I focus my review on two portions of the book's sub-title. 1)Non-technical and 2) Revised and Updated.
Robert Julien writes as he speaks. He demystifies the vast information in this field and clarifies it. However, for the reader who wants in-depth information about the topics, there are treasures to be found. Your "aha !" and "ohhhh" buttons will be pushed constantly.
I appreciate the conscientious way Dr. Julien and his publisher have kept the book "revised and updated." There are so many research findings being reported all the time. New medications come on line. This makes many excellent (and expensive) books obsolete within a couple of years. "A Primer of Drug Action" remains current and useful.
But seriously, they sometimes are slow in being returned. I buy them two at a time.
This is a real medical-grade book that gives a very complete and easy-to-understand introduction to the drugs used to treat psychiatric disorders.
Don't waste time with popular books that either claim psychoactive drugs will solve all our problems, or alternately, that they are useless brain-damaging poisons.
*A Primer...* is the most honest, readable introduction to the psychotherapeutics I know of. It is essential reading for the informed patient or caregiver.
