BRS pharmacology by Sandra L Kim and Todd Swanson
IMHO: The number two pharm resource behind the Pharmcards. Simple single fact cards that focus only on core features of the drugs. Easier material then will be found on many questions on the actual exam.
How to use it: You should know all of these cards by the end of your studies. Run through them with your organ systems as a quick refresher and again later on to make sure you did not miss any key facts.
