Reddit mentions of Basic and Clinical Pharmacology, 11th Edition (LANGE Basic Science)

I liked "Basic and Clinical Pharmacology" by Bertram Katzung. I know that Rang Dale & Ritter is often on reading lists, but I didn't like it at the time I was in the market for a textbook.

A more "friendly" text is "A Primer Of Drug Action" by Robert Julien. It's a great book -- something that you can read all the way through almost in a recreational way (pun not intended; however it does have very good sections on the "recreational" drugs). Not sure how to get across what I mean... it's a "good read" rather than a textbook that one uses primarily for reference. I'd say that it's perfect for someone who wants a good introduction with a moderate amount of technical information.

Just noticed that SodiumKPump has already recommended Robert Julien's book.
