re: my comment about "the only three drugs that are..."
I certainly don't mean to equate the three, or more specifically, not trying to equate Lithium with the other two.
The main point is that most drugs have Nitrogen in them; and usually as a part of the active site! Lithium, as an element, is really in a class by itself; and of course it doesn't have Nitrogen "in" it. It probably would be more accurately described not as a drug, but as a trace nutrient (that some people need more than others: -genetics, etc.).
Speaking of pharmaceuticals, is anyone familiar with some of the genomic related work where they're creating thousands of different conformations of a 4 to 8 atom molecule against the neat little gene chips/gene well things? They're looking for some reaction of course, that can then be turned into something therapeutic. It's kinda like learning by studying the effects of knockout genes.
