I bought this pocket-sized book while doing my senior medschool rotations, but of course it is designed for physicians in primary care or internal medicine residents, as a quick lookup of relevant drug informaton and treatment options.
The different topics start with a description of the disease, followed by the treatment plan, and then describes the medictations using lots of reference to tables. Precautions and important concepts are written in bold.
I would especially recommend it for residents as a fast review before starting a rotation.
