Abstract
BACKGROUND
Governmental regulations of drug registration and licensing are not always followed by healthcare providers.
OBJECTIVE
To explore the global research growth and patterns on systemic use of off-label and unlicensed drugs to gain knowledge about the magnitude of the problem and the main research themes encountered in this field.
METHODS
SciVerse Scopus was searched for papers on off-label and unlicensed drug use from 1990 until December 31, 2020, without any language limitations. A bibliometric methodology was adopted to present the following indicators: top-cited documents, the most productive countries, top active journals, international research collaboration, the most frequent author keywords, and research themes.
RESULTS
The search query returned 1320 papers with an h-index of 66, published in 721 different journals. The Hospital Pharmacy journal ranked first (n = 43, 3.3%). In total, 5777 authors (median = 3) from 85 different countries contributed to the retrieved papers. The USA (n = 381, 28.9%) ranked first, followed distantly by Germany and Italy. The percentage of documents with international authors for active countries was from 8.8% for China to 42.3% for the Netherlands. The most frequent author keyword next to off-label was children/pediatrics. The keyword unlicensed was less frequently encountered than that for off-label. Major research themes in the retrieved papers focused on off-label drug use in hospitalized children/pediatrics, biological drugs such as rituximab and rFVIIa, psychiatric disorders, regulations, and questionnaire-based knowledge/attitude studies among community pharmacists and physicians.
CONCLUSIONS
Research activity on off-label drug use has witnessed a general increase in the past two decades. The major research theme was off-label drug use in hospitalized children/pediatrics/neonates. The USA and certain European countries made a major contribution to this field.
