Metronidazole Research: Historical Developments and Future Directions

Metronidazole is widely used around the world to treat anaerobic, parasitic, and bacterial infections. Yet, despite its significance, a comprehensive review that weaves together its historical Breakthroughs and charts a course for future research is still missing. To assess the published literature on Metronidazole research indexed in the Scopus database using bibliometric analysis tools. A bibliometric analysis was conducted on metronidazole research in the Scopus database for the period 1960–2024. Data were analyzed using R software, VOS viewer, and Cite Space to explore qualitative and quantitative trends. Results: The first article published in 1960, the number of scientific publications has increased, especially after 1985. 6,172 publications were identified with 160,000 citations, showing a steady annual growth rate of 6.26%, reflecting a vibrant and steadily growing field. Notably, publication rates soared after 2024. WANG was the most prolific author, while China and the United States led in productivity, with 13% international collaboration. The Journal of Antimicrobial Chemotherapy is the leading journal in terms of publication venue. Network analysis spotlighted Metronidazole, tetracycline, and vancomycin as central antibiotics. Highly cited studies focused on Clostridium difficile infection, Helicobacter pylori eradication, and bacterial vaginosis. Over time, research themes have shifted from traditional pharmacology and microbiology to innovative areas such as nanotechnology, biosensing, computational modeling, and green chemistry. The research on Metronidazole shifting into four promising directions for future exploration: harnessing artificial intelligence to predict resistance, leveraging computational tools to uncover new applications, embracing green chemistry to minimize environmental impact, and advancing precision medicine through genetic biomarkers.
