I'm on a systems-based curriculum, and have been following along with first aid, Goljan path, and Lange Pharm flash cards. From my incomplete experience, all the drugs I've seen in first aid can be found in Lange cards (the 2nd edition). Since the second edition of Lange (as well as the new Brenner set) just came out last summer, I'm not sure anyone can tell you which of these new sets match closely with first aid.
