Scientific Achievements

Dr. Paul Janssen was one of the most productive pharmaceutical researchers of the 20th century. During his career Dr. Paul and his team were responsible for the discovery of over 80 drugs, including 25 antipsychotic medicines. He and his team made discoveries in many areas, including anesthesia and pain management, psychiatry, mycology and gastroenterology. Among the discoveries to which he contributed are:

  • Discovery of HALDOL® (haloperidol), the first effective antipsychotic medicine.
  • Discovery of FENTANYL® and other anesthetics.
  • Discovery of RISPERDAL® (risperidone), the most widely prescribed atypical antipsychotic in the world.
  • Development of Tibo anti-HIV compounds.
  • Development of IMODIUM® (loperamide HCL), a widely used anti-diarrheal that can be lifesaving in the event of acute diarrhea
  • Development of VERMOX® (mebendazole), a vital drug for use in parasitic worm infections.
  • Development of a wide range of anti-fungal medications, including DAKTARIN® (miconazole nitrate), NIZORAL® (ketoconazole) and SPORANOX® (itraconazole).
  • Development of a wide range of medicines for research including anti-fungals, anti-psychotics, anti-histaminics, anti-neuroleptics.

Dr. Paul was the author of 468 scientific papers indexed in the Science Citation Index (SCI). He also authored many conference proceedings, book chapters, and papers in publications not indexed by the SCI.

As of January 2006, his 468 indexed papers have received 21,716 citations and continue to be cited heavily. In addition, Dr. Paul has co-authored papers with more than 850 different scientists.

Here is a list of Dr. Paul's 10 most highly cited papers, all of which have been cited over 300 times. Only about 0.15 percent of research papers published, reach this level of citation. To have published 10 papers in this group is remarkable. Two of them have been featured as Citation Classics in Current Contents, with commentary on the background to the paper from Dr. Paul.
