hospital medication data analysis, literature data analysis of off-label use, expert consensus on off-label use, clinical research on off-label use, literature review on off-label use, and other types.
Conclusion The current research in the field of off-label use of Chinese patent medicines remains weak, characterized by a minimal number of publications, highly con-centrated geographical distribution, and predominantly single-center retro-spective prescription analyses, lacking high-quality clinical efficacy and safety evidence. Systematic research framework and management standards have yet to be established in this field, urgently requiring a shift from "phenomenon description" to "evidence construction". Multicenter collaborative research and the development of a characteristic evidence-based evaluation system of traditional Chinese medicine should be encouraged to promote rational clinical medication.
