The product isn't really detailed about the medication. It doesn't give mechanism of action of the different medications. It just gives the classification. However, it is good just to freshen up your memory and gives you an idea on the different medications which you are not familiar with. It gives the most important side effects of the medications and nursing considerations for it. It is good in a way that it is made simple. It's less confusing that way and important details can be retained by our memory.
