Pharmacogenetics / Pharmacogenomics

Here's an interesting observation I made while preparing for a presentation. This is a plot of the yearly publications where you can find the term "Pharmacogenetics" or "Pharmacogenomics". This is obtained by just searching via SCOPUS using those keywords.

"Pharmacogenetics" had a steady hit rate of about 50-60 before 1995, and publications took off after that on a steady incline. The word "Pharmacogenomics" was first used in 1997, and then really kicked in after 1999. But what really surprised me was that, unlike "Pharmacogenetics", the hit rate has since plateaued off after 4-5 years.

I am not too sure what the reason is, but I suspect there may be a bit of "Pharmacogenomics" fatigue, and the genomics people moving into broader areas of "Genomics", have stopped using the term "Pharmacogenomics". The "Pharmacogenomics" people by contrast, have tended to remain faithful to their cause and the science continues to expand.
