Jon Njardarson at the University of Arizona is well known for his group’s Top200 Drugs Posters. They chronicle the structure of the top 200 pharmaceutical drugs by both US retail sales and US prescriptions.
Now, his group has changed focus slightly. The group takes a disease category, like the nervous system, and lists all small-molecule drugs that have been approved for this category. They are listed in chronological order. This is a really neat twist to a nice series of posters out of the Njardarson group. There are about a dozen or so of these posters, and they are made freely available on the group’s website.
