Pharmacology

You are correct in that you mostly learn the drugs by class, but you also need to know what drugs belong to that class obviously. When I took Pharm I would study all of the indications, side effects, contraindications, patient education, etc that pertained to that class as a whole and then I would focus on the specific medications in that class that stood out for one reason or another such as this is the only med in this class you can give to kids or only this med has this specific serious adverse effect. I recommend making your own study guides for the tests and breaking down and arranging the vast amounts of material to suit your study habits and strengths, and dont get overwhelmed with trying to study each individual drug.
