Reddit reviews Rang & Dale's Pharmacology Flash Cards

I highly recommend the Rang & Dale Flashcards, they're extensive and very clear. The whole set consists of about 300 cards, split into around 40 sections (each based on a specific class of drug/body system/specific disease). On the front of the card is a diagram representing an overview of the system with the name of a drug at the top. On the reverse side is all the relevant info regarding the drug (actions, MOA, parmacokinetics, use and adverse effects). As you move on to the next card the drug is added to the fist overview diagram at its point of action, so that when you get to the final drug of the section you have a full representation of the physiology and how each drug effects it.

It may be worth mentioning that they are written by British professors, and I don't know if the US pharmacology curriculum differs from the British (assuming you're studying in the states).
