All of these are great. The last one is lacking but the most simple of the bunch.

If your program doesn't require a pharm textbook, you could buy your own. It'll definitely help you learn mechanism of actions across drug classes and is good for other tidbits of info. I used this book in one of my grad school pharm classes: http://www.amazon.com/Basic-Clinical-Pharmacology-13-E/dp/0071825053/ref=sr_1_1?ie=UTF8&qid=1464611598&sr=8-1&keywords=basic+and+clinical+pharmacology


I had the 11th edition but I just referenced it and it had a whole table listing the suggested anti inflammatory doses for NSAIDs and actually said 600mg QID for ibuprofen, so either that doc was making stuff up, or was basing his info off of some newer journal articles.
Either way, a textbook is a good place to start
