As a bonus, any drugs that mentioned their IRL counterpart in their description now describe their predecessor as ancient, and the new ones as modern. The biggest difference here is just the Antihistamine which was given a full new name. They're similar enough that they'll be recognized (most of them) but different enough for us to call our own and not care what the real medicines are/do since these are our sci-fantasy versions just inspired by them.
