This is an excellent reference book for anyone studying medicine or on a medication course,as i was. It is informative and easy to use, with a comprehensive list of medicines and even conditions at the back. Looking up medicines is a cinch, and it gives you all the known names for each one. It is easy to read and easy to understand, even for someone without much medical knowledge and remains current for quite some time, although a new edition is brought out twice a year. I have tried many other reference materials during the course of my work, but i can honestly say that this is the only one that is any good. Plus, it is commonly used by doctors, nurses, etc so you have the same information they do. The only let down is the buy-it-new price, around £26, but you can buy it used for less than a tenner on amazon, so not a problem!
